July-September 2007, Vol. 2, No. 3
International Rice Research Institute
Food and water are
two of the most
important necessities
for survival, but, with an
increasing demand for food
and a looming water crisis,
a shortage of both may
be on the horizon unless
innovative technologies are
developed. Water, especially,
is fast becoming a precious
commodity, as more and more
people continue using water
for the household, industry,
and agriculture. Scientists arenow taking on the challenging
task of developing rice
production systems that can
cope with water scarcity.
We begin this special
water-saving issue of RIPPLE
with an introduction to a tech-
nology that enables rice to
be grown in dry land without
flooding, and help farmers
cope with water scarcity:
the aerobic rice system.
Less is moreAerobic rice is a new
way of growing rice that
needs less water than low-
land rice. It is grown like an
upland crop such as wheat,
in soil that is not puddled,
flooded, or saturated. The
soil is therefore aerobic or
with oxygen throughout the
growing season, as compared
to traditional flooded fields,
which are anaerobic.
The difference, however,
between aerobic rice andupland rice is that aerobic rice
produces higher yields, 46
tons per hectare and perhaps
beyond. This is possible
because the crop is grown
in aerobic soil but cared for
with external inputs such as
supplementary irr igation (if
rainfall is insufficient) and
fertilizers. This new way
of growing rice started as
early as the mid-1980s in
China. To differentiate it from
traditional upland rice, the
International Rice Research
Institute (IRRI) coined
the term aerobic rice.
Aerobic rice can be con-
sidered a mature technology
in temperate countries such
as northern China and Brazil,
where aerobic rice area is es-
timated at 80,000 and 250,000
hectares, respect ively. In both
countries, breeding programs
since the 1980s have resulted
in the release of several high-yielding aerobic rice variet-
ies by crossing high-yielding
lowland rice varieties with
traditional upland types. In
northern China, new high-
yielding aerobic varieties such
as Han Dao 277, Han Dao
297, and Han Dao 502 were
released in the late 1990s
with yield potential of up to

6.5 tons per hectare. After a
20-year breeding program in
Brazil, aerobic rice var iet-ies have yielded 57 tons
per hectare under sprinkler
irrigation in farmers fields.
In the tropics, aerobic
rice systems are still very
much in the research and
development phase. IRRI
started to develop variet-
ies for the Asian tropics in
2001. The first generation of
tropical aerobic rice variet-
ies consists of IR55423-01
(Apo) and UPLRI-5 from the
Philippines, B6144-MR-6-0-0
from Indonesia, and CT6510-
24-1-2 from Colombia. These
varieties were mostly derived
from crosses between indica
and tropical japonica parents.
Current research fo-
cuses on the development
of improved management
systems and on breeding
further improved varieties.
Managing aerobic riceThe usual way of planting
aerobic rice is the same as
how you would plant wheat or
maizeby dry direct seeding.
And, like these cereal crops,
aerobic rice can be rainfed,
supplementary irrigated, or
fully irrigated.
However, compared with
flooded rice, weeds pose a
bigger threat in aerobic soils.
To control
weeds, the
use of pre- or
post-emer-
gence her-
bicides is
recommendedwhen weed
pressure is
high, plus
additional
manual or
mechani-
cal weeding
in the early
phases of
crop growth.
Yield decline has also
been experienced after
growing aerobic rice con-tinuously each year on the
same piece of land. Possible
reasons for declining yields
or even failures to grow crops
for the first time in an area
could be soil-borne pests
and diseases such as fungi,
nematodes, and root aphids,
particularly in the tropics.
Current research focuses
on determining the causes of
yield decline under continu-
ous cropping, and on develop-
ing resistant varieties, suitable
management options such as
crop rotation, and integrated
weed management practices.
Latest researchIn the Philippines, par-
ticipatory testing of aerobic

rice by farmers is being done
in the provinces of Tarlac,
Nueva Ecija, Bulacan, and
Bohol. The 2003-05 experi-
ments produced yields of up
to 6.4 tons per hectare. Farm-
ers in India are also tryingout aerobic rice in their fields,
and they have identified well-
performing varieties. Water
savings were also achieved at
3040% for production levels
of 4 tons per hectare. (Learn
more about Indias progress
inRIPPLEVol. 2, No. 2.)
Varieties are being tested
in Lao PDR, while activi-
ties in northeast Thailand
are set to evaluate geno-
types and start on-farm teststo overcome problems of
labor shortage and weeds.
Experiments are actively
ongoing in China, and the
Chinese experience of
developing aerobic rice will
be highlighted at theInterna-
tional Workshop on Aerobic
Rice set for 22-25 October
(see page 7 for details).
Airing out aerobic riceVarious activities are
being done to extend aerobic
rice to farmers. Demon-
strations are being held for
farmers, researchers, and
other stakeholders at most
experimental sites in China,
the Philippines, India, and
Thailand. In the Philippines,
the technology is included in
a number of training pack-
ages on water-saving tech-
nologies in rice production.
Training courses for farm-
ers and irrigation engineers
have been organized at thePhilippine Rice Research
Institute and in several
provinces in the Philippines.
In China, aerobic rice
concepts are circulated
through two national exten-
sion networks. Seminars have
been organized at all sites for
the targeted farming com-
munities. The China Central
Television network, a major
TV network in the country, is
coordinating with the ChinaAgricultural University to
produce a video on aerobic
rice to be shown nationwide.
Internationally, informa-
tion on aerobic rice is shared
through the IRRC and the
CGIAR-Challenge Program
on Water and Food (through
the STAR project). Lectures
have been given in the
Philippines and in Vietnam.
Posters and oral presentations
were given at conventions and
at various Chinese national
conferences and workshops.
With predictions sug-
gesting that many Asian
countries will have severe
water problems by 2025,
aerobic rice gives hope to
farmers who do not have ac-
cess to enough water to grow
flooded lowland rice. The
Water-Saving Work Group
of the IRRC is committed tofur ther developing this new
technology and making it
available to farmers in Asia.

AWD technologygains momentumin Bangladesh
Bangladeshi farmers harvest boro rice under AWD conditions. Thepotential of AWD to reduce water input and its effect on yieldand water productivity depend on soil type, groundwater table depth,and climate.
After years of field tests,
the alternate wetting and
drying (AWD) technology is
now officially promoted by
the Bangladeshi government
and is being adopted by its
farmers.
In December 2005, Dr.
T.P. Tuong, head of the Crop
and Environmental Sciences
Division of the International
Rice Research Institute
(IRRI), made a presentationon water-saving technologies
at the Bangladesh Rice
Research Institutes (BRRI)
Department of Water Man-
agement. Dr. M.A. Sattar,
department head, used some
of the concepts, submitted a
proposal to the government,
and received funds to test
AWD in fields.
Fast forward to February
2007, when Dr. Tuong
conducted a seminar with
nongovernment organizations
(NGOs) to discuss the
implementation of AWD in
farmers fields. These initia-
tives led to the testing of
AWD by the Asian Develop-
ment Bank-funded project
Development and Dissemi-
nation of Water-Saving Rice
Technologies in South Asia,
and the Bangladesh Agricul-
tural Development Corpora-
tion (BADC).
On 14 May, a group of
high-level professionals,
policymakers, and farmersattended a crop-cutting
ceremony at BADCs Madhu-
pur Farm, where AWD is
being tested during the
current boro (winter) season.
The Irrigated Rice Research
Consortium supported the
attendance of Dr. Tuong.
Mr. Md. Abdul Aziz,
secretary of the Ministry of
Agriculture, inaugurated the
harvesting. He asked the
countrys Agriculture Infor-
mation Service to be more
active in promoting the
technology, and st ressed the

need to work with NGOs and
other countries. Since AWD
can possibly aggravate weedproblems, he discouraged the
use of herbicides. He empha-
sized that Bangladesh should
save labor by using the
drum seeder for direct
seeding, save urea by using
the leaf color chart, and save
water by adopting AWD to
make rice cultivation more
profitable.
The crop was transplant-
ed on 8 February and grown
under AWD technology. It
needed only 5 irrigations,
while conventional practice
needed 9 irrigations. Under
AWD, paddy yield was 8.4
tons per hectare, while
the conventional practice
produced 8.1 tons per hectare.
After learning about the
yield and water savings, Mr.
Aziz directed the BADC to
validate this method on 1% of
land on its 23 farms all overthe country. He also asked
research and development
organizations of the country
to prepare an action plan
to validate AWD on a wider
scale for the boro season next
year.
The Barendra Multipur-
pose Development Authority
(BMDA), a government
organization, was asked to
adopt AWD more intensively,
because their clients are
farmers who have to pay for
water. Therefore, the BMDAis the perfect body to test the
benefit of the technology. The
Department of Agriculture
Extension (DAE) was asked
to be the lead agency in
different parts of the country
to expose farmers to the
technology, while BRRI was
directed to monitor the
profitability for farmers and
their level of acceptance.
During the conference,
Dr. M. Zainul Abedin, IRRI
representative for Bangladesh
highlighted the background
and need for water-saving
technologies in the country.
Keynote speaker Dr.
Tuong described the details of
water-saving technology
through AWD, and presented
impressive statistics that
highlighted the advantages of
saving water and the associ-
ated irrigation costs. Thetechnique was quite new for
many of the 90 participants
from BADC, DAE, BMDA,
and the other NGOs present.
After Dr. Tuongs presenta-
tion, a discussion was
facilitated by BADC Chair-
man Mr. Abdur Razzaque.

The truth about alternate wetting and drying
In alternate wetting
and drying (AWD),
the field is allowed to
dry for a certain number
of days before applying
irrigation water. The number
of days that the soil is left
dry can vary from 1 day
to more than 10 days.
A practical way to im-
plement AWD is to monitor
the depth of the water table
in the field using a perforated
or punctured water tube.
After an irrigation applica-
tion, the field water depth
will gradually decrease in
time. When the water level(as measured in the tube)
is 15 centimeters below the
surface of the soil, it is time
to irrigate and flood the soil
with a depth of around 5
centimeters. Around flower-
ing, from 1 week before to 1
week after the peak of flow-
ering, ponded water should
be kept at a 5-centimeter
depth to avoid any water
stress that would result in
potentially severe yield loss.
The threshold of 15
centimeters is called safe
AWD, because this will not
cause yield decline since the
roots of the rice plants will
take up water from the
saturated soil and the perched
water in the roots. The field
water tube helps farmers see
this hidden source of water.
In safe AWD, water savings
may be relatively small,
around 15%, but yield will not
be smaller. After creating
confidence that safe AWD
does not reduce yield, farmersmay experiment by lowering
the threshold level for
irrigation to 20, 25, or 30
centimeters, or even deeper.
A decrease in yield may be
acceptable when the price of
water is high or when water is
very scarce.
In safe AWD, the follow-
ing rules should be observed.
AWD irrigation can be used
from a few days after trans-
planting (or a 10-centimeter-tall crop after direct seeding)
until first heading. In the
period of first heading to 1
week after flowering, keep the
field flooded at a 5-centimeter
depth. After that, during grain
filling and ripening, apply
AWD again. When many
weeds are present in the early
stages of crop growth, the
implementation of AWD can

mism about the technology.
Special guests included Dr.
Nur-E-Elahi, BRRI director
general, Dr. Rahim Uddin
Ahmed, DAE directorgeneral, and Mr. Abdul
Mannan, BMDA executive
director.
Dr. M.A. Hamid Miah,
IRRI liaison scientist for
Bangladesh, synthesized the
points of discussion:
a) AWD has reduced the
frequency of irrigation
without affecting yield, and
yield was even a little higher
in AWD-treated fields. Water
saved through this techniquecan help increase the irriga-
tion command area, or the
area served by a specific tube
well, by at least 10%.
b) The cost of irrigation
decreased, reducing farmers
production cost. This haspositive effects for shortages
in diesel fuel and groundwa-
ter depletion.
c) AWD is an easy
technology for farmers to use.
Farmers buying water by
volume are likely to be fast
adopters of this technology.
d) The extra cost of
weeding is compensated for
by saving on fuel cost and
extra yield. Thus, farmers
may not receive cash benefitsimmediately, but large-scale
adoption has a positive
environmental impact
nationally.
Dr. Hamid Miah sug-
gested that partnership be
developed with BADC, BRRI,BMDA, DAE, IRRI, the
Bangladesh Water Develop-
ment Board, Rural Develop-
ment Academy, Local
Government and Engineering
Department (LGED), elec-
tronic media, and NGOs.
In another event, Dr.
Tuong presented an invited
seminar for the scientific
community on technologies
for efficient use of water in
rice production at the Bangla-desh Agriculture Research
Council on 15 May. It drew
around 60 scientists and
managers in the water and
agricultural sectors, and was
well covered by the media.
The seminar promoted furtherawareness on water manage-
ment issues and presented the
Water-Saving Work Groups
efforts to help solve them.
A training course on
AWD is being planned for
August this year at BRRI, to
be facilitated by Dr. Ruben
Lampayan (IRRC Water Sav-
ing WG leader) and scientists
of BRRIs Department of
Water Management.

ment routine is needed and
local recommendations for
flooded rice can be used.

on the dry soil just before
irrigation is applied.

The pursuit of water-savingcontinues in Vietnam
S
ince 2005, the Water-
Saving Work Group
of the Irrigated RiceResearch Consortium (IRRC)
has established activities on
water management and water-
saving in rice in the Mekong
Delta in collaboration with
Vietnams Plant Protection
Department (PPD).
After an initial field
visit of staff from the Interna-
tional Rice Research Institute
(IRRI) to the Central Delta
region and a 1-day work-
shop at Long Xuyen in AnGiang Province in January
2005, the PPD and An Giang
Department of Agriculture
organized a series of train-
ing activities for farmers and
established demonstration
fields on alternate wetting
and drying (AWD) technol-
ogy. Subsequent outreach
activities resulted in 161
farmers testing AWD on 168
hectares in 11 districts of An
Giang in the winter 2005/
spring 2006 seasons, followed
by around 1,500 farmers on
1,700 hectares in the sum-
mer of 2006. In Tien Giang,
31 farmers tried out AWD in
the summer, while 51 tested
it in the autumn of 2006. In
central Vietnam, PPD also
tested AWD in Quang Nam,
Thanh Hoa, and Nghe An.
In outreach activities,
AWD technology wasintegrated in the successful
Three Reductions, Three
Gains program, which
proved to be a good example
of the integrated crop man-
agement approach. By asking
farmers to record all opera-
tions, inputs, and outputs
obtained during the cropping
season, this gave them an idea
of the yield obtained and
yield-contributing factors,
and if there were any savings
in water and irrigation (pump-
ing) costs.
An initial analysis of
data from around 900 farmer
respondents in the summer
of 2006 in An Giang con-
firmed that AWD reduced
water use and pumping costs.
AWD farmers had, on aver-
age, two pumping operations
(to irrigate their fields) less
than the regular practice of
continuous flooding, savingaround 200,000 Vietnamese
Dong (US$13) per hectare.
Yields were significantly
higher with AWD (5.63 tons
per hectare) than with the
regular practice (5.36 tons per
hectare), although in absolute
terms, the differences were
quite small. An important
factor contributing to higher
yields under AWD manage-
ment seemed to be a decrease
in lodging (rice plants falling
over), which is often as-
sociated with wet seeding,
commonly practiced in the
Mekong Delta. With AWD,
lodging was on average 10%,
whereas, with standard prac-
tice, it was on average 19%.
In late 2006, an extensive
baseline survey was done in
the Mekong Delta area where
farmers are adopting AWD,
to determine their attitudes
toward and practices forwater management. With the
initial promising results of
AWD in the Mekong Delta,
plans were developed to
take water-saving technolo-
gies to other parts of Viet-
nam where water is scarcer
than in the Mekong Delta.
On 6 March, Dr. T.P.
Tuong, head of the Crop and
Environmental Sciences
Division of IRRI, gave a
presentation on Water-saving
irrigation: from research to
technology dissemination,focusing on AWD, at the Soil
and Fertilizer Research
Institute (SFRI). The seminar
was organized by the Vietnam
Academy of Agricultural
Sciences (VAAS) and was
attended by some 30 leaders
and scientists from VAAS,
SFRI, PPD, the Directorate of
Science and Technology of
MARD, Food Crops Research
Institute (FCRI), the Depart-
ment of Agriculture, Depart-ment of Agricultural Exten-
sion, and Hanoi Agricultural
University.
On 3 May, Dr. Bas Bou-
man (IRRI), Dang Thanh
Phong (provincial PPD),
and Le Quoc Cuong (PPD)
organized a 1-day training
course and workshop on water
management and water-sav-
ing technologies hosted by
the Northern Regional Plant
Protection Center in Hung
Yen Province. Some 40
participants from provincial
PPDs in the Red River Delta
attended the training, as well
as representatives from FCRI,
SFRI, and World Vision.
The training included
lectures on AWD and on
sound water management
practices such as land level-
ing, bund maintenance, and
construction of field channels.After the lectures, a forum
was organized, followed by a
short brainstorming with the
participants on the usefulness
and potential dissemination
of the presented technologies
in their own regions in the
Red River Delta. At the end
of the day, posters and fold-
ers in Vietnamese and tubes

to monitor field water depth
to assist in the implementa-
tion of AWD were distr ib-
uted to all the participants.
Three VAAS institutes
have expressed great inter-est in contributing to further
research, scientific develop-
ment, and dissemination of
water-saving technologies in
Vietnam (especially AWD):
FCRI, SFRI, and the North-
ern Mountainous Agriculture
and Forestry Institute (NO-
MAFSI). During a meeting at
FCRI on 2 May, Dr. Bouman
met with VAAS President
Dr. Nguyen Van Bo, FCRI
Director Dr. Nguyen VanTuat, SFRI Director Dr. Bui
Huy Hien, and several staff
members to discuss further
collaboration on water man-
agement. The first research
already began at SFRI in
2005 with field experiments
that looked at the integrated
effects of AWD and improved
nutrient management on rice
production at three loca-
tions in Vietnam. This was
an activity with the IRRC
Productivity and Sustain-
ability Work Group. In May
2007, plans were made to star tfield experiments on AWD
under different water table
depths at the research station
of FCRI at Gialoc, Haiduong.
Exciting opportunities
were identified to link the
IRRC Water-Saving Work
Group with another consor-
tium hosted by IRRIthe
Consortium for Unfavor-
able Rice Environments
(CURE)through collabora-
tion with VAAS-NOMAFSIin the mountainous regions
of northern Vietnam. One of
the projects under the um-
brella of CURE is par t of the

use of scarce water resources.
During a project field trip to
Yen Bai Province on 4-7 May,
technologies developed by the
Work Group, such as AWDand aerobic rice, were identi-
fied as very promising options
for farmers growing lowland
rice in inland valleys or on
terraces on sloping hillsides.
Plans were drafted for the es-
tablishment of demonstration
fields of AWD and partici-
patory variety selection for
aerobic rice for the spring rice
crop in 2007 and 2008. Also,
further experimentation on
AWD and/or aerobic rice can
be pursued at the research sta-
tion of NOMAFSI at Phu ThoAs follow-up to these
developments on water-saving
technologies at the VAAS in-
stitutes, a training course and
planning workshop are set for
September or October 2007.

Integrated weed management in Nepal
As part of the
continuing effort of
the Irrigated Rice
Research Consortiums
(IRRC) program to build
capacity, it stretches itshelping hand to Nepal, where
the rice-wheat cropping
system is common.
Weeds are among the
major constraints in the rice-
wheat system. To address
this problem, 15 of Nepals
researchers and technical
officers were equipped with
knowledge and understand-
ing about weeds and their
ecology and control.
The training on integrat-ed weed management was
conducted on 25-27 April. It
was spearheaded by Dr. Jagat
Ranjit of Nepals National
Agricultural Research
Council in collaboration with
David Johnson and Joel
Janiya of the IRRC Labor
Productivity Work Group, andthe International Fund for
Agricultural Development.
Topics covered in the
training were introduction to
weed management, weed
identification and classifica-
tion, weed population dynam-
ics and survival, crop-weed
interaction, tillage-weed
interaction, weed control
methods, and herbicide
application.
The team of trainersincluded Dr. Dharma Raj
Dangol, who delivered a
lecture on weed identification
and herbarium preparation;
Dr. Madhav Joshi, who gave a
talk on tillage-weed interac-
tion; and Dr. Ranjit, who gave
a lecture on the positive valueof weeds, weeds associated
with different crops, and
herbicide use in Nepal. Dr.

country. Community action
and the use of the community
trap barrier system are
the key management
strategies implemented in
Vietnam and Indonesia by
the project Sustainable
implementation of ecological
rodent management. This
is funded by the Australian
Centre for International
Agricultural Research.The projects objectives
are related to the goals of the
Irrigated Rice Research
Consortium, particularly in
disseminating mature lowland
rice technologies. IRRC
Coordinator Dr. Grant
Singleton, a rodent expert, is
the project leader at the
International Rice Research
Institute.
Now in its second year,
the project held a review and
planning workshop for
Vietnam in Ha Nam Provinceon 19-20 April to discuss the
lessons learned from activi-
ties in 2006what needs to
be improved, what went well,
and what to do for 2007 and
beyond. A few days before the
meeting, a training event on
the biology of rats and
ecologically based rodent
management (EBRM) was
conducted by Dr. Peter Brown
of the Australian Common-
wealth Scientific and Re-
search Organisation (CSIRO),
together with Dr. NguyenTuan of the Plant Protection
Institute (PPI). The partici-
pants were staff of provincial
plant protection departments
(PPD) and plant protection
stations of the district sites,
and village extension officers.
Dr. Peter Roebeling
of CSIRO (project coor-
dinator) and Mr. Huan
of PPD South organized
the workshop, assisted by
Mr. Tran Thanh Tung.
Dr. Roebeling gave an
overview of the workshops
objectives. Results of the
projects first year of imple-
mentation were presented
by Ms. Nga of Ha Nam and
Mr. Lam of An Giang. Dr.
Florencia Palis presented
initial results of the survey
on knowledge, attitudes, and
practices in Ha Nam and An
Giang. Interestingly, farm-
ers identified television and
video as preferred pathways
for receiving information on
new technologies. Develop-
ing a video will help exten-sion staff promote EBRM
among farmers in Vietnam.
Scaling-up of project
activities to the government
and nongovernment orga-
nizations, and institutions
in other districts, is the top
priority for this year, with
scaling-out to farmers set
for the following year.

Fun-filled farmers field day and forum
One bright, summer
day in San Jacinto,
Pangasinan Province,Philippines, farmers
and scientists gathered
enthusiastically for a farmers
field day and forum on rice-
growing technologies. About
148 farmers, local government
staff, extension specialists,
and municipal agriculturists
from five towns came on 9
March, along with 9 guests
from the Irrigated Rice
Research Consortium (IRRC),
Philippine Rice Research
Institute (PhilRice), and the
Department of Agriculture
(DA). The event was made
possible through partnership
among the local government
unit of Barangay Lobong, San
Jacinto; PhilRice; and the
International Rice Research
Institute through the IRRC.
Participants first vis-
ited the rice field of farmer
Francisco Aquino, a farmer-partner who began using site-
specific nutrient management
(SSNM) in November 2006.
After a ceremonial harvest-
ing of his crops, a lively
forum between farmers and
experts began. The experts on
the panel were Engr. Aurora
Corales and Mr. Rolando San
Gabriel of PhilRice, munici-
pal agriculture officer Floren-
tino Batin, DA regional field
unit representative Wilfredo
Pallaya, and Mr. Joel Janiya,
Dr. Ruben Lampayan, and Dr.Grant Singleton of the IRRC.
Questions varied from
fighting leaf blight disease
(the yellowing and wilting of
leaves and seedlings) to the
inevitable global warming
concern. Regarding the attack
of tungro, a viral disease
caused by green and zig-
zag leafhoppers, Mr. Janiya
advised farmers to practice
synchronous planting, which
means planting areas within
2 weeks of each other. Dr.
Lampayan, on the question
of how much fertilizer is
needed and when to apply
it, advocated use of the leaf
color chart and SSNM as a
guide to help farmers make
fertilizer recommendations
for their own fields. When
asked how to manage their rat
problems, Dr. Singleton said
that the trap barrier system
is only one tool that is idealfor severe infestations, and
he encouraged the whole
community to participate.
He emphasized further that
farmers should first learn the
rats breeding system and its
relationship with its environ-
ment, to know when and how
to manage its population.
Engr. Corales urged
farmers to shop for ideas
on technologies during
events such as this, and to
cooperate and help each
other. When you do things
together, hand in hand, no
one will stumble, she said.
(Get to know more about
technology promotion expertAurora Corales on page 13.)
As the forum came to a
close near noon, it was clear
that, based on the turnout of
participants and the spirited
discussion among them, the
farmers in Pangasinan were
receptive and eager for
effective rice-growing
technologies and venues such
as this to learn them from.

Hermetic storage: a hot topicin Indonesia
D
ecision-makers
and researchers
from nationaland provincial research
institutions from West
Java, South Sumatra,
North Sumatra, and
South Sulawesi,
extension workers
from West Java,
and distributors of
hermetic storage systems
from the Philippines and
Indonesia gathered on 24
March at ICFORD, Bogor,
to discuss issues andstrategies to disseminate
hermetic storage systems
to farmers in Indonesia.
Five years of research
at the International Rice
Research Institute (IRRI) and
three years in Indonesia have
shown that hermetic or air-
tight storage can help double
the life of rice seeds, main-
tain good milling quality,
and protect grains from pests
such as insects and rodents,
without using pesticides. In
a hermetic storage system
such as the IRRI Super Bag,
the atmosphere inside the
storage container is modified
through biological activities
in the grain and respiration
of insects, resulting in a
drop in oxygen and increase
in carbon dioxide levels. In
this modified atmosphere,
insects cannot survive.The meeting was con-
ducted as part of the Irrigated
Rice Research Consortium
(IRRC) activities in Indone-
sia. It was organized by the
IRRI Indonesia office and
hosted by the Indonesian Cen-
ter for Food Crop Research
and Development (ICFORD).
During the meeting, research-
ers from the Indonesian Cen-
ter for Postharvest Research
and Development (ICAPRD),
the Indonesian Center for
Rice Research (ICRR), and
the provincial technology
assessment centers (BPTPs)
in Medan, Makassar, and
Palembang gave updates on
research findings in Indone-
sia. IRRI provided a summary
of findings in other countries.
Representatives from Grain-
pro Inc., the international sup-
plier of commercial hermetic
storage systems and the IRRI
Super Bag, and from the
Agribusiness Club Jakarta,
distributor of the locally made
hermetic bagKantong Semar,introduced their products.
Participants agreed
that hermetic storage is a
practical technology that
can improve storage of rice
seeds, paddy, and other
crops. Several private seed
companies in Indonesia
have already started buying
hermetic storage systems,
but the anticipated adop-
tion of farmers still requires
public-sector involvement in
the promotion and dissemi-
nation of the technology.In the afternoon ses-
sion, the 40 participants
identified additional adap-
tive research needs and
discussed issues related
to national dissemination
to farming communities.
As an immediate follow-
up, a research team was
formed to collect region-
specific data on potential
target groups and their
existing storage practices.Standardization of testing
methods and hermetic storage
systems was another impor-
tant issue to be addressed.
Providing training to
farmer intermediaries and
farmers is critical for a
successful introduction of
the technology. This can becomplemented with informa-
tion dissemination through
the Indonesian Rice Knowl-
edge Bank. For national
dissemination, the hermetic
storage systems can be intro-
duced through the Indonesian
Prima Tani Program, which
focuses on accelerating the
transfer of research results
to Indonesian farmers.

The pocket-sized guide
introduces the concept of
yield gaps and the underly-
ing constraints. The func-
tions of each nutrient are
explained in detail, with a
description of the deficiency
symptoms and recommended
strategies for improved
nutrient management. The47-page color annex provides
a pictorial guide to the
identification of nutrient
deficiencies in rice.
This 2nd edition is
about to be translated into
several languages, includ-
ing Bangla, Chinese, Hindi,
Indonesian, and Vietnamese.
To make this guide as
widely accessible as possi-
ble, the publishers decided not
only to sell the guide through
their Web sites and book-stores, but also to make the
guide available in electronic

Rice science and farmers
Waves of action
When, in 1961, the
International Rice
Research Institute
rose from Higamot Hill,
which was once a rustic area
planted to coconuts, citrus,
bananas, and pineapples,
a well-known Filipino
educator who was visiting
the place said: SomehowI find it difficult to see the
connection between this
20th-century Institute and
the man who plants r ice.
Five years after that remark,
IRRI turned over to the
Philippine government 50
tons of IR8 seeds. In addition,
IRRI distributed 5 tons in
two-kilogram packages to
the first 2,359 farmers to
request such seed in person
at the Institute. The press
popularized these seeds as
miracle rice. It was said that
within exactly a year of the
release of IR8 seeds, adequate
seed supplies were available
to meet local demand. This
was also the start of a new
era, dubbed as the Green
Revolution, in the deliberate
and intensified connection
between rice science and
the rice farmer. These seedsand their many successors,
which are the products of
rice science, have reached
farmers even in remote areas.
Some insightful les-
sons, experiences, observa-
tions, and research findings
from relevant R&D activi-
ties are cited here to illus-
trate what the new thinking
contributes to the knowl-
edge-intensive character
of emerging rice cultural
management practices.
Integrated pestmanagement (IPM)
The concept of IPM is
intellectually seductive. It is
not a package of technology
for pest control. It involves
new ways of thinking, seeing,and doing things not only on
the part of farmers but of ex-
tension workers, researchers,
policymakers, and the pesti-
cide industry. IRRIs perspec-
tive on IPM includes the basic
premise that no single pest
control method can be suc-
cessful over a long period of
time. IPM combines resistant
cultivars, agronomic practices
known to reduce losses due
to pests, and conservation
practices that preserve and
increase natural enemies.
Integrated nutrientmanagement (INM)
The simple rule, Feed
the rice plant as needed is a
very appropriate description
of INM. It applies to nutri-
ents, water, and pesticides,and implies timing, amounts,
and what inputs to feed. This
is quite a contrast to the blan-
ket prescriptions for fertilizer
applications of yesteryear.
The current concept is site-
specific nutrient management
(SSNM), which is an infor-
mation- and technology-based
agricultural management sys-
tem to identify, analyze, and
manage site soil, spatial, and
temporal variability within
fields for optimum profitabil-
ity, sustainability, and protec-
tion of the environment.
In this approach, farm-
ers knowledge and experi-
ence become vital for the
efficient management of
nutrients in these environ-
ments. It is a knowledge-intensive process for both
scientists and farmers.
The leaf color chart
and the minus-one element
technique are examples of
simple tools that deliver
simple messages to farmers
to assist them in making deci-
sions about when, how much,
and what nutr ients to apply.
Controlled irrigationand water-saving
Rice is a thirsty crop
and the production of 1
kilogram of rice requires
an average of 3,000 liters of
water. Increasing scarcity of
water has brought water-sav-
ing technology in the form
of controlled irrigation to a
test for farmers adaptation
and adoption using a farmer
participatory approach. Con-
trolled irrigation, also knownas alternate wetting and
drying, entails an irrigation
schedule in which, contrary
to the normal practice of con-
tinuous flooding, water is ap-
plied to the field a number of
days after the disappearance
of ponded water. Just like pes-
ticides and fertilizers, water
must now be used judiciously,
Gone are the heydays of scientists old blanket prescriptions on pest
control and fertilizer application. A paradigm shift from prescriptions to
decisions has occurred, and this is proven by new concepts and technologies
that are often shared with farmers using the participatory approach. In this
chapter of her book Rice in Our Life, Philippine national scientist and
outstanding rural sociologist Dr. Gelia Castillo talks about rice sciencetechnologies and products, including some of the IRRC technologies.

but the use of irrigation water
is much more difficult to
control because it is a com-
mon property resource that is
often collectively managed.
After a 3-year implemen-
tation of controlled irrigation
in a study in Tarlac, Philip-pines, farmers found no yield
difference between their
practice and that of controlled
irrigation using less water.
Water savings were about
2030% compared with their
traditional practice. Con-
trolled irrigation saved time,
labor, and expenses because
farmers did not spend as
much time in irrigation.
Seeing is believing is notenough
Based on what we have
learned from IPM, INM, and
collective action experiences,
seeing is believing will no
longer suffice. Some, if not
most, of what is involved
in integrated crop manage-
ment, in growing a healthy
crop with minimal health and
environmental costs, is not
going to be directly visible
to the naked eye and will not
always be immediately expe-
rienced. Seeing and thinking
not only in the abstract but
also in the future must be
learned. The pedagogy of this
learning process, particularly
the social learning part, has
scarcely begun to unravel.
We know, however, that
we need to make significant
additions to the old adage To
see is to believe such asTo do is to believe;
to use is to believe;
to know is to believe;
to understand is to
believe; but
to adapt is to succeed for
adaptation localizes the
application of ecological
principles and the practice of
technology.

A quest to increase Indonesiasnational rice supply
An estimated 1015%
of the rice produced
by Indonesian
farmers does not reach the
market because postharvest
losses are high. These losses
consist of shattered grains
during harvesting and
transport, grains eaten by
animals and spilled in sun-
drying, and losses in rice
mills due to poor equipment,
poor maintenance, and low-
quality raw material (paddy).
In addition, the remaining
rice that reaches the market
is often of poor quality with
low head rice, many broken
grains, wrong moisture
content, and discolored grains
from delays in postharvest
operations and improper
drying. The poor quality
grain is often downgradedto Grade 3, which sells
at highly discounted
prices, typically around
20% less than Grade 1.
Improved postharvest
management and technologies
can therefore help increase
the milled rice available in
the country and can signifi-
cantly lead to better qual-
ity and healthier rice.
The Postproduction Work
Group of the Irrigated Rice
Research Consortium cur-
rently contributes to reducing
postharvest losses in Indone-
sia by piloting hermetically
sealed storage systems in
collaboration with the As-
sessment Institute of Agri-
cultural Technology (BPTP)
in North Sumatra, South
Sumatra, West Java, and
South Sulawesi. These storage
systems include the Super
Bag orKantong Semarwith
a 50-kilogram capacity for
the village level, and larger
commercial systems with
5200-ton capacity for the
commercial sector. The seeds
kept in hermetic storage forthe next seasons crop keep
their germination rate above
90% even after extended stor-
age, and thus ensure even and
vigorous crop establishment.
This leads to reduced seed
rates and higher yields com-
pared to normal seeds. Paddy
that is kept in hermetic stor-
age before milling typically
results in milled rice having
10% higher whole grain than
paddy from open storage.The Work Group, in col-
laboration with BPTP South
Sumatra and the South Suma-
tra Forest Fire Management
Project, also supports the
introduction and adaptation of
flat-bed dryers for mechanical
drying of paddy. The dryers
can be used by rice millers,
traders, drying service pro-
viders, and farmers groups.
These dryers improve the
quality of paddy compared
to the traditional sun-drying
method, and thus increase the
milling recoveries and head
rice recoveries of rice mills.

A different take onpest management
A2-week training
onEcological
management of
pests (rodents, insects,
and weeds)biological,
economic, and social
dimensions was held at IRRI
on 19-30 March. This was an
innovative and broad-reaching
workshop because integrated
ecological approaches to pest
management rarely include a
combination of rodent, insect,
and weed management, as
well as social and cultural
dimensions of technology
transfer. The aim of the
workshop was to foster the
importance of population
ecology in pest management,
with an emphasis on
farmer participatory
research as a foundation
for technology transfer.
During the course,
participants were able to
acquire knowledge and skills
in using scientific approaches
and computer technologies
to study pest management
at an agroecosystem level.
The course also included an
understanding of the differ-
ent processes and factors that
influenced farmers decision
making in pest manage-
ment, in which participants
developed different ways to
effectively t ransfer knowledge
to target end-users. A field
excursion to interview local
farmers using their newly ac-
quired skills was a highlight
for many of the part icipants.
Fourteen participants
from Belgium, Cambodia,
China, India, Myanmar,
Pakistan, the Philippines,
United Kingdom, and Viet-
nam attended and success-fully completed the course.
There were two PhD students:
Vincent Sluydts working in
Tanzania in eastern Africa
and Alex Stuart working in
Baler, Aurora Province, in the
Philippines. Unfortunately,
two of our colleagues from
Africa had to withdraw a few
days before the course began.
The course was facili-
tated by Dr. Grant Singleton,
who was also the coursecoordinator, and Professor
Charles Krebs (emeritus
professor, University of
British Columbia, Cana-
da). There was an impres-
sive lineup of an enthu-
siastic team of resource
people (from IRRI unless
otherwise indicated):
Dr. Lyn Hinds (CSIRO
Entomology, Australia),
Dr. David Johnson, Dr.
Yolanda Chen, Dr. K.L.
Heong, Professor Zhang
Zhibin (Institute of Zool-
ogy, China), Dr. Bhagirath
Chauhan, Dr. Debbie Temple-
ton, Dr. Noel Magor, Dr. Flor
Palis, Mr. Arnold Manza, Ms.
Jo Catindig, Mr. Joel Janiya,
Ms. Arelene Malabayabas,
and Ms. Trina Mendoza.
Engr. Eugene Castro, Jr.,
completed a monumental task
in facilitating the training
across such a wide range of
disciplines. And, despite the
competing demands on his
time, he did this with tremen-
dous enthusiasm and some-how continued to be smiling
at the end of the two weeks!
The participants found
the training course to be
challenging but in a positive
way. They rated it as a great
success. We are confident
that the participants will
be excellent emissaries for
what we see as an exciting
advance in pest management
over the next decadecom-
munity-based ecological
management. Community in
this context has a deliberate
double meaning; a community
of smallholder families in-
volved in the management of
a community of pest species
(insects, rodents, and weeds).
The main sponsors for
the course were the IrrigatedRice Research Consortium,
the Institute of Zoology of
the Chinese Academy of
Sciences, LEARN IT (Link-
ing Extension and Research
Needs through Informa-
tion Technology), and the
Rice-Wheat Consortium.

Getting her hands dirty
Nueva Ecija
is often
referred to
as the rice bowl
of the Philippines,since it is the largest
province and biggest
rice producer in
the Central Luzon
region. Rightfully so,
Nueva Ecija is home
to the Philippine Rice
Research Institute
(PhilRice), the
countrys lead agency
for the planning,
coordination,
implementation, andmonitoring of all rice research
and development activities.
The famous rice-producing
province is also called
home by one of PhilRices
top technology promotion
experts, Engr. Aurora Corales.
Engr. Corales, or Au,
is a senior science research
specialist at the Technology
Management and Services
Division of PhilRice. She
handles the integrated area-
based technology promo-
tion project, which aims to
make the most of the r ice
and rice-based technolo-
gies developed by PhilRice
through innovative strategies
and partnerships with local
government units, nongovern-
ment organizations, and the
private sector. This project is
being implemented in close
coordination with the branchstations of PhilRice in differ-
ent provinces. The collabora-
tion between PhilRice and the
International Rice Research
Institute on the development
and promotion of improved
technologies on rice produc-
tion falls under this project.
In addition, the technol-
ogy promotion activities
within Central Luzon and
Pangasinan Province are also
under her study leadership.
With all the responsibilities
under her belt, not a week
goes by that Engr. Corales
doesnt head to one of the
branch stations or farmers
fields to monitor the projects.
Out in the field, she
provides technical assis-
tance to partners, conducts
hands-on training on tech-
nologies, and holds consul-
tation meetings to identify
key production constraints.
The PhilRice group is also
responsible for conduct-
ing farmers field days and
information campaigns, such
as the successful Boo Boo
Rat campaign (seeRat patrol
in Nueva Ecija, Philippines
inRIPPLEVol. 1, No. 3).
Her efforts are now pay-
ing off. Year 2006 was a goodone for her, as she received
the 2006 Pagasa Award, a
nationwide competition held
yearly by the governments
civil service commission.
Her division also bagged the
Outstanding Division award
at PhilRices 21st anniversary
celebration, and she, as Out-
standing R&D staff (level 2).
It is difficult doing
technology promotion
because we are dealing with
different personalities, Engr.
Corales says. Some farmers
are more receptive than
others. But it is very fulfillingbecause we see that we are
serving and helping them.
When I go to the fields, they
ask so many questions. This is
probably why I got pulled into
this kind of work.
This agricultural engi-
neer started off as a statisti-
cian in 1982 at the Philip-
pine Cotton Corporation in
Pangasinan, where she met
her husband, Rizal. When I
was studying for my mastersdegree in rural develop-
ment, I didnt realize that I
was already shifting careers.
I was then working with
community organizers in my
office at the Philippine Rural
Reconstruction Movement,
and they were using differ-
ent terms in the local dialect.
It was a shocking experi-
ence for me, she reveals.
Nowadays, Engr. Corales
is most comfortable deal-
ing with farmers, especially
since her father is a farmer
as well. Another hobby that
she finds comfort and peace
from is gardening. My
husband and I enjoy work-ing together in our small
garden, she shares. When I
wake up each morning, I look
at my plants and see if they
have any beautiful flowers.
This mother of three girls
hopes to continue her studies
in community development,
so she can better equip herself
to help farmers. Our farmers
are in a continuous cycle of
debt. The sad thing is most of
the proceeds of sellingpalay(rice grains) will be used to
pay their loans, she says.
Her advice to Filipino
farmers is to cooperate with
one another to help uplift
their sector. Do not rely only
on the government for you to
progress; continue to strive
hard and not give up because
of poverty, she says. Many
technologies have been dis-
covered to help in rice-grow-
ing; let us not waste them.

The doctor is out and about
It was a long journey
indeed for this medical
doctor turned secretary
general of the Myanmar
Rice and Paddy Traders
Association (MRPTA) torealize his true calling. As
diverse as these disciplines
are, one thing remains
constantDr. Myo Aung
Kyaws concern for people,
especially the poor.
He received his medical
degree in 1984 and opened
his own clinic in 1985 in his
hometown in Pathein, Ayeyar-
waddy Division (in Myanmar,
a division refers to a province
or state). Around 250 patientssought his care every day,
30% free of charge (includ-
ing monks and other religious
people, and the poor and old
patients), and his clinic turned
into a small hospital. I was
like a robot and had no time
to rest, no time to spend withmy family, even to take care
of my parents when they be-
came ill, narrates Dr. Kyaw.
That was the time he began
thinking of shifting from pri-
vate practice to government
service, and pursuing his
dream of becoming a surgeon.
So he worked under the
governments Minist ry of
Health from 1990 to 1997,
and, although he planned
to take clinical subjects,
he was assigned to handle
administrative matters such
as promotion and transfer
of employees, budgets, and
training. In 1994, he receivedhis diploma in management
and administ ration at the Yan-
gon Institute of Economics.
While working in the
government, his fathers
health worsened and he had
to take over two rice mills
of medium-scale capac-
ity in Pathein. He opened
a wholesale market cen-
ter in Yangon in 1995.
It was in 1997 when the
former chair of the MRPTAapproached Dr. Kyaw dur-
ing a rice-trading affair and
invited him to become a
member. He accepted, and the
rest, as they say, is history.
Now, Dr. Kyaw is the
secretary general of the orga-
nization, and he finds fulfill-ment in his pursuit to uplift
the livelihood of poor farm-
ers. The MRPTAs mission
is to create a fair and free rice
market trading environment
not only locally but also with
export markets that is in line
with government policy, he
explains. We aim to help rice
producers increase their trad-
ing volume of rice and rice
products, and we take part
in implementing government
economic policy guidelines
by cooperating with govern-
ment agencies and nongov-ernment organizations.
Part of Dr. Kyaws duties
include conducting training
and seminars on postharvest
technologies for farmers and
private entrepreneurs. In early
February, the MRPTA spon-
sored a seminar on rice pro-
duction technology in Nat Ta
Lin, West Bago, with the Thit
Cho Government Seed Farm
of the Myanma Agricultural
Services. In March, Dr. Kyaw
went to Mandalay, the upper
part of Myanmar, to present
a seminar on postharvest and
grain-drying technology. He
also recently gave a lecture on
commercial dryers in May in
Ayeyarwaddy, Bago, Manda-
lay, and Yangon divisions.
Although his tasks are
demanding, they arent as
time-consuming as when he
was still working round theclock as a doctor. He now has
time for his family
and for hobbies such
as gardening, traveling, pho-
tography, reading, and medi-
tating. A cert ified homebody,
Dr. Kyaw recounts a summer
holiday that didnt go quite as
planned. My family plannedto go to the beach for 4 days,
to go swimming and play
football. But, after one night,
we got bored and decided to
go home. We were happier
at home, he recalls fondly.
His plans for MRPTA,
though, are on track and
unswayable. He envisions
more capacity building among
farmers, millers, and trad-
ers by providing them with
training, and developingpostproduction technologies
in grain drying, seed stor-
age, milling, and more. This
dream entails the full sup-
port and cooperation of the
organization members.
Life does begin after
40, Dr. Kyaw says in hind-
sight. Before I turned 40, I
always considered things
from my point of view only,
but that changed. We might
have difficulties and unfore-
seeable things along our path,
but I believe we can overcome
them with compassion,
goodwill, and efforts and
sacrifices.
He may not be practicing
medicine any more, but many
more farmers all over Myan-
mar are benefiting from his
genuine kindness and sincer-
ity to help those in need.
