Farmers Using Improved Nutrient Management Technology and GAPs
This information was collected from the weekly report and village survey conducted by SSMC
field staff. Against the target of 400, a total of 590 farmers (148%) have used improve nutrient
management methodologies in the first year of SSMC.
SSMC First Annual Report | January-December 2017 12
Activities
The SSMC program focused on: (i) evaluating the role of secondary and micronutrients,
including the application of different compound fertilizers, on crop productivity as affected by
soil acidity, and (ii) working through extension workers to promote balanced plant nutrient
management solutions for improving crop productivity, crop profitability, and soil fertility. The
number of activities and the intensity of engagement vary by season. According to the approved
annual work plan,4 the SSMC program required implementation of activities during Year 1, all
attributed to both T. Aman and winter 2017-18 crop seasons, to achieve the two objectives of
SSMC. Table 7 highlights the progress of project technical activities. Of the seven activities, five
activities met or exceeded the target, and the remaining two could not. The reason is mainly
because the project started field activities following the crop calendar during T. Aman, and the
winter crops could not be harvested yet. The winter crops are still in the field, and harvest will be
completed in March 2018. The field day will be conducted at the harvest time, followed by
farmers’ training.

Technology Transfer
Farmer Training
Farmers’ Selection
The farmer training5 programs are
designed to improve farmers’
knowledge on improved nutrient
management with emphasis on
increasing awareness and knowledge
about GAPs, the importance of liming in
acidic soils, and the role of
micronutrients and compound fertilizers.
Training takes place in batches of 30 farmers; each batch consisted of 25 progressive farmers,
including demonstration farmers and five fertilizer retailers. Farmers were trained by Deputy
Directors, UAOs, SAAOs of DAE, and senior staff and field coordinator (FC) of SSMC. A total
of 33 batches of farmer trainings were conducted. The division of training is as follows: five per
crop before planting (5 x 6 crops in Year 1 = 30 trainings) and five at harvest, combined with
field days (5 x 6 crops in Year 2 = 30 trainings). The remaining 60 will be conducted from
mid-Year 2 to mid-Year 3 in the same format.
Training Program
In the second half of 2017, 28 batches of training were conducted with 838 participants (men,
women, and fertilizer retailers). The training was conducted differently in upazilas. Of the 838
trained participants, 700 were progressive farmers, including 28 demonstration farmers, and 110
(13 percent) were women. In addition, 138 agro-input retailers were also present. Modules
followed during training programs included PowerPoint and oral presentations, group
discussions in a participatory approach, and practical demonstrations on identification techniques
of adulterated micronutrient fertilizers. The number of farmers attending the training is provided
5 In Year 1, SSMC planned to conduct 60 farmers’ trainings. Thirty farmers’ trainings will be conducted before
planting for six crops, and the remaining 30 farmers’ trainings will be at harvest time and combined with field days.
In Year 2, 60 farmers’ trainings will be conducted.

Field Demonstrations
The project will support a series of on-
farm demonstrations that display the
highest yielding and/or most cost
conserving practices as compared to
current farmer practices. In particular,
demonstrations will focus on improved
soil management and GAPs.
Technology/methods results demonstration is an important activity of the SSMC program. The
demonstration plots consist of four plots, each measuring 200 square meters. Treatments include:
T1 – farmers’ practice; T2 – recommended fertilizer dose without lime; T3 – recommended
fertilizer dose with lime; and T4 – OCP compound fertilizer + straight fertilizer with lime,
keeping other management practices constant. In Year 1 of SSMC, 50 demonstrations were
established out of the targeted 60, among which 10 were in the 2017 T. Aman season, and 40
(non-rice) were in winter 2017. Appendix 4 provides the details of demonstrations by crop.
Status of Rice Demonstrations
There were 20 rice field demonstrations planned in Year 1. Out of 20, 10 demonstrations were
established in Year 1. Another 10 demonstrations will be established in January 2018 due to the
cold weather. The status of demonstrations is presented in Table 9. Figure 4 shows locations of
10 T. Aman demonstration plots using a global positioning system (GPS) device.

Results of Rice Demonstrations
In T. Aman 2017, SSMC-IFDC
established 10 demonstrations in 10
upazilas in six project districts. In
these demonstrations, the project used
only two modern high-yielding
varieties, BRRIdhan49 and
BRRIdhan51. Due to excessive rain
and devastating flood, almost all the
demonstrations were affected and
incurred serious damage.
The data show that OCP compound fertilizer + straight fertilizer with lime performed better than
all other treatments used in the demonstration plots. Average yield increased 17 percent for OCP
compound fertilizer + straight fertilizer with lime over farmers’ practice and 7 percent over the
recommended dose without lime. Also, the data indicated that balanced fertilization with and
without lime performed better than the farmers’ practice.
Table 10 also shows that within a column, average values followed by the same letters are not
significantly different, but a significant average incremental yield of 785 kg/ha was achieved in
the OCP compound fertilizer plot over farmers’ practice plot. The average numbers of tillers/hill
and panicles/hill have also shown no significant difference between the treatments, but the
average yield difference was more economically profitable for the T. Aman farmers. Appendix 5
provides additional details by upazila. Figure 3 shows the average yield by treatment, and Figure
4 shows locations of 10 T. Aman demonstration plots using a GPS device.

Field Trials
Establishment of Rice and Non-Rice Trial Plots
SSMC/IFDC prepared research protocols on macronutrient and micronutrient omission trials and
the establishment of balanced fertilization trial plots for rice and other non-rice selected crops
(maize, potato, lentil, and wheat). The project consulted with BARI and BRRI scientists and
maintained continuous liaisons with them. Both research institutes provided thoughts and ideas
for better understanding and outcomes. Some modifications on balanced fertilization using
integrated soil fertility management (ISFM)-related trial programs were made based on
suggestions from BARI’s On-Farm Research Division (OFRD) and BRRI’s Soil Science
Division. Different grades of OCP compound fertilizers have been considered during selection of
fertilizer treatments. After a series of discussions and review, trial protocols for all crops have
been finalized and handed over to BRRI as well as to BARI. Final trial protocols were also sent
to OCP Foundation.
On-Farm Trials on Rice Crops
Before establishing the trial plots, the Deputy Director for IFDC-Asia attended a meeting with the
principal scientific officer and head of the Regional Agricultural Research Station (RARS), OFRD
Rangpur of BARI. During the discussion, she emphasized the importance of on-station and on-
farm SSMC non-rice trial activities in different locations. The scientists shared their experiences
and views with her. They were also advised to maintain liaison with the focal point of BARI.
Senior staff of SSMC and other scientists also attended the meeting.
The trial sites are under AEZ-3 (Tista Flood Plain) and AEZ-25 (Level Barind Tract). The selected
varieties were BRRIdhan 49 and BRRIdhan 52. The seedling age varied between 31 and 33 days.
Total treatments were eight with three replications. Total plots were 24. Layout, land leveling,
fertilization, and transplantation were done properly. Table 12 provides the status of on-farm field
trials. Figure 6 shows the location of on-farm field trials on rice.

The field trial site at Kurigram Sadar was inundated by floodwater in August 2017. In the
trial plot at Kurigram Sadar, submergence-tolerant BRRIdhan 52 variety was used, and after
13 days of inundation, floodwater receded from the trial plot. The crop was affected but it
recovered from submergence stress quickly. Necessary gap filling and ail/field bunds
reconstruction work were done properly. Crops in field trial sites at Pirganj of Rangpur were
in the tillering stage and in good condition in August 2017. Treatment effects were
observed in different subplots of two trial sites. BRRI scientists in both the trial sites
placed signboards and plot labels properly.
On-Farm and On-Station Trials on Non-Rice Crops
IFDC signed a grant agreement with
BARI’s OFRD on August 3, 2017, to
collaborate for the activity for sustainable
management of soil to enhance yields
and farmers’ incomes under resilient
production systems, which contributes
to the overall goal of OCP’s Agricultural
Development Project for Bangladesh.
The focal point of BARI informed that,
based on crop suitability, OFRD has selected 11 on-station and on-farm non-rice crop field trial
sites by October 2017. Table 13 provides the on-farm and on-station trials of non-rice crops.
Figure 6 also shows the location of non-rice field trials.

Grain yields of BRRIdhan49 under different fertilizer packages were almost similar.
Comparatively, some higher grains were produced when OCP compound fertilizers were
used with straight fertilizer.
The use of OCP compound fertilizer replaced the use of triple superphosphate (TSP) and
reduced the use of urea by 12 kg/ha, gypsum by 5 kg/ha, and zinc sulfate by 1 kg/ha in T.
Aman season. However, this formulation is not farmer friendly until there is need to apply
straight fertilizer. Potash should be included in compound fertilizer.
Macronutrient and Micronutrient Omission Trial at Kurigram
The trial at the Kurigram site was submerged with floodwater for about two weeks starting
on August 12, 2017.
Rice plants recovered after submergence but after some days, this trial was affected by
bacterial leaf blight disease. Necessary measures were taken, but again at the ripening stage,
grain spot disease was observed.
Grain yields of the recommended dose with and without lime (T1 and T2) are statistically
identical.
OCP compound fertilizer + straight fertilizer (T3) produced 4.26 mt/ha grain, and it was
statistically identical to grain yield of 4.89 mt/ha, which was recorded in the recommended
dose when no lime was added (T1).
Recommended fertilizer dose with liming produced the highest grain yield of 5.18 mt/ha, and
it was significantly higher than the yield of OCP compound fertilizer + straight fertilizer
treatment.
The omission of N (T4) and P (T5) from the recommended fertilizer dose without liming
significantly reduced the grain yield while the omission of K (T6), S (T7) and Zn (T8) had no
significant effects on grain yield.
It is notable that omission of all nutrients except Zn from the recommended dose with lime
significantly reduced the grain yield of BRRI dhan52.
It can be concluded that liming might have some effect on nutrient availability for wetland
rice. However, it will be cleared after a trial in the dry season.
SSMC First Annual Report | January-December 2017 32
OCP Company Gifted Compound Fertilizers
SSMC senior staff of IFDC received the required amount of OCP fertilizers (800 kilograms
or 16 bags) from BADC, Mirpur Seed Multiplication Farm, Dhaka, on July 3, 2017. As per
demand from BRRI and BARI, 175 kg of all the OCP fertilizers were distributed to BRRI
and BARI for use in different rice and non-rice trials. Of the 175 kg, 25 kg were given to the
Focal Point of BRRI. He confirmed receipt of the desired amount of TSP Zn and 12N-45P2O5-
5S-1Zn categories of fertilizers. The remaining 150 kg were given to the Focal Point of BARI.
He confirmed receipt of the desired amount of TSP Zn (50 kg), 12N-45P2O5-5S-1Zn (50 kg),
and 19N-38P2O5-6S-1B (50 kg) categories of fertilizers.
For use in rice and non-rice demonstration plots, 475 kg of OCP fertilizers were sent to the
FC of SSMC at Bogra. An additional 150 kg of fertilizer has been kept at IFDC’s office in
Dhaka. It will be used as per the demand of the DAE field officials and BRRI and BARI
scientists.
The senior staff and FC of SSMC completed re-bagging of different categories of OCP
compound fertilizers by crop at Bogra for 54 demonstration plots to be established in 2017.
These will be gradually distributed among the demonstration farmers through DAE and FC
of SSMC.
The IFDC Deputy Director for Asia attended a meeting with the BADC Chairman at his
office. She discussed the current SSMC activities as well as a future work plan. She extended
her thanks to the Chairman and other officials for their cooperation in providing OCP gifted
compound fertilizer to IFDC. As per requirement of BADC, OCP also provided a boron-
