Overview Purpose:

- To compare SRI with conventional and other

methods (i.e. Rice-duck and Rice-fish farming)

- Villagers can choose which method will be suitable

for their actual situation

Project sites: Bac Son, Nam Son and Dich Giao communes, Tan Lac district, Hoa Binh province (1,380hhds)

Timeframe: Summer–Autumn crop 2007

Villagers tried 3 different spacing (22cmx22cm, 20cmx20cm, 18cmx18cm)

Result

Economic aspect Paddies developed well with more tillers

and productive seeds, in comparison to the controlled fields.

The yield of Rice increased by 18% - 55%.

(14/52hhds could get higher yield) Seeds saving

Environment aspect Reduction of insect and disease Water saving

Social impact Reduction of workload of women Enhanced cooperation in the community

Result (continued)

Result (continued)

Villagers could… Understand benefits and difficulties of SRI Find preferable spacing Compare with other methods And choose proper method for each paddy

field with different condition

Bac Son commune

28 hhds applied SRI, but…

- 8 hhds lost their harvest

- 15 hhds could get 150kg/ha yield

- 5 hhds could get 100kg/ha yield

Because big typhoon hit target area in July and

October…… Villagers could get 3t/ha yield in summer-

autumn crop in 2006……

Advantages

Training by experienced experts and farmers

Good facilitation by commune leaders

Close monitoring by JVC and CDC members

Enthusiasm of villagers

Disadvantages/challenges

Storm and heavy rain swept away rice field of some households and/or reduced yields of rice.

Some villagers transplanted late so that the yield of rice decreased.

Some villagers didn’t transplant paddies with proper density and record the process.

Difficulties in water management

- Location of paddy field

- Prevention of mole crickets and rats

Future planning

About 190 hhds will apply SRI in winter-spring crop of 2008

Promotion of ‘farmer to farmer’ Apply SRI to local variety Distribution of technical materials to interested

villagers Strengthen information sharing among

villagers, local governments and other organizations through workshops and newsletters.

Thank your for your attention!
