DPRK Agriculture Program:SRI Project in four local farms • Brief history of AFSC agriculture development work in DPRK • New program cycle of agricultural development approach in DPRK • Farm experience with SRI practices and initial reports • Next stage of focus on SRI and some of the issues we are facing
Brief history of AFSC agricultural development work in DPRK • 1990-2000 Humanitarian assistance • 2000-2007 Focus on agricultural development- soil fertility, with winter cover crop and forage • 2007-present Improvement in cultivation methods - rice and corn, tackle shortfalls in production issue and structural challenges Seed breeding and generation advancement - tackle long-term production bottlenecks Soil fertility - address long-term agricultural needs and environment sustainability
The new program cycle of agricultural development approaches in DPRK Three focuses: - Cultivation methods - rice and corn - Seed breeding and generation advancement - Soil fertility
Cultivation methods - rice and corn Based on each farm’s situation, specific location, crop, labor force, natural and economic condition, address immediate needs of increased food production Results: By 2009, 250 hectares of rice paddy in experiments with the new cultivation methods. Average yield increases of 0.5 t to 1 t per hectare
Seed breeding and generation advancement Address one of the fundamental issues of low food production in a poor country which is lack of knowledge and means to have appropriate policy and research opportunities for producing better crop seeds Results: three new rice varieties have been released; positive results from DPRK-based exchange programs with other institutions in Southeast Asia
Soil fertility Address long-term agriculture and environment sustainability issues to find ways to gradually improve soil fertility, with changes in conventional agricultural practice and systematic structure Result: Extremely difficult to find sustainable solutions. Initial findings need more test.
First element: address immediate need for increase food production at farm level Evaluate changes in cultivation methods on the farm for rice cultivation • Farm experience with SRI and initial reports: see pictures below
Reasons and processes for the original introduction of SRI to farms - Ease shortage of labor and resources at planting period, and at the some time, increase crop yield and, if possible, soil fertility. -Establish experimental stages for gradual introduction of new production methods: 1) Seeding 2) Transplanting 3) Water management 4) Other related issues.
In 2009, total experimental area in the four farms was up 250 hectares

Average increase of 0.5 t to 1 t per hectare on 250 hectares of experimental fields
Next stage of focus on SRI and some of the issues that we are facing - Better scientific experimental design for the on-farm trials for finding the best combination of methods in each location -More experiments on different transplanting densities -Look into the possibilities of more efficient water management and ways of weed control -Look into ways to increase the soil biomass -Expand the experiment fields in more farms
