 2001: Implementation  2004: A national agricultural program  Around 90% of farmers’ participatory. 3 but rice crop yield not increase Using quantity of chemical fertilizers further than paddy needs  rely on chemical fertilizers and plant protection chemicals  The increase of input costs, but rice crop yield not increase 3R 3G Statement problems Seed ratesfertilizer amount frequency of pesticide sprayed (while maintaining crop yield) “Three Reductions” (3R): Seed rates, fertilizer amount, and frequency of pesticide sprayed (while maintaining crop yield) et- farm profitfarmers’ health soil quality “Three Gains” (3R): Net- farm profit, farmers’ health and soil quality

Objectives of the study: Analysis of the performance of the 3R3G program 4 #1 find out changes #1 To find out changes in the use of seed, fertilizer, and pesticide after farmers’ participation in the “3R3G” Program #2 analyze factors influencing #2 To analyze factors influencing the use of seed, fertilizer, and pesticide #3 find out the effects of the “3R3G” program #3 To find out the effects of the “3R3G” program on net farm-income, farmers’ health and soil quality

Type of Research: To compare Evaluation type: To compare The changes (before and after), The difference (recommended and actual) To find out Explanatory type: To find out factors influencing Data Analysis 5 T-test: testing the different changes before and after The multiple regression analysis Converted into dummy variables. (r > 0.70) Multi-collinearity of independent variables found (with high collinearity (r > 0.70) excluded) Independent variables with low degree of correlation each other were included in model

Recommendations  Encourage all of farmers using certified seeds, and using Line Seedling Drum for sowing seeds in practice the 3R3G farm Line Seedling Drum  Providing with sufficient certified seed amount directly at farmers’ area  Training farmers on seed treatment or encourage farmers to use treated seeds.  Mobilizing and inviting groups of agricultural hired labors, small farmers and female farmers attending the 3R3G training courses 23
