The document compares paddy production using conventional methods, SRI (System of Rice Intensification), and SRI with the addition of BGA (blue-green algae). SRI with BGA resulted in slightly lower grain production but higher straw and seed weight compared to SRI alone. The use of BGA was more economical than fertilizers and increased biomass, moisture content, and crop sizes in subsequent seasons. Future plans include promoting BGA application in 100 hectares of paddy fields and orienting more farmers on its use.
