The document summarizes the findings of a drought study comparing the System of Rice Intensification (SRI) method to conventional method (CMP) of rice cultivation across several states in India. Key metrics such as plant height, number of tillers, productive tillers, panicle length, grain yield, and straw yield were compared. The study found that SRI outperformed CMP for most metrics across all states, including higher grain and straw yields, even during drought conditions with lower than normal rainfall. SRI plants were taller and had more tillers and productive tillers than CMP plants. SRI also resulted in longer panicles with more filled grains and fewer chaffy grains compared to CMP.
