SRI Drought Study Report
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, number of filled grains, number of chaffy grains, grain yield, and straw yield were compared. The study found that SRI outperformed CMP for most metrics across all states, including higher yields, even during periods of drought. SRI was able to mitigate some impacts of drought and produced better results than CMP in challenging growing conditions with less water.
