How does drought-tolerant rice help farmers?
Evidence from randomized control trials in eastern India

By using data from a randomized control trial (RCT) of 1,680 farmers in eastern India, this paper investigates how a drought-tolerant rice variety, called Sahbhagi Dhan, helps farmers. In the RCT, farmers in treatment villages received 5 kg seeds of Sahbhagi Dhan before Kharif, which is the main agricultural season in India, in 2012 or 2013. The paper finds that Sahbhagi Dhan enabled farmers cultivate crops after Kharif partly because of its short duration. The impact was larger when farmers experienced severe drought in Kharif so that farmers can compensate the crop loss in the season. This helps farmers to become less vulnerable against crops chocks. However, the average yield of Sahbhagi Dhan was found lower than that of other rice varieties under both normal and drought conditions. The findings in this paper suggest that Sahbhagi Dhan to be promoted in areas where the potential for double cropping is under-exploited.
