Rain water use efficiency (RWUE) is the assessment of a rainfed cropping system’s capacity to convert water into plant biomass or grain. Comparison of RWUE of various crops grown under traditional tribal farming system and its performance in drought year will give an insight for prioritization of crops grown in rainfed tribal areas. A study was undertaken in a tribal watershed of Koraput district to prioritize the commonly grown crops based on RWUE and their comparative performance during water stress condition.
