Abstract: 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. Results showed that vegetable crops have higher RWUE than cereals and pulses. Among the cereals, maize (RWUE, 7.77 kgha-1mm-1) and finger millet (RWUE, 3.06 kgha-1mm-1) performed better in upland areas, while paddy (RWUE, 7.45 kgha-1mm-1) in low lying jhola land. Among the pulses and oilseeds, black gram and niger have emerged better in drought situation and the increase of RWUE of black gram and niger was 45 and 73%, respectively. The RWUE of cabbage (53.27 kgha-1mm-1) and cauliflower (49.55 kgha-1mm-1) was higher than other vegetables, but, under water stress condition, french bean performed better. In sufficient rain year ginger and turmeric showed higher RWUE (19.79 and 17.81 kgha-1mm-1, respectively) but there performance drastically decreased during drought year. Farmers prefer the combination of lowland paddy at jhola land, finger millet, niger, black gram, cabbage/cauliflower and beans at medium to upland and ginger and turmeric at the beda land (land parallel to jhola land) during sufficient rainfall year. During drought year, lowland paddy at jhola land, finger millet, niger, black gram at upland and beans at beda land can be a better choice. Therefore, the study will be a ready-reckoner to the planners/policy makers to devise effective crop combination for better economic return to the rainfed tribal farmers of Koraput district.
