The effect of five nutrient management practices on the yield and yield attributes, nutrient uptake and rain water use efficiency in four greengram varieties (Dhauli, Pusa-9531, OBGG-52 and Nayagarh Local) in rainfed upland inceptisol with sandy-loam soil was studied in factorial RBD with three replications during Kharif 2009 to 2012. Significant variety × nutrient interaction was observed withrespect to seed yield, nodulation and otheryieldattributing characters. Based on the mean data over four years (2009–2012), highest seed yield of 5.84 q ha⁻¹ was observed in Pusa 9531 with lime+50% organic+ 50% inorganic treatment followed by Dhauli (5.53 q ha⁻¹) with the same nutrient treatment. Highest RWUE was found in Lime + 50% organic + 50% inorganic treatment in all the varieties followed by 100% organic treatment in Dhauli, Pusa-9531 and OBGG-52 but in 50% organic + 50% inorganic treatment in case of Nayagarh Local. The uptake of N, P and K was also observed to be the highest in Lime + 50% organic + 50% inorganic treatment in all the varieties.
