Variety × Nutrient management interaction in greengram for important yield attributes under rainfed red lateritic inceptisol

2018

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.
