The effect of row spacing and foliar application of nutrients on the performance of greengram var. 'K-851'was studied at the Agricultural Experimental Station of Calcutta University, Baruipur, 24-Parganas (South), on Gangetic alluvial soil. The experiment was laid out in a factorial RBD with three different row spacings and four different foliar sprays (750 1/ha), thus giving 12 treatment combinations replicated thrice. The results revealed that row spacing caused remarkable improvement in growth attributes such as plant height, dry matter accumulation, RGR, CGR and NAR at different growth stages which resulted in higher productivity. Maximum CGR, RGR and NAR were observed under 30 cm row spacing closely followed by 25 and 20 cm. Among the foliar treatments, higher CGR and NAR were recorded with spraying of DAP (2%) followed by urea (2%) and KNO, (0.5%). Spraying with DAP (2%) recorded the maximum RGR followed by KNO 3 (0.5%) and urea (2%). The results on yield attributing characters revealed that row spacing and foliar spray had significant effect on the crop productivity in terms of number of pods per plant, number of seeds per pod and 1000-grain weight. Treatment combination of foliar spray of DAP (2%) and 20 cm row spacing revealed 32.67% higher yield over control followed by 25 cm row spacing and foliar spray of KNO 3 (0.5%). The results suggested that for achieving higher productivity in summer greengram, 20 cm row spacing and foliar spray with nutrients like DAP (2%) seemed to be the most effective agronomic practices for greengram cultivation in Gangetic alluvial soil of West Bengal.
