Abstract: A field experiment was carried out in the Farm of BCKV, West Bengal (22095’N, 88050’E) during the summer season of 2010 and 2011 on sandy-loam alluvial soil (Inceptisol), neutral in soil reaction (pH 7.2) having 0.65% organic carbon, 0.08% total N, 27.54 kg ha-1 available P O and 135.15 kg ha-1 available K O, to find out the effect of foliar application of nutrients and Brassinolide on yield of green gram crop. The crop was fertilized with a common dose of N-P O -K O at 20-40-40 kg ha-1 and grown with only one pre-sowing irrigation. The variety Bireshwar was used for this experiment, carried out in RBD with 8 treatments and 3 replications. From the results it was found that foliar application of nutrients (urea and DAP) and Brassinolide had a significant influence on growth and yield of the crop. The growth in terms of plant height, LAI and dry matter accumulation per unit area were significantly higher in the treatments where the plants got nutrients and Brassinolide. Foliar fertilization had significant effect on the main yield component, i.e., number of pods per plant; though, other yield components were statistically at par. The highest seed yield was obtained in the treatment where the crop was sprayed with Brassinolide, 0.25 ppm at 25 DAS and 45 DAS followed by the treatments where the crop was sprayed with DAP (2% solution) at 25 and 45 DAS and Urea (2% solution) at 25 and 45 DAS.Thus, it may be concluded that foliar application of nutrients and Brassinolide had a distinct effect to increase the yield of green gram crop.
