Abstract: A field experiment was conducted during kharif season, 2017 at the Crop Research Farm, Department of Agronomy, SHIATS, Allahabad (U.P.) to concluded the response of different zinc levels and frequency of boron levels on yield and benefit cost ratio and protein content in kharif Greengram (Vigna radiata L.) in Randomized Block Design with twelve treatments replicated thrice. Among the different zinc levels and frequency of boron levels under in treatment T12 i.e.,20 & 35 DAS (0.2% foliar spray) of boron +5.0kg ha-1 of zinc recorded maximum grain yield (2.18t ha-1), stover yield (2.96t ha-1), harvest index (45.14%), protein content (24.56%) whereas the lowest values were recorded in Grain yield(1.46t ha-1), stover yield (1.83t ha-1), Harvest index (40.19%), Protein content (20.26%) in treatment T1Control + 0kg ha-1. The highest gross return (₹ 1156 30 ha-1), net return (₹ 73933.66 ha-1) and b:c ratio (1:2.69) were recorded in T12 i.e.,20&35DAS(0.2% foliar spray) of boron+5.0kg ha-1 of zinc whereas the lowest values were recorded in Gross return (₹ 60230 ha-1), Net Return (₹ 20543.4 ha-1) and B:C ratio (1:1.51) in treatment T1 Control + 0kg ha-1.
