A field experiment was conducted at Birsa Agricultural University, Ranchi, Jharkhand during the kharif seasons of 2016 and 2017 with the main objective to study the effect of foliar application of combinations of different compounds on growth, yield and economics of green gram under rainfed condition. It comprised of ten treatments viz., water spray(control), Urea @ 2% spray, TNAU Pulse Wonder @ 1% spray, Salicylic acid @ 75ppm spray (two times), 19:19:19 (N:P:K) @ 2% spray, Urea @ 2% + Salicylic acid @ 75ppm spray, Boron @ 250ppm spray, Nitrobenzene @ 500ppm spray, DAP @ 2% spray (two times) and KCl 2% spray. Two years data revealed that application of Urea @ 2% + Salicylic acid @ 75ppm through foliar spray at flower initiation stage of green gram along with recommended dose of fertilizer(20:40:20:20 kg N:P2O5:K2O :S/ha) improved green gram grain yield, yield attributing characters, viz. number of pods/plant, number of seeds/pod, number of branches/plant, 100 seed weight and growth parameters, viz. plant height , dry matter accumulation and leaf area index(LAI). Highest plant height (70.27 cm), number of nodules per plant(34.11), LAI (4.5), DMA (313.47 g/m2) , number of branches/plant(8.04), LAI (4.5), number of pods/plant (16.0), seeds/pod (14.4) , 100 seed weight (3.47g), grain yield (1099 kg/ha) , net return (₹35,407.00 /ha) and B: C ratio (1.88) of green gram was recorded with application of Urea @ 2% + Salicylic acid @ 75ppm which enhanced grain yield upto 34% being at par with foliar application of 2% (N:P:K::19:19:19) or 2% Urea along with recommended dose of fertilizer(20:40:20:20 kg N:P2O5:K2O:S/ha).
