Abstract: The agronomic investigation entitled, “Performance of summer green gram (Vigna radiata L.) to fertilizer levels”was undertaken at Post Graduate Research Farm, Agronomy Division of Rajarshee Chhatrapati Shahu Maharaj College of Agriculture, Kolhapur (M.S.), India during summer, 2019. The experiment was laid out in a factorial randomized block design were replicated thrice with twelve treatment combinations comprises three NP fertilizer levels NP1-75% of RDF (15, 30 kg ha-1 N and P2O5), NP2-100% of RDF (20, 40 kg ha-1 N and P2O5), and NP3-125% of RDF (25, 50 kg ha-1 N and P2O5), and four potassium levels as a K0 (00 K2O Kg ha-1), K1 (15 K2O Kg ha-1), K2 (20 K2O Kg ha-1) and K3 (25 K2O Kg ha-1). Yield and economics of summer green were influenced significantly by different NP fertilizer levels. The grain yield (15.14 q ha-1) and stover yield (34.17 q ha-1) of green gram were recorded significantly highest with treatment NP3 (125% of RDF) which was followed by NP2 (100% of RDF) (14.21 q ha-1 grain and 31.55 q ha-1 stover yield respectively). Harvest index (%) of green gram was found non-significant, whereas the highest harvest index 30.69% was found with treatment NP3 (125% of RDF). Economics of summer green production viz., gross and net monetary returns as well as benefit cost ratio were found significantly beneficial with the treatment NP3 (125% of RDF) and which wasfound at par with treatment NP2 (100% of RDF). Among the potassium levels application of K3- 25 K2O Kg ha-1 was recorded significantly maximum grain yield (15.19 q ha-1) and stover yield (33.32 q ha-1) however, it was found at par with K2- 25 K2O Kg ha-1 (14.67 q ha-1 grain and 32.25q ha-1 stover yield respectively). Harvest index remain unaffected due to different potassium levels. Economics of summer green production viz., gross and net monetary returns as well as benefit cost ratio were found significantly beneficial with the treatment application of K3- 25 K2O Kg ha-1 which was found at par K2- 20 K2O Kg ha-1.
