The present investigation was conducted at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (Maharashtra) during Kharif season of 2019. The result of present investigation indicated that, The nitrogen, phosphorus and potassium content, uptake in the grain, straw and availability were significantly higher under the treatment of in situ green manuring with dhaincha followed by green leaf manuring with glyricidia, in situ green manuring with fodder cowpea and control in the descending order of significance. While The nitrogen, phosphorus and potassium content and uptake in the grain and straw were higher under the treatment of spraying of humic acid @ 0.5% (at 30, 45 and 60 DAT) which was followed by spraying of jeevamrut @ 5%, vermiwash @ 5% and control in that descending order of significance. Significantly higher grain, straw yield and total biomass (q ha^-1) was found in treatment in situ green manuring with dhaincha and spraying of humic acid @ 0.5% (at 30, 45 and 60 DAT)
