A field experiment was conducted at Research farm of the Maharishi Markandeshwar (Deemed to be Unviversity), Mullana, Ambala during Summer season of 2023 to determine the “Effect of combined application of nitrogenous fertilizers and organic adjuvants on growth and yield of green gram (Vigna radiata L.)". The experiment was laid out in a Factorial Randomized Block Design (FRBD) with three replications and five treatments (control, 100% RDF (20 Kg N, 40 kg P₂O₅, 20 Kg K₂O and 25 Kg ZnSO₄), 100% RDF + 25% higher Nitrogen, 100% RDF + 25% N through vermicompost, and 100% RDF + 25% N through vermicompost + Rhizobium) applied to two varieties PDM-139 and SML-668. Variety SML-668 accomplished highest number of all parameters like growth parameters, yield attributes and yield. The data was recorded on growth parameters, yield attributes and yield. The results revealed that the highest plant height (cm), number of leaves plant^-1, number of branches plant^-1 and dry weight (g plant^-1) was recorded with the application of 100% RDF + 25% N through vermicompost + Rhizobium and the lowest was recorded in control. Maximum grain yield, stover yield, biological yield and harvest Index was recorded with 100% RDF + 25% N through vermicompost + Rhizobium and minimum was recorded in control. Highest gross return, net return and B:C was recorded in 100% RDF + 25% N through vermicompost + Rhizobium and the lowest was recorded in control.
