Abstract: A field experiment was conducted during kharif 2018 at Research Farm, Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar to assess the effect of different sources of nutrients on growth, yield, residual nitrogen status and physiology of black gram. The treatment combinations include T1: Control, T2: 100% RDF, T3: 100% N through FYM, T4: 100% N through vermicompost, T5: 50% RDF + 50% N through FYM, T6: 50% RDF + 50% N through vermicompost, T7: 1/3 N through FYM + 1/3 N through vermicompost + 1/3 N through neem cake, T8: 75% RDF + Rhizobium + PSB, T9: 50% RDF + Rhizobium + PSB, T10: 50% FYM + Rhizobium + PSB, T11: Jeevamrit @ 75 l ha-1 + Beejamrit (seed treatment) + Ghanjeevamrit @ 250 kg ha-1. The experiment was laid down in randomized block design with three replications. Results of the study revealed that growth characters, no. of pods plant-1 (32.25), biological yield (3903 kg ha-1), seed yield (1050 kg ha-1) and stover yield (2853 kg ha-1) was obtained significantly highest under 100% RDF which remained at par with 75% RDF + Rhizobium + PSB. Application of 1/3 N through FYM + 1/3 N through vermicompost + 1/3 N through neem cake recorded significantly higher residual nitrogen in soil after the harvest of crop. Highest chlorophyll content was recorded under T2 which remained at par with T8 and T9. However, there was no significant affect on canopy temperature with different sources of nutrients. Treatment T2 (100% RDF) realized highest net returns (Rs. 32779 ha-1) and B:C (2.15) closely followed by T8.
