Abstract: The field experiment was conducted during kharif season of 2023 at Crop Research Farm, Department of Agronomy. The experiment was laid out in a Randomized Block Design with ten treatments which have replicated thrice. The treatments details are as fallows T1: Farm yard manure 5 t/ha + Panchagavya 3%, T2: Farm yard manure 5 t/ha + Jeevamrut 5%, T3: Farm yard manure 5 t/ha + Cow urine 2%, T4: Poultry manure 1 t/ha + Panchagavya 3%, T5: Poultry manure 1 t/ha + Jeevamrut 5%, T6: Poultry manure 1 t/ha + Cow urine 2%, T7: Vermicompost 2 t/ha + Panchagavya 3%, T8: Vermicompost 2 t/ha + Jeevamrut 5%, T9: Vermicompost 2 t/ha + Cow urine 2%. Application of Vermicompost 2 t/ha + Panchagavya 3% (Treatment 7) recorded highest plant height (82.26 cm), no. of nodules (6.33 per plant), maximum plant dry weight (20.96 g/plant), crop growth rate (10.30 g/ݑš2/day), relative growth rate (0.0269 g/g/day), pods per plant (21.67), pods per plant (5.07), seed per pod (8.11), seed index (21.67), seed yield (1.79 t/ha) stover yield (3.42 t/ha), and harvest index (34.21)%. The same treatment also recorded maximum gross return (84130 INR/ha), net return (47930 INR/ha), and benefit cost ratio (1.32).
