A field experiment on green gram was carried out at the Instruction Farm of Invertis University Bareilly, Uttar Pradesh, India during kharif season 2024. The soil of the experimental field was sandy loam in texture, low in organic carbon and available nitrogen, but medium in available phosphorus and available potassium having slightly alkali pH (7.83) with an electrical conductivity of 0.294. The experiment was arranged in a randomized complete block design having 10 treatments viz; T₁- Control, T₂- Farm practices (DAP) @ 100 kg/ha, T₃- FYM @ 5 t/ha + DAP @ 100 kg/ha + Rhizobium @ 25 ml/kg seed, T₄- FYM @ 5 t/ha + DAP @100 kg/ha + Rhizobium culture @ 25 ml/kg seed + 2 % foliar spray of nano urea at 40 and 50 DAS, T₅ – FYM @ 5 t/ha + 100 kg/ha DAP + Rhizobium @ 25 ml/kg seed + N:P:K (18:18:18) @ 0.5 % foliar spray at 40 and 50 DAS, T₆- FYM @5 t/ha + DAP (18:46) @ 100 kg/ha + NPK Consortia @ 20 ml/kg seed, T₇- T₆+ Foliar spray @ 1.5 % Nano DAP at 40 and 50 DAS, T₈- FYM @ 5 t/ha + N:P:K (12:32:16) @ 100 kg/ha + NPK Consortia @ 20 ml/kg seed + NPK (18:18:18) @ 0.5 % foliar spray at 40 and 50 DAS + Biostimulant spray @ 625 ml/ha at 40 and 50 DAS, T₉- T₆ + foliar spray NPK (18:18:18) @ 0.5% at 40 and 50 DAS, T₁₀- FYM @ 5 t/ha + NPK (12:32:16) @ 100 kg/ha + Seed treatment with PSB @ 625 ml/ha+ foliar Spray of @ 1.5% Nano DAP at 40 and 50 + Fe₂So4 @ 0.5% at 40 and 50 DAS with three replication. The results noted that among the different nutrient management practices, application of FYM @ 5 t/ha + N:P:K (12:32:16) @ 100 kg/ha + NPK Consortia @ 20 ml/kg seed + NPK (18:18:18) @ 0.5 % foliar spray at 40 and 50 DAS + Biostimulant spray @ 625 ml/ha at 40 and 50 DAS had maximum plant height (61.10 cm), Number of branches/plants (6.16) and dry matter accumulation (18.23 g/plant) at harvest stage and significantly maximum pods/plant (14.5), pod length (8.3 cm), grains/pod (11.1), grain yield (13.5 q/ha), protein content (24.94 %) and protein yield (336.71 kg/ha) was recorded under the application. However maximum straw yield (25 q/ha), biological yield (38.1 q/ha) was recorded under the application of T₁₀ ( FYM @ 5 t/ha + NPK (12:32:16) @ 100 kg/ha + Seed treatment with PSB @ 625 ml/ha+ foliar Spray of @ 1.5% Nano DAP @ 40 and 50 + Fe₂So4 @ 0.5% at 40 and 50 DAS).
