Determining the Effect of Biofertilizer and Phosphorus on Yield and Nutrient Uptake by Black Gram (Vigna mungo L.)

A field experiment was conducted at experimental farm, Department of Agronomy, Faculty of Agriculture and Veterinary Sciences, Mewar University Gangrar, Chittorgarh (Rajasthan) during Rabi season of 2023-24 to effect of Biofertilizer and Phosphorus yield and nutrient uptake by of black gram variety “Pratap Urd-1‟ was used in this study. The result revealed that the maximum yield parameter such as number of pods per plant (29.75), number of seed per pod (7.78), grain yield (12.12 q/ha), straw yield (27.02 q/ha) with application of T10-50 kg P2O5 ha-1 + PSB + VAM. The maximum nitrogen content and uptake in grain and straw (3.64, 1.52 % and 44.12, 41.07 kg/ha), phosphorus content and uptake (0.32, 0.30% and 3.38, 8.11 kg/ha) and potassium content and uptake (1.92, 1.74% and 23.47, 47.01 kg/ha) were recorded with T10-50 kg P2O T9-50 kg P2O5 ha-1 + VAM 5 ha-1 + Phosphorus solubilizing bacteria + Vesicular arbuscular mycorrhiza.
