Response of Phosphorus and Biofertilizers on Growth, Yield Attributes and Economic Indices of Black Gram (Vigna mungo L. Hepper)

Field experiment was conducted during the kharif season of year 2019 to study response phosphorus and biofertilizers on growth, yield attributes economic indices black gram (Vigna mungo L. Hepper). The initial soil parameter status were pH 4.6, OC 1.16%, medium in available N (256.99 kg ha-1), low P (18.95 ha-1) K (212.56 ha-1). well drained sandy loam texture laid out Factorial Randomized Block Design with three replications. treatments consisted four levels i.e. 0, 20, 40, 60 P2O5 ha-1 biofertilizer uninoculated, Rhizobium, PSB, Rhizobium + PSB. Among various treatment sources, dual inoculation seeds along PSB significantly increased growth such as plant height, population, Leaf Area Index (LAI), number leaves plant-1, branches Crop Growth Rate (CGR), pods plant-1 (30.72), pod length (4.68 cm), pod-1 (7.20), seed (1120.35 stover (2401.54 harvest index (31.80 %) over rest treatments. Results further indicated that a higher net return ₹ 39,811 B:C ratio 1.45 also observed application
