Abstract: A field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (Uttar Pradesh) during the zaid season of 2016. The experiment comprised of nine treatments viz. T₁ : Control, T₂ : 20 kg P₂O₅ha^-1, T₃ : 40 kg P₂O₅ha^-1,T₄ : 60 kg P₂O₅ha^-1,T₅ : 80 kg P₂O₅ha^-1,T₆ : 20 kg P₂O₅ha^-1+ PSB,T₇ : 40 kg P₂O₅ha^-1 + PSB,T₈ : 60 kg P₂O₅ha^-1 + PSB,T₉ : 80 kg P₂O₅ha^-1 + PSB tested in Randomized Block Design and replication three times. The basic information, on the physico-chemical properties of the soil indicated that the soil of the experimental field was classified as silty loam which was low in organic carbon, nitrogen and phosphorus and medium in potassium. The crop recorded normal recommended cultural practices and plant protection measures. Results revealed that all the growth, yield attributes and quality increased significantly under the integrated treatment (80 kg P₂O₅ha^-1 + PSB). The growth characters viz., plant height, leaf area index, dry matter accumulation and number of branches plant^-1 and yield attributes like number of pod plant^-1, number of grain pod¹, 1000 - seed weight (g), biological yield, seed yield, stover yield (q ha^-1), harvest index (%) and NPK uptake of mung crop. On the basis of economics of different treatment, the maximum gross returns (Rs. 72371.00 ha^-1), net returns (Rs. 50873.00 ha^-1) and B: C ratio (2.37) was recorded under treatment (P + PSB) for mung crop.
