Abstract: Field experiment was carried out in randomized block design with three replications and the treatment consisted of T1- control, T2- 100% RDF (120:60:40 kg ha-1 N: P2O5: K2O); T3ÂÂ- 75% RDF, T4- 75 % RDF + 25 % N-FYM, T5- 75% RDF+ Bio-fertilizer (Azotobactor); T6- 50% RDF + 50 % N-FYM, T7- (50 % RDF + 50 %N-FYM + PSB) and T8- 50 % RDF + Azotobacter + PSB. The treatment effect was compared based on yield, soil microbial population, nutrient content, protein content and nutrient uptake by wheat crop. The grain and straw yield (q ha-1), soil microbial population, nutrient content, protein content and uptake of nitrogen, phosphorus and potassium were maximum under T7, which was at par with T2, T4 and T6 and significantly superior over T1,T3, T5 and T8.The maximum grain and straw yield of wheat (41.90 & 60.65 q ha-1) was recorded with T7 which was significantly higher over than T1 (17.90 & 26.5 q ha-1), T3 (32.84 & 49.09 q ha-1), T5 (35.64 & 53.0 q ha-1) and T8 (34.80 & 51.75 q ha-1) while at par with T2 (41.60 & 60.33 q ha-1) T4 (39.55 & 57.0 q ha-1) and T6 (39.88 & 57.15 q ha-1). Maximum number of bacteria (39.38 X 107 g-1 soil) was recorded in T7 (50 % RDF + 50 % N-FYM + PSB) which was statistically at par with value recorded in T6 (50 % RDF + 50 % N-FYM). Treatment T7 and T6 were found significantly higher over rest of treatments while the minimum number (6.21 X 107 g-1 soil) of bacteria was recorded under treatment T1 (control). Similar trend also reported in the population of fungi and Actinomycetes in the soil after harvest of wheat crop.The maximum NPK content in grain (1.82, 0.50and 0.54 %) and in straw (0.55, 0.13 and 1.52 %) was observed under treatment T7 (50 % RDF + 50 % N- FYM + PSB) and minimum NPK content in straw (1.53, 0.43 and 0.50 %) and in straw (0.49, 0.10 and 1.43 %) was observed under treatment T1 (control).The maximum protein content (11.38 %) was observed in treatment T7 (50% RDF + 50% N-FYM + PSB) which was statistically at par with treatments T2, T4, T5 and T6 and significantly superior over treatments T1 (control), T3 and T8 while the minimum protein content (9.56 %) was recorded under treatment T1 (control). The maximum uptake of N (110.12 kg ha-1), P (28.83 kg ha-1) and K (114.81 kg ha-1) were observed under treatment T7 (50 % RDF + 50 % N-FYM + PSB), While minimum uptake of N (40.37 kg ha-1), P (10.35 kg ha-1) and K (46.85 kg ha-1) were observed under T1 (Control).
