The wheat variety HD-2967 was used. The treatments were T1: CONTROL, T2: 100 % NPK, T3: 100 % NPK + 5 ton FYM, T4: 100 % NPK + PSB + Azotobacter, T5: 125% NPK + PSB + Azotobacter + 5 ton FYM, T6: 100 % NPK + S40, T7: 100 % NPK + Zn5, T8: 100 % NPK + S40 + Zn5, T9: 100 % NPK + S40 +Zn5 + Fe10, T10: 100 % NPK + S40 + Zn5 + Fe10 + Azotobacter + PSB + 5 ton FYM, T11: 125 % NPK. Observation were recorded on growth character, yield attribute, grain and straw yield, nutrient concentration and uptake in grain and straw to find out the total nutrient absorption for a particular treatment. Results showed that plant growth, yield contributing characters, grain and straw yield, nutrients uptake, crop quality and number of bacteria, fungi and actinomycetes were significantly increased in treatments over control. The lower value of control 18.87 q ha-1 grain yield, 29.15 q ha-1 straw yield, N (1.53 % and 0.32 %), P (0.31 % and 0.13 %), K (0.84 % and 0.34 %), S (0.11 % and 0.14 %), Zn (31.35 ppm and 8.45 ppm) and Fe (43.29 ppm and 25.34 ppm) nutrient concentration in grain and straw and total nutrient uptake N (37.98 kg ha-1), P (9.55 kg ha-1), K (30.69 kg ha-1), S (7.84 kg ha-1), Zn (83.84g ha-1) and Fe (155.84 g ha-1) and quality in terms of protein (9.53 %), lysine (3.10 g/16gN) and methionine (1.11 g/16gN) and the best treatments of 100 % NPK + S40 + Zn5 + Fe10 + Azotobacter + PSB + 5 ton FYM gave 49.27 q ha-1 grain yield, 114.61 q ha-1 straw yield, N (112.64 kg ha-1), P (35.87 kg ha-1), K (195.03 kg ha-1), S (33.32 kg ha-1), Zn (289 g ha-1) and Fe (522.33 g ha-1). This treatment have the highest B : C ratio. Indicating that the yield and quality of the crop could be improved considerably in the latter over the former treatment. Thus it was inferred that application of integrated plant nutrient was useful for high yield and quality and for improvement in soil fertility.EnglishThesis
