An experiment was carried out to study the response of integrated nutrient supply (IPNS) on yield traits of maize e.g., total number of cobs in net plot, cob weight (q ha−1), number of rows/cob, number of grains/row, number of grains/cob and 1000 grain weight on average basis ranged from 57.07 to 71.67 thousand ha−1, 38.85 to 60.62 q ha−1, 13.47 to 17.16, 32.70 to 35.07, 415.29 to 566.93 and 170.70 to 224.86 g, respectively. The values of these parameters recorded highest under treatment T3 (FYM + Chem.) which were at par with T8 (Azotobacter + Rhizobium + PSB + FYM + Chem.) and these were significantly superior to rest of the treatments during both the years of study. Grain yield 33.13 to 52.56 q ha−1, stover yield 40.32 to 60.76 q ha−1, total biological yield 73.44 to 113.32 q ha−1, grain: strover ratio and harvest index of maize on an average ranged from 0.82 to 0.87 and 45.11 to 46.38%, respectively. In these parameters, significant increase was recorded in the treatments received organic, inorganic and bio-fertilizer sources of nutrients in combined form.
