The experiment was conducted at the Soil Science Research Farm of SHUATS – State University, Allahabad, U.P. The design of experiment used was 3x2x2factorial randomized block design having three factors viz. three levels of N (60, 90 and 120 kg N ha-1), two levels of FYM (0 and 10 t ha-1 FYM) and two Azotobactor levels (0 and 200 g per 10 kg seeds). Application of nitrogen @ 120 kg ha-1 gave the maximum cob length (18.00 cm), number of grains cob-1 (346.70), test weight (211.79 g) and grain yield (43.03 q ha-1) all these attributes were significantly higher over N1 (90 kg N ha-1) and N0 (60 kg N ha-1). Application of FYM @10 t ha-1 recorded the highest cob length (15.81 cm), number of grains cob-1 (326.40), test weight (205.57 g) and grain yield (36.34 q ha-1) which was significantly higher over no FYM application. Azotobactor @ 200 g per 10 kg seeds recorded cob length (15.38 cm), number of grains cob-1 (323.45), test weight (204.12 g) and grain yield (35.45 q ha-1) these were statistically superior over no seed treatment with Azotobactor. Combined treatment application (T11 = N2+F1+A1) of nitrogen 120 kg ha-1, 10 t FYM ha-1 and 200 g Azotobactor ha-1 was recorded significantly higher cob length (19.11 cm), number of grains cob-1 (362.87), test weight (25.20 g) and grain yield (45.58 q ha-1) these were statistically superior over rest of the treatment combinations.
