Abstract: The field experiment was carried out at Department of Soil Science, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad, India during kharif season (July to November) of 2015-16. The experiment was laid out in 3×3 factorial randomized block design with 9 treatments in three replications. It was observed that the best yield attributes characters in treatment T8 (N:P:K:Zn 120:60:60:20 kg ha-1 + FYM 10 t ha-1: Azotobacter 200 gm/10kg seed) in respect to different day’s intervals i.e. 30, 60 and 90 days after sowing (DAS). Plant height was 65.12, 165.86 and 169.55 cm found to be significant at 60 and 90 DAS but non-significant at 30 DAS, leaf length were 21.55, 52.34 and 54.90 found to be significant at 30,60 and 90 DAS, no. of leaves plant-1 were 7.78, 11.78 and 12.89 found to be significant at 60 and 90 DAS but non-significant at 30 DAS, Highest no. of grains was found in T8 (N:P:K:Zn 120:60:60:20 kg ha-1 + FYM 10 t ha-1: Azotobacter 200 gm/10kg seed) which was 308.55 found to be significant. Highest cob length was found in treatment T8 (N:P:K:Zn 120:60:60:20 kg ha-1 + FYM 10 t ha-1: Azotobacter 200 gm/10kg seed) which was 17.08 found to be significant. T8 (N:P:K:Zn 120:60:60:20 kg ha-1 + FYM 10 t ha-1: Azotobacter 200 gm/10kg seed) found highest seed yield (q ha-1) and test weight (g) which were 51.00 and 220.67 respectively found to be significant. Highest dry weight (g) found in T8 (N:P:K:Zn 120:60:60:20 kg ha-1 + FYM 10 t ha-1: Azotobacter 200 gm/10kg seed) which was 176.55 found to be significant. Highest B:C ratio (1: 2.43) was recorded in T8 (N:P:K:Zn 120:60:60:20 kg ha-1 + FYM 10 t ha-1: Azotobacter 200 gm/10kg seed). However, since these findings are based on one year experiment and therefore, further research may be conducted to substantiate it under Allahabad agro climatic conditions
