ABSTRACT

During rabi, 2014 and 2015 at Agricultural College, Mahanandi the yield attributes viz., number of cobs plant-1, cob length

and hundred grain weight of maize were not influenced significantly due to residual nutrients, nutrient doses ± crop residues and their interaction except number of grains cob-1. Graded levels of nitrogen exerted favorable influence on grain yield of maize. In the present study, the highest yield was obtained with the application of 250 kg and 300 kg N ha-1 in the previous season but the response to P levels was marginal. Significantly higher grain yield was recorded with F₂ (125% of F₁) which was however on par with F₄ (F₂ + Kharif crop residue incorporation) in both the years.
