ABSTRACT

During rabi, 2014 and 2015 at Agricultural College Farm, Mahanandi plant height of maize differed significantly due

to residual nutrients (main plots), nutrient doses ± crop residues (sub plots) at harvest. Leaf area index differed significantly with respect to nutrient doses ± crop residues at harvest during the second year, but interaction was not significant. There was significant influence of residual nutrients and nutrient doses ± crop residues on the dry matter production of maize. Significantly higher grain yield of maize was recorded in N₃P₂ and N₃P₃ in both the years with respect to residual nutrients. With respect to crop residues 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.
