Effect of integrated nutrient management on growth and yield of basmati rice (Oryza sativa) through use of different organic manures and crop residues

The present investigation was carried out during the kharif season of 2018-2019 at the Student’s Research Farm, Khalsa College, Amritsar to evaluate the effect of integrated nutrient approach on growth and yield of basmati rice. The experiment was laid out in Randomised Block Design (RBD) with three replications each having different combinations of nitrogen i.e. Recommended nitrogen (RN), Farm yard manure (FYM), Press mud (PM), Berseem residue (BR) and Mustard residue (MR). The results revealed that the application of 100% RN led to more growth and yield contributing characters which increased grain yield by 70.18% over control, followed by 75% RN + 25% BR which produced 0.89 q/ha less yield than 100% RN that was equivalent to Rs. 2848/- but also saved 25% RN (or 22.5 kg urea). Thus, up to 25% recommended nitrogen can be substituted by berseem residue without significantly affecting the grain yield which is a major key concern for sustainable agriculture.
