Abstract
Field experiment was conducted at Norman E. Borlaug Crop Research Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar during 2008-09 to study the effect of integrated nutrient management on wheat under rice-wheat cropping system in a Mollisol.Twelve treatments were replicated twice in split plot design with 12 main and 2 sub plots. Plant height, number of tillers, wheat grain and straw yield were noted. Nutrient content (N, P, K & S) in wheat and nutrient uptake (N, P, K & S) by wheat were determined. Partial replacement of N through FYM and wheat and moong straw resulted in significant improvement in nutrient concentration as well as their uptake and wheat yield. The treatments with 100% N or NPK and 50% N applied through moong straw were better than all other treatments and moong straw proved the best among organic sources of N studied in respect of its effect on wheat yield & nutrient status in plant.
Key words : INM, rice-wheat cropping system, FYM, moong straw, wheat straw.
