Description The long-term experiment has been continuing at research farm of the Institute of Agricultural Sciences, Banaras Hindu University, Varanasi since 1985-1986 on rice-wheat cropping system. Field experiment was conducted during Rabi (winter) season of 2016-17. The experiment was conducted with 12 treatments replicated three times employing randomized block design. Out of which 6 treatments comprised with integration of organics with inorganic fertilizer supply system, 4 treatments included only chemical source of nutrients, one was farmer’s practices and one control. The organic sources of nutrients included were (i) Farm Yard Manure (FYM) (ii) Green manure (GM) Sesbania aculeata (dhaincha) (iii) Crop residues (CR) i.e. wheat straw. Chemical sources of nutrients were urea, diammonium phosphate, muriate of potash as per the treatments. The recommended level of N was partially substituted by 25% or 50% N either through FYM or wheat straw or green manure. The result indicated that highest N, P, K and S content and uptake in grain and straw was recorded in plots receiving 50% NPK+50% through FYM. Treatments which included organic matter along with chemical fertilizers showed higher concentration and uptake of nutrients (N, P, K and S). Concentration of nutrient elements in straw and grain increased due to effect of organic matter in case of N, P and K but remained almost unchanged in case of S. All the organic sources were at par for grain yield of wheat. Continued use of organics with inorganic fertilizers in an integrated manner could sustain yields of wheat and maintained adequate supply of nutrients.
