Abstract:
A field experiment was conducted during Kharif season 2015 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). Twelve treatments comprising 100% NP, 100% NPK, 100% NP + 125% K, 100% NP + 150% K, 125% NPK, 150% NPK, 100% NP + Crop residue, 100% NP + FYM, 100% NP + SPM, SSNM, SSNM-K and SSNM+K were replicated thrice in a randomized block design. The data on growth, yield and its contributing traits were calculated on plot area basis (15 m²), whereas content and uptake of nutrients at various stages along with available N, P, K, S, Zn, B and Fe as well as availability at surface, sub surface and potassium dynamics was recorded as per the standard procedure. The experimental results revealed that Application of SPM along with the recommended dose of N, P improved organic carbon of soil. Therefore, application of 150 % RDF (100:60:60 kg NPK) proved to be better for achieving higher yield and maintaining the nutrient status of soil. Although the yield was high in 150% NPK but it did not differ from SSNM therefore. The practice of SSNM is found better for sustainability of crop yield and soil health.
