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. (India) to evaluate the Potassium management for basmati rice (Oryza sativa L.) in intensive cropping system of Western Uttar Pradesh. The soil of the experimental field was well drained, sandy loam in texture, alkaline in reaction (pH 8.03), low in available nitrogen, medium in available phosphorus and available potassium with an electrical conductivity 0.29dSm-1. 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 in rhizosphere as well as potassium dynamics was recorded as per the standard procedure. The experimental results revealed that significant difference was found in growth attributes and yield attributing traits and also difference was found in uptake of nitrogen, phosphorus and potassium in rice. Among the different treatments uptake were maximum with the application of 150% NPK. However S, Zn, B and Fe uptake was highest in SSNM (Site Specific Nutrient Management) + K (Potassium). 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, quality and soil health.
