Abstract: In Kashmir valley the shortage of labour and water are pressing farmers to explore the alternatives of conventional transplanting. Use of organics being an important component of SRI, but its availability and costs inhibit farmers from adoption of this method. Hence, impacts of other alternatives in SRI need to be assessed. A field experiment was conducted during kharif seasons of 2013-2015 at SKUAST-K, Khudwani, Jammu and Kashmir, to evaluate the performance of three rice establishment methods and six nutrient management practices on rice yield. The data revealed that crop establishment methods and nutrient management practices significantly influenced the grain yield of rice. SRI method of crop establishment had resulted in significantly higher rice grain yield over other two methods DSR and conventional transplanted rice. Among the methods of nutritional management, application of 150% RDF produced significantly higher grain yield compared to other practices. Average grain yield increase with SRI was to the tune of 8.9 per cent over DSR and 4.4per cent over TPR (SRI- 6.15 t ha-1, DSR- 5.63 t ha-1 and TPR 5.89 t ha-1). Application of 150% RDF or integrated nutrition involving RDF (50% fertilizers + 50% organic manures) proved promising for the improvement of rice productivity.
