Abstract
Field experiments were conducted at Research Farm, ICAR Sikkim Centre during two consecutive rainy sea- sons (kharif ) of 2012 and 2013 with the objective to select the efficient methods and rice (Oryza sativa L.) geno- types in terms of productivity, profitability and energetics for mid hill ecosystems of Sikkim Himalayas. The experi- ment was laid out in 3 times replicated split plot design, assigning 3 methods of rice production, viz. System of rice intensification (SRI), Integrated crop management (ICM) and Conventional planting (CP) to main plots and 6 rice genotypes, viz. Pusa Sugandh-2, Satyaranjan, Geetanjali, Rajendra Bhagwati, Krishna Bhog and Shahsarang in sub-plots. The results revealed that among the methods of rice production, significantly higher val- ues of all the yield attributes {productive tillers/hill, panicle length (cm), panicle weight (g), grains/panicle, 1,000 grain weight (g)} and grain yield (3.97 t/ha) were recorded with SRI followed by ICM and conventional method of planting. The increase in yield with SRI was 25 and 55% higher over the ICM and conventional planting, respec- tively. Gross returns, net returns, benefit: ratio and energy use efficiencies were also higher under SRI. Amongst the genotypes, maximum values of yield attributing characters and grain yield (4.15 t/ha) were recorded with the Satyaranjan which was significantly superior to other genotypes.
