A field experiment was conducted during the Kharif season of the year 2016-17, 2017-18, 2018-19 and 2019-20 at Research farm, Organic Farming Research Centre, Sher-e- Kashmir University of Agricultural Sciences and Technology of Jammu, Chatha to find out most suitable crop establishment methods on growth and productivity Organic Basmati rice in Jammu region. The System of Rice Intensification (SRI) practices have been developed in order to increase the production and quality of rice. Based on SRI practices the rice seedlings are transplanted at the young ages, 10-12 days old with just 2 leaves and carefully planting of just one seedling per hill and space the hills optimally widely in a square pattern of 25×25 cm for better usage of water, sunlight, minerals, space, nutrient, weeding and pest management within shallow depth (1-2 cm) in the moist soil condition. The results revealed that application of Vermicompost 3.0 t ha-1 followed by FYM @ 8 t ha-1 recorded maximum yield (37.77 and 36.94 q ha-1 respectively). It can be attributed due to improved growth parameter like plant height, tillering, root number, number of effective tillers per hill, days to flowering and harvest index of organic basmati rice (Basmati 370), increased panicle production and filled grains panicle-1in both treatments. In addition, SRI was found effective in minimizing pest and disease incidence, shortening the crop cycle, and improving plant stand. The improved panicle characteristics, lower plant lodging percentage and higher harvest index that ultimately led to comparable grain yields of organic basmati rice. Under organic management with SRI Basmati 370 responded better to nutrient applications with yield superiority of 35%. The maximum additional net return due to SRI technology of Rs 92534 /ha was recorded under Vermicompost 3.0 t ha-1, which was at par of FYM @ 8 t ha-1 Rs 89646/ha.
