ABSTRACT
Considering the importance of organic farming and growing demand for organically produced foods, field studies were conducted during the kharif seasons of 2013 and 2014 at College of Agriculture, Vellayani, Thiruvananthapuram, Kerala to develop an organic nutrient schedule for direct seeded rice. The yield attributing characters such as spikelets panicle-1, filled grains panicle-1 and panicle weight were found the highest when 100% RDN (90 kg N ha-1 ) was applied through organics (FYM @ 5 t ha-1 + 1/2 RDN by FYM + 1/4 RDN by VC+ 1/4 RDN by NC) compared to INM even though there was a reduction in grain yield by 13-15%. Results of the study also indicate that application of 75 % RDN produced on par yield with 100 % RDN through organic nutrition in both the years. Though the cost of organic production was 15-27% higher, the reduction in net income was only 6-14% than INM.
