Online published on 24 December, 2014. Abstract Field experiment was conducted during wet seasons to study the effect of organic nutrient management on dry matter partitioning, growth and productivity of scented rice cv. Birsamati. Pooled analysis of two years data revealed that scented rice grown with 100:21.8:20.8 Kg NPK ha−1 having higher growth parameters produced maximum grain (3.95 t ha−1) and straw yield (5.55 t ha−1), net return ( 39,557 ha−1) and benefit: cost ratio (3.62), owing to higher value of yield attributing characters. Among various organic sources, use of green manuring @ 5 t ha−1 + FYM @ 10 t ha−1 was observed to be superior with maximum dry matter (1337.5 g m−2) at maturity and its partitioning into grain, 40% of the total dry matter in panicle, higher grain (3.28 t ha−1) and straw yield (4.35 t ha−1), net return ( 35,975 ha−1), benefit- cost ratio (2.61) owing to more number of panicles m−2(289.5), maximum grains panicle−1 (88) and bolder grains (1000 grain weight-22.12g), higher crop growth rate compared to rest of the organic treatments Top Keywords Organic nutrient management, dry matter, scented rice.
