Performance of modern cultivars in terms of yield under organic farming differs from that of conventional system. As the demand for organic rice is increasing, so to maintain high productivity, there is a need to evaluate modern high yielding rice varieties under organic farming systems. Field experiments were carried out using randomized complete block design involving fourteen rice (Oryza sativa L.) varieties including seven coarse and seven fine grain types with three replications under organic farming systems for three years (2013-2015). Results of the study revealed that higher yield attributes viz. grain weight panicle-1, 1000-grain weight, grain and straw yield as well as N, P and K uptake were recorded with coarse grain rice variety NDR-359. Among the fine grain rice varieties, Pant basmati-1 recorded higher grain yield as well as N, P, K and S uptake. So, coarse grain rice variety NDR-359 and fine grain rice variety Pant basmati-1 can be recommended under organic rice production in Tarai region of Uttarakhand (India).
