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. A field experiment was conducted at research farm of Birsa Agricultural University, Jharkhand with an objective to evaluate yield attributes, yield and economics of different rice varieties under organic farming in the region of Jharkhand. The soil of experimental plot was sandy clay loam in texture having average carbon (6.16 Kg/ha), nitrogen (254.78 kg/ha), phosphorous (39.59 Kg/ha) and potassium (208.26 Kg/ha) with soil pH 6.04. Field experiments were carried out using randomized block design replicated thrice involving twelve treatments with twelve rice varieties viz. BVD 203, Birsa Dhan 201, Birsa Vikas Sugandha 1, BVD 110, Sahbhagidhan, Birsamati, Anjali, Lalat, M.T.U. 1010, Akshay, Pusa Sugandha and Naveen. Result of the study revealed that maximum no. of effective tillers per m2 (256.67) was observed in Birsamati, no. of grains per panicle (113.00) was observed in Lalat, no. of unfilled grains per panicle (37.67) was observed in Sahbhagidhan, panicle length (26.80 cm) was observed in Lalat. M.T.U. 1010 recorded the highest 1000 grain wt. (24.09 g), panicle wt. (3.95 g), grain yield (40.22 kg/ha), straw yield (62.96 kg/ha), harvest index (39.01%), gross return (93669 â‚¹/ha), net return (56057 â‚¹/ha) and B:C ratio (1.49) can be recommended under organic rice production in the region of Jharkhand (India).
