EVALUATION OF WHEAT VARIETIES FOR HIGHER YIELD UNDER ORGANIC FARMINGMANOJ KUMAR, C.S. SINGH AND PRAMOD KUMARAbstract Organic wheat is being popular globally, due to continuous health awareness of the consumers towards organic food. In this context the demand for organic wheat is increasing to maintain high productivity. This study is focussed on the need to evaluate wheat varieties under organic farming. 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 wheat 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 wheat varieties viz. Raj 4250, GW 366, NW 2036, K 0307, K 9107, HI 1563, Raj 4229, DBW 14, WR 544, BG 3, HD 2733 and DBW 39. Result of the study revealed that among wheat varieties K 0307 showed maximum no. of spikes per m2 (336.67), total no. of filled grains (34.60), spike length (9.20 cm) and spike wt. (12.50 g) where as WR544 was recorded with maximum1000 grain wt. (45.47 g) and total no. of unfilled grains (9.33) was maximum in Raj 4250. Maximum grain yield (31.56 q/ha) and harvest index (42.80 %) was observed with K 0307 but the straw yield (45.16 q/ha) was maximum in GW 366. Gross return (62900`/ha), net return (23035`/ha) and B:C ratio (0.58) were found to be maximum in K 0307 and can be recommended under organic wheat production in the region of Jharkhand (India). |
