Effect on Yield, Attribute Character and Economics of Various Treatment in Wheat (Triticum aestivum L.) Crop

Abstract

A field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during Rabi season of 2014-15 to study the response of late sown wheat varieties to doses of nitrogen application. Eighteen treatment consisted of six doses of nitrogen (0, 40, 80, 120, 160 and 200 kg N ha-1) and three varieties of wheat (PBW-373, HD-2327, and NW-1014). The experiment was carried out in Randomized Block Design R.B.D. (factorial) with three replications on silt loam having low organic carbon (0.37%), nitrogen (194.25 kg ha-1), medium in phosphorus (15.25 kg ha-1) and potassium (250.25 kg ha-1). All the growth and yield parameters increased significantly with increasing nitrogen doses up to 200 kg ha-1. The maximum net return (Rs. 40712ha-1) was obtained at 160 kg N ha-1 with NW-1014 and B:C ratio 1.19 followed by same variety at 120 kg N ha-1. Thus it may be concluded that application of 160 kg N ha-1 proved appropriate levels of nitrogen for exploration of the yield potential of the late sown wheat varieties. Among the varieties NW-1014 was found the most suitable for cultivation under late sown condition for Northern East Plain zone.
