Yield attributes of wheat (Triticum aestivum L.) varieties as influenced by nitrogen management under of late sown condition

Abstract

A field experiment was carried out at Agronomy Research Farm of Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during rabi season of 2012-13 to study the influence of different nitrogen management on yield attributes of wheat under late sown condition. There were twenty treatment combinations consisted of five doses of nitrogen (90 kg N ha-1, 120 kg N ha-1, 90 kg N ha-1 + 25% N through FYM, 120 kg N ha-1 + 25% N through FYM, 150 kg N ha-1) and four varieties of wheat (HUW-234, HP-1633, NW-1014 and Raj-3077). The experiment was conducted in Randomized Block Design (R.B.D.) factorial with three replications on silt loam soil having low organic carbon (0.38%), nitrogen (203 kg ha-1), medium in phosphorus (15.25 kg ha-1) and potassium (265 kg ha-1). The yield attributes viz., ears per meter row length, ear length (cm), grain ear-1 and grain weight ear-1(g), 1000-grain weight (g) were found maximum under the treatment 120 kg N ha-1 + 25% N through FYM. Among the varieties HUW-234 being at par with NW-1014. 1000-grain weight (g) was not influenced significantly due to varieties.
