Effect of wheat varieties, moisture regimes and nutrient supply system on growth and yield under late sown condition in eastern U.P

Abstract

A field experiment was conducted at the Agronomy Research Farm of Narendra Deva University of Agriculture & Technology, Kumarganj Faizabad (U.P.) during rabi season of two consecutive years of 2012-13 and 2013-14 with eighteen treatment combinations consisted of three wheat varieties, i.e.V1(NW-2036), V2(PBW-373) and V3(HUW-234) and two moisture regimes, i.e. M1(irrigation at 0.8 IW/CPE ratio) and M2(1.0 IW/CPE ratio) in main plots and three nutrient supply system, i.e. F1(100% RDF through chemical fertilizers 150:60:40 NPK kg ha-1), F2(50% RDN+ 50% N through FYM and F3(50% RDN+50% N through neem cake) in sub plots. The growth characters like plant height (cm), number of shoots per meter row length, LAI, crop dry matter as well as yield attributes e.g. number of grains m-2, length of spike (cm), number of grains- spike-1 and weight of grain spike-1 were found significantly higher with variety PBW-373, moisture regime 1.0 IW/CPE and RDF at 150:60:40/NPK kg h-1 over rest of the treatments during both the years. The grain and straw yields were also followed the same trend as of growth and yield attributes during both the years.
