Effect of tillage, irrigation schedule and N- fertilization on barley the central zone of Uttar Pradesh

Abstract

The study was carried out in the Department of Agronomy of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur U.P. India, during rabi season of 2013-14. The treatments comprised of viz. 2 tillage, 3 Irrigation schedule and 2 Nitrogen fertilization in 12 treatment combinations, viz. T1+IR1+F1, T1+IR1+F2, T1+IR2+F1, T1+IR2+F2, T1+IR3+F1, T1+IR3+F2, T2+IR1+F1, T2+IR1+F2, T2+IR2+F1, T2+IR2+F2, T2+IR3+F1, T2+IR3+F2. The tillage was tried in main plots, irrigation schedule and nitrogen fertilization in sub plots in split plot design with 3 replication. The crop raised with recommended package of practices other than treatments. The 1.0 IW/CPE ratio irrigation level was produced highest in respect to growth attributes, yield attributes, grain yield 42.67 q ha-1, harvest index 38.73 percent, consumptive use 240.69 mm, water use efficiency 17.72 kg grain ha-1 mm, N content in grain 1.87 percent, N content in straw 0.33 percent, NUE 116.13 percent, net income 40899 Rs. ha-1 and benefit cost ratio 1.37, but reduced in 0.75 IW/CPE ratio and 0.5 IW/CPE ratio respectively.
