Wheat Productivity and Profitability Response to Nitrogen and Organic Sources under Full and Limited Irrigation Condition

Abstract

This field experiment was conducted to examine the result of organic and nitrogen sources on productivity and profitability of wheat under irrigation condition at the Agronomy Research Farm, The University of Agriculture Peshawar, Pakistan during (Rabi) season 2020-21. Organic sources at the rate of 10 t ha^-1 and nitrogen sources 140 kg ha^-1 were applied. The experiment was laid out in RCBD combined over irrigation using three replications (Each consist of 10 treatments). The treatments were comprised of one control plot (No OS and NS was applied), three OS (poultry manure, sheep manure and cattle manure each at rate of 10 t ha^-1) and three nitrogen sources (urea, ammonium sulfate and calcium ammonium nitrate at rate of 140 kg^-1). OS were applied accordingly to the plots one month before sowing. Fully irrigated field have total five irrigation was applied (after 7 days of sowing, tillering, heading, anthesis and grain filling stage) and the limited irrigated field only two irrigations were applied (one at tillering and the other is grain filling stage). Results showed that integrated use of PM (10 t ha^-1) and NS (140 kg ha^-1) significantly (P≤0.05) improved plant height, spikes m^-2, biological and grain yield. Results of the fully irrigated fields were higher than the limited irrigated fields. However, treated plots performance was better than the control
