Influence of Irrigation and Nitrogen Level on the Yield of Wheat
Abstract:
An experiment was conducted during the period from November 2001 to April 2002 to determine the optimum irrigation time and nitrogen level of wheat. Highest grain yield (3.71 t ha-1) was obtained with three irrigations at crown-root initiations (CRI)+maximum tillering (MT)+grain filling (GF) stages which was identical with two irrigations at crown-root initiations (CRI)+maximum tillering (MT) stages and at crown-root initiations (CRI)+grain filling stages. The highest grain yield (3.61 t ha-1) was obtained from 120 kg N ha-1 which was followed by 100 kg N ha-1 treatment and the lowest grain yield (2.81 t ha-1) was recorded under 40 kg N ha-1 treatment. No significant effect was observed on yield due to interaction of irrigation and nitrogen level. The highest grain yield (4.33 t ha-1) was found by three irrigation at crown-root initiations (CRI)+maximum tillering (MT)+grain filling (GF) with 120 kg N ha-1. However, grain yield of wheat was significantly influenced by irrigation and nitrogen level but not due to interaction of irrigation and nitrogen level.
