The Effect of Irrigation Intervals Scheduling and Nitrogen and Zinc Content on Wheat Yield and Yield Components in Drought Stress

Abstract

Abstract In order to evaluate the effect of irrigation interval on yield and quantitative-qualitative characteristics of bread wheat, splited plot experiment in randomized block with four replications in the 2010-11 crop years was conducted in the research field of Islamic Azad University of Gonabad. A number of 7, 9 and 10 days irrigation treatments formed the main factors of test, and spraying and non-spraying of nitrogen and zinc were considered as subfactor of test. The results showed that the effect of ir…
