The Effect of Different Amount of Irrigation Water and Optimum Nutrition on Some of the Growth Characteristics of Three Wheat Cultivars

In order to study the effect of various irrigation water levels and fertilizers on water use efficiency, yield and seed protein content, a two year field experiment was conducted in agricultural and natural resources research station of Broujerd. Experiment was carried out in a split split plot design in three replicate. Main plot was involved three irrigation water levels (I0=4000, I1=5000, I2=6000 m3) and three levels of fertilizer including F1=NPK+M, F2=NPK+1.3M and F3=NPK + 0.7M are allocated to sub plot. M means microelement consumption including iron, zinc, manganese, copper and boron. Sub sub plot was allocated to three wheat cultivar including Marvdasht, M -75-7, M -75-10. Two years results of studied treatments showed that highest seed yield is related to M-75-10 cultivar; highest water use efficiency is related to Marvdasht cultivar and highest protein content is related to M-75-7 cultivar.
