| Abstract : A field experiment was carried out in the 2012-2013 winter season, experiment was designed as Randomized Complete block design R.C.B.D in Split plot arrangement ( split - plots ) and three replications,Water stress occupied main plots, which included (full irrigation without skipping , water stress by skipping irrigate in tillering stage and water stress by skipping irrigate in grain filling stage) ,Whereas (P) fertilization occupied the secondary plots, which included two levels are (0,100) kg P. h ˉ ¹. The results showed that water stress at the stage of tillering causse a significant decrease in the number of spikes per square meter , the number of grains per spike , grain yield , biological yield , water-use efficiency for the grain yield and biological yield, while water stress in the stage of grain filling causes a significant decrease in weight of 1000-grain cereals, grain yield , water-use efficiency for the grain yield .Phosphate fertilizer increased the means of all traits (number of spikes, number of grains, 1000-grain weight, grain yield, biological yield and water-use efficiency) as compared to the control treatment. | ||
