It is clear that there is a great shortage of wheat production in Egypt. Here also water resources and cultivated area are limited. This reflects the size of the problem. Production of wheat in newly reclaimed sandy soils may be solving these problems. A field experiments were conducted out to study the effect of soil moisture and forms of P fertilizer on uptake of P by wheat plant as well as the yield production under drip irrigation system. Phosphorous uptake by wheat plants during the growth period was significantly (p<0.05) affected by soil moisture (amount of irrigation water) and the source of P. At early beginning of growth period (45 day after wheat planting), wheat plants received P as Mono ammonium phosphate (MAP) and Urea-phosphate (UP) taken up more P comparing to the other P sources, while 75 days after planting and later on wheat plants fertilized with UP and Phosphoric acid (PA) contained higher amounts of P
