Abstract: Efficiency of irrigation method and application of organic amendments are concepts should be practiced in Egypt for saving part of irrigation water due to the limited water resources. A field experiment was conducted on a newly reclaimed loamy sand soil at the Experimental Farm of Ismailia Agriculture Research Station, Egypt during winter season 2013/ 2014, to study the effect of irrigation scheduling under sprinkler irrigation method with levels Ir1 (125% application of water from traditional amount), Ir2 (100% application of water at traditional amount) and Ir3 (75% application of water from traditional amount) with application of compost fertilizer at different levels Zero (L0), 5 tonfed-1 (fed is a local units is 4200m2) (L1), 10 tonfed-1(L2) and 15 ton fed-1(L3) on weight of 1000 grain (g), straw yield ton fed-1, grain yield ton fed-1, biological yield ton fed-1, harvest index, N%, N-uptake kg fed-1, and water productivity L.E/m3 of water under cultivation of wheat plant (Triticum aestivum L.) Giza 168 cultivar. Also, to assess and compare farm profitability of all tested variables. The obtained results revealed that compost application at the three levels increased significantly each straw yield tonfed-1, grain yield tonfed-1, weight of 1000 grain (g), biological yield tonfed-1, harvest index %, N%, N-uptake kg fed-1 and water productivity L.Em3 of water over the control treatment. The highest mean values for the studied parameters were recorded for compost application at level L3. On the other hand, the data indicated that the highest means values for 1000 grain weight, straw yield and grain yield were achieved with application of Ir2. At the same time, the difference of mean values for all parameters above mentioned between the amounts of irrigation water applied Ir1, Ir2 and Ir3 were insignificant. On the other site, the beneficial effect of all tested treatments was due to interaction between treatments L1*Ir2 or L1*Ir3 on weight of 1000 grain, straw yield tonfed-1, grain yield tonfed-1, (g), biological yield tonfed-1 and harvest index, N%, N-uptake tonfed-1 and water productivity L.Em3 of water. Therefore, data revealed that with application of treatments Ir3 about 25% irrigation water amount could be saved under applying compost at level 5tonfed-1 (L1) in loamy sand soil. These results were incorporated with the highest crop yield, water productivity and net income. Whereas, the data indicated that each one m3 of irrigation water consumed to irrigation wheat crop grown on loamy sand soil by interaction treatments Ir3 (saved 25% irrigation water from traditional water amount) *L1(5tonfed-1) was approximately profitably by 2.3LE pound for farmer. So, it can be concluded that the interaction between the treatments Ir3*L1 leads to rationalize as well as represents a solving for the problem of limited water resources and poor fertility in new reclaimed loamy sand soil in Egypt.
