The effect of integrated use of chemical fertilizers (NPK) and farm yard manure (FYM) on grain yield, straw yield, grain protein content and net profit of wheat was carried out in the Experimental Farm of the Faculty of Agriculture, South Valley University at Qena during two seasons on a sandy soil. The recommended NPK and FYM were applied alone and in various combinations among them. A randomized complete block design, with three replications, was used in this study. Treatments significantly affected grain and straw yields, as well as grain protein content. The highest values of previous traits were obtained from treatment T4 (50% chemical NPK + 6 tons FYM per ha). Also, this treatment gave the maximum return and net profit per ha compared with the other treatments. Therefore, integrated plant nutrient supply system could help in meeting the goals of balanced fertilization and reduce environmental pollution.
