Abstract
The study was carried out in Sewa Oasis, Egypt, in Tegthierty area whose soil is loamy sand in texture. Two field experiments were carried out depicting the application of three N levels in three methods namely soil, foliar, or combinations of both methods. The application of N via soil or foliage separately was on the purpose of exposing the effects of such routes in a clear cut as being not affected by the other levels or routes. These treatments were assessed in two successive seasons. Wheat variety Sakha 93 was the test plant. The aim of this study was to approach the goal yield of wheat by using the least possible N level via either soil, foliar, or both. It was found that all N fertilization levels and methods proved to be significantly better than the control treatment regarding wheat grain, straw, and biomass yields, growth parameters, and NPK uptake in both plant parts, as well in both seasons of study. The best combination treatment was found to be the integrated soil and foliar application of fertilizer N at the highest rate.
