Crop Response to Nitrogen Fertilizers in Sharkia Governorate

Egypt has a total cropped area of 5.86 million faddans, out of which about 82% under food production. Among 75% food grains, wheat occupies the most important place and is grown on about 1.40 million faddans (32%), 12 percent of the total in Sharkia Province (168,971) faddans. In Egypt, wheat grain production which is around 1.54646 million tons is not sufficient in food production. The major factors responsible for such decrease in food production, has been the low consumption of chemical fertilizers. The Egyptian agricultural system has the potential to absorb a sizable increase in fertilizer consumption and thus to assist in augmenting agricultural production. Soil nitrogen and fertilizer nitrogen are two sources of the nitrogen for wheat growth. Under arid conditions, as in Egypt, organic matter is decomposed rapidly due to high temperature. The soils are very often low in organic nitrogen.Therefore, nitrogen fertilizers could play an important role in increasing wheat yielde. this study was undertaken to investigate the effect of different forms and rates of nitrogen fertilizer on the yield and nutrients content during growth stages of wheat grown in sharkia soils.
