Abstract
The field experiment was carried out in the Experimental Farm of the Desert Research Center at Ras Sudr Region, South Sinai Governorate, during the two successive summer seasons of 2008 and 2009 to study the effect of the combinations among three levels of N, P, K (100%, 80% and 60% of recommended dose) with nitric or phosphoric acids individually or mixture of them to minimizing the harmful effects of salinity on growth, yield and fruit quality of sweet pepper plants. The results suggested that the effect of the highest level of N, P, K (100%) combined with mixture of nitric and phosphoric acids gave the most vigorous plants expressed as plant length, fresh and dry weight of plant and dry matter content of plant, in both seasons. Moreover, it produced the highest fruit yield and gave, the best physical properties of fruits, i.e., fruit length, weigh and number of fruits/plant, as well as the best values of total chlorophyll, vitamin C, N, P, K of leaves tissues. On the other hand, it decreased Na and Cl concentrations.
