This work was held in South Port Said in the growing season 2015-2016 to study the effect of the use of organic manure and mineral nitrogen fertilization on the production of sugar beet (Beta vulgaris L.) in a salt affected soil. Thirty four different treatments were performed on sugar beets between organic manure, mineral N fertilization and mixture between them .The growing plant parameters were recorded in terms of root yield (tons/fad) and total sugars percent , the best results were obtained using mineral nitrogen, the second treatment (T280 kg fed), because it exceeded the total sugar production. Samples of plants were analyzed after harvest that included estimating nitrogen concentrations. Where the results showed a response in most of them for nitrogenous additives and organic manuring.
