520			_aMinimizing mineral nitrogen fertilization through using 50% organic N (FYM) + 50% mineral N (urea) with Azotobacter chrococcum that fixed nitrogen as biofertilizer source were tested on mature Sewy date palm trees 12- years-old grown on sandy soil in private orchard located at El-Dakhla oasis, El-Wady El-Gedeed governorate. Leaf mineral content, yield and fruit quality especially fruit heavy metals, nitrate and nitrite contents and economic evaluation comparing with the traditional nitrogen fertilization (100% mineral nitrogen) were investigated. The obtained results showed that fertilizing palm with 50% organic N+ 50% mineral N+ biotreatments tended to increase N, P, K, Ca and Mg leaf contents. Moreover, treatments, 100% mineral or 50% organic N+ 50% mineral N+ biofertilizer significantly increased the yield kg/palm without non-significant differences between them in both seasons compared to other treatments. Both treatments of 100% organic or 50% organic N+ 50% mineral N+ biofertilizer improvement physical and chemical characteristics of date fruits.
