<br/><br/> The current investigation was carried out during 2018 and 2019 seasons to study the effect of some fertilizer practices on yield, <br/>fruit quality and some mineral content of Khalas date palm grown in a private farm, Luxor Governorate, Egypt. Results showed that <br/>significant improved due to use slow release fertilizers as well as comparing total soluble fertilizers in terms of vegetative <br/>growth and nutritional status yield, bunch weight and fruit quality during both seasons. Using 600 g of N and 300 g of K via <br/>slow release fertilizers form had improved the growth and nutrient status of date palms as well as increase the fertilization <br/>efficiency. Also, it could be suggested that fertilizing by 60 to 75 of RDN and RDK via slow release fertilizers to improve <br/>the nutrient status of palm and gave the high bunch weight and consequently high yield/palm. Moreover, these fertilization <br/>treatments via slow release form gave high yield with good fruit quality compared with using 100% of RDN and RDK via mineral <br/>source during both studied seasons. On the light of previous results, it could be concluded that Fertilizing the palm <br/>by 60 to 75% of recommended doses of fertilization via slow release form to get high yield with good fruit quality. <br/>In addition, reduce the environmental pollution and increase the fertilization efficiency.<br/><br/>Keywords: Date palm, Nitrogen, Potassium, Slow release fertilizers, Yield, Fruit quality.<br/>
