| Abstract | ||
| The study was carried out at a private orchard , in Al-Hartha region –Basrah, at the beginning of (April) until (August) for the growing season 2010, the purpose of knowing the effect of spraying with NPK concentration (2 and 2.5) % and urea concentration (1) % on the leaves in the pracentage of Ripening and some chemical characteristics of Date Palm Khidrawi cultivar, the results showed superiority treatment spraying with NPK concentration of 2.5% before spathes opening and at the early stage of kammri significantly increased total soluble solids and total sugars and reducing sugars and dry matter and pracentage of fruit ripening compared with other treatments, while treatment spraying with NPK concentration of 2.5% before spathes opening and at the early stage of kammri led to a decreace in Water content of fruit significantly. The results showed that there are no different significances with the treatment of spraying with urea concentration of 1% before spathes opening or in the early stage of kammri with the control treatment in the concentration of total soluble solids and total sugars and reducing sugars and dry matter of fruits. | ||
