Abstract
This experiment was conducted during the growing season 2011 in AL-Falluja date palm research station province fellow general date board/Ministry of Agriculture. The aim of this study was to investigate the influences of the Nitrogen and potassium Fertilizers treatments on fruit characters (weight, length, diameter, volume , weight ,length, width seed and nutrients contents (leaves nitrogen content, carbohydrate, potassium ) on Khyara date palm at eight years age.Experiment was include four Nitrogen fertilizers levels (0 ,300 ,600, 900) g/tree , and four Patassium fertilizers levels (0, 200, 400, 600)g/tree .The experimental results showed : Nitrogen fertilizers level (900) g/tree was significantly on effect weight, length, diameter, volume , and (protein , Tannins content) and weight ,length, width seed and nutrients contents (leaves nitrogen content, carbohydrate, potassium )given highest weight fruit and total yield rates were 19.08 g/fruit , 53.75 kg/tree respectively . Than the control treatment losses average all parameter mentioned,gave weight fruit and total yield rates were 15.25g ,42.25 kg/tree respectively. Patassium fertilizers level (600) g/tree (K3) was significantly on effect highest superior in all parameter mentioned given total yield rate was (56.42) kg/tree, Than the control treatment losses all parameter mentioned given total yield rate was 41.58 kg/tree , The interaction between nitrogen fertilizer and the patassium fertilizer showed significant effect on highest superior in all parameter mentioned.The (N3K3) given highest on the yield total, These rate was, (61.67) kg/tree ,The control treatment given the losses average parameter mentioned. given yield total rate was 31.67 kg/tree.The content tannins fruit ,the treatment (N3) given losses average tannins content thase rate was 0.24% ,While the control treatment given highest . These rates was 0.30 % .The treatment (K3)given losses tannins content rate 0.25 % ,while control treatment given highest rate 0.29 %. The interaction (N3K3) treatment given loss tannins content rate 0.22% ,Than Than the control treatment highest given tannins content rate 0.35%
