Abstract
This study was performed at Al-Isihaki date palm station attached to the General Date board/Ministry of Agriculture during 2012 season on three date palm cultivar White Farith, Saeef plant, and Alhilaly. Number and length Leaves and number of leaflet, root number and length, chlorophyll contents. 63 homogenized growth offshoots, grown on square system 5 m X 5 m were selected. The First chemical fertilization applied on march15, 2012, the second on June 15, 2012, and the third on September 15, 2012 .The study included 7 fertilizer treatments in addition to the comparison treatment. All the readings were collected at February 15, 2013 to confirm the results after one year. The experiment was designed on the split plot design and the varieties as main factor while other treatments as secondary factors. Three varieties and seven treatments the addition was calibrated to be N of 68, 136, and 204 gm, P of 9, 18, and 27 gm, and K of 30, 60, and 90 gm. The leafy fertilizer was high nitrogen 21% N, 0% P, and 0% K , equal amount at 20% P, and 20% K and Potassium high fertilizer 15% N, 10% P, and 30% K at 5000 mg/liter -1, with three replicates for each treatment. The differences were compared between averages based on LSD at the possibility of 5%.The fertilizers treatment was applied three dates march , Jun and September .The results of the study showed significant results of white Faith variety over other two varieties (Saeef plant and Al hilaly) in the vegetative growth as width of leaflet, leaf length, and leaves number. While Saeef plant significantly showed dominance over other two varieties in root number. The variety of Al hilaly dominated also in number of fronds and leaves contents of chlorophyll . All treatment showed a significant effect on vegetative growth with concentration increase compared to the comparison treatment . The Third treatment (204gm N, 27gm P, 90 gm K)(T3) of fertilizers used as the leaves number was 16.73 leaves, with length of 161.95 cm, leaflet length of 29.00 cm and width of 2.78 cm . While roots number was 34.87, 60.25 cm of the length, then 6.98 mm/root of width. Leaf contents as chlorophyll of 62.03 SPAD. The combination between varieties and chemical treatment resulted in significant increase in the vegetative growth average; the combination of variety Saeef plant and third treatment (V2T3) gave highest averages of vegetative growth as leaf length, leaflet length and width, root length and width, with the combination between varieties Saeef plant and Al hilaly of third treatment. The results of variety Al hilaly combined with third treatment (V3T3) gave a significant dominance in vegetative growth root number, chlorophyll contents.
