Abstract:
This Study was conducted in one of the orchards civil in Al - bradaah area in the province of Basra to the growing season 2014 on the date palm Phoenix dactylifera L. CV. Hillawi in order to study the effect of spraying fertilizer Gaton (seaweed extract) and concentrations (0, 2.5 0.5 ml) . L - 1 after inoculation and hold process sock both types manual Spikelet flowering (25% and 40%) of the number Spikelet flowering after inoculation and chemical thinning benzyl adenine (growth regulator) and concentrations (100 and 200) mg . L - 1 in addition to treatment comparison (no thinning), was carried out spraying the total vegetative and fruiting date palm of Gaton and benzyl adenine after inoculation two payments for the first five weeks and the second after ten weeks of the date of vaccination and the overlap between them in the physical and chemical characteristics and physiological and productivity of the date palm class Hillawi, which was Gaton factor with three levels and thinning five levels. Used Factorial Experiment According to Randomized Complete Block Design ( RCBD) with three replicates per treatment were compared according to the test averages less significant difference average (RLSD) at the level of probability (0.05). The results were as follows : - Results showed superiority of treatment overlap to spray in Gaton (5 ml . L - 1) and thinning benzyl adenine (200 mg . L - 1) significant superiority in fruit weight and gave the highest averages in terms of (7.55 and 7.05 and 6.450) g of the stages of Khalal and Ritab and Date on the relay and the weight of the seed reaching (1.380 and 1.290 and 1.280) g of the stages of Khalal and Ritab and Date on the relay and the weight of stromal layer where was (6.170 and 5.760 and 5.170) g of the stages of Khalal and Ritab and Date on the relay and also outperformed significantly in size and the length and diameter of the fruit and gave the highest averages reaching (7.60 cm 3 and 3.83 cm and 2.11 cm) on the relay to the stage of Khalal, (7.10 cm 3 and 3.86 cm and 2.00 cm) on the relay to the stage of Ritab, (6.56 cm 3 and 3.89 cm and 1.96 cm) on the relay to the stage of Date compared to transactions other under study. The results also showed superiority ofBtreatment overlap to spray in Gaton (5 ml . L - 1) and thinning manual (removal of 40% of the floral Spikelet) superior moral in chemical characteristics (T.S.S college faculty and sugars and shorthand) and gave the highest averages for the stages of Khalal and Ritab and Date of (51.08 and 63.52 and 56.01%) on the relay to the stage of Khalal, (62.51 and 72.12 and 65.12%) on the relay to the stage of Ritab, (72.51 and 84.47 and 79.81%) on the relay to the stage of Dates, as results showed a decrease in the chemical characteristics (sucrose and the element nitrogen, phosphorus and potassium) for the same treatment of overlap (5 ml Gaton .L - 1 + 40% removal of Spikelet floral) and gave less averages reaching (7.51 and 0.72 and 0.69 and 0.095%) on the relay to the stage of Khalal, (7.00 and 0.54 and 0.51 and 0.072) % on the relay to the stage of Ritab, (4.66 and 0.39 and 0.39 and 0.060%) on the relay to the stage of Date. The results also indicated for the treatment of overlap to spray in Gaton (5 ml \ L) and manual thinning (removing 40% of the Spikelet floral) a decrease in physiological traits (breathing) rate of speed, where the average rate of respiration rate of speed (130.19 mg CO2 . Kgm - 1.saah) The average ratio maturity and moral superiority that showed the rate of (75.80%). The results showed there outweigh the moral to spray Gaton(5 ml . L - 1) and thinning benzyl adenine (200 mg . L - 1) in the qualities of productivity (average bunch weight of Yield the total for Palm), also outperformed the treatment of overlap to spray in Gaton (5 ml . L - 1) and thinning benzyl adenine (200 mg . L - 1) the rate of bunch weight and Yield the total gave the highest averages in terms of (13.33 and 66.67 kg) on the relay
