تقيم كفاءة الخف اليدوي و الكيميائي و الرش بمستخلص الأعشاب البحرية (الجاتون)‎ في الصفات الفيزيائية و الإنتاجية لنخيل التمر Phoenix dactylifera L. صنف الحلاوي

Abstract EN

This study was conducted in one of the orchards civil in Albradaah area in the province of Basra to the growing season 2014 on the date palm Phoenix dactylifera L.

class Hillawi in order to study the effect of spraying fertilizer Gaton (seaweed extract) and concentrations (0, 2.5 0.5 ml) \ L after inoculation and hold process sock both types manual Hmarich flowering (25% and 40%) of the number Achammarek flowering after inoculation and chemical thinning Abannzel adenine (growth regulator) and concentrations (100 and 200) mg \ l in addition to treatment comparison (no thinning), was carried out spraying the total vegetative and fruiting date palm of Gaton and Abannzel 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 on the physical and productivity of the date palm class Hillawi, which was Gaton factor with three levels and thinning five levels.

Use the full random sectors 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 as follows: - Results showed superiority of treatment overlap to spray in Gaton (5 ml \ L) and thinning Abannzel denine (200 mg \ l) 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 Khallaal, and rtib and dates on the relay and the weight of the seed where was (1.380 and 1.290 and 1.280) g of the stages of sorts and rtib and dates on the relay and the weight of stromal layer where was (6.170 and 5.760 and 5.170) g of the stages of Khallaal, and rtib and dates on the relay and also outperformed significantly in size and the length and diameter of the fruit and gave the highest averages in terms was (7.60 cm and 3.83 cm and 2.11 cm 3) on the relay to the stage Khallaal, (7.10 cm 3 and 3.86 cm and 2.00 cm) on the relay to the stage of rtib, (6.56 cm 3 and 3.89 cm and 1.96 cm) on the relay to the stage of dates compared to transactions other under study .

The results showed there outweigh the moral to spray in Gaton (5 ml \ L) and thinning banzel adenine (200 mg \ l) in the qualities of productivity (total winning amount for Palm), also outperformed the treatment of overlap to spray in Gaton (5 ml \ L) and thinning banzel adenine (200 mg \ L) total winning amount as gave the highest average of (66.67 kg).
