The Response of Date Palm Phoenix dactylifera L. cv. 'Barhii' to Spray by Two Vital Stimulators Terrasorbe and Kelpak

Abstract

This study was conducted in one of the private orchards at Al-Hwair district at Al-Qurna north Basrah in 2013. The study aimed to determining the effect of spray by the two vital stimulators: terrasorbe and kelpak on some physical, chemical ,and productive characteristics of date palm cv Barhii. The results showed an increase of spray treatments by 6ml/L terrasorbe in the physical characteristics under study (fruit length, diameter, Wight, and size) in which the highest values were scrod (3.60cm 2.64 cm, 10.57 g ,12.65 cm ) respectively. spray treatment by 6m/L terrasorbe showed the highest percentage of total soluble solid materials (59.75). whereas the spray treatment by 6ml/L kelpak showed the highest percentages of total sugar and reduced (sugar as well as sucrose which were (46.45, 18.11, 28.34 ) respectively. The two treatments of this study showed an increase in the productive features (maturation percentage, bunch weight ,and total productivity of the date palm). The highest values were scored during spray treatment by 6ml/L kelpak which were (68.3555% ,17.88 kg ,and14.11 kg ) respectively. The interaction of the two treatments showed significant difference in the characteristics under study.
