تأثير خصائص الترب و نوعية مياه الري في نمو فسائل نخيل التمر Phoenix dactylifera L. صنف الخضراوي

الملخص EN

This study was conducted in three sites of Basrah fields.

The first site at in Abul-Khaseeb, other sites at Hartha and Diear, to investigate the factors including soil properties and quality of irrigation water on growth of date palm (c.v.

kdrawi).

The results showed that Soil properties had a significant effect on number of leaves, highest correlation coefficient was obtained with organic mater, available nitrogen , available phosphorus and available potassium (r = 0.866**) , (r = 0.866**) , (r = 0.853**) and (r = 0.843**) respectively.

Irrigation water quality had a significant correlation between water pH with number of leaves (r = 0.780*) statistical analysis results showed a positive significant correlation between soil available phosphorus with leaf chlorophel, carbohydrate , phenolic content (r = 0.918**) , (r = 0.823**) and (r = 0.810**) respectively.

The results showed that was a significant correlation between soil available phosphorus with leaf nitrogen, phosphorus and potassium content (r = 0.869**) , (r = 0.843**) and (r = 0.886**) respectively.

The study showed that irrigation water quality had appositive significant correlation between water (NH4) content with leaf chlorophel, carbohydrate and phenolic content (r = 0.923**) , (r = - 0.880**) and (r = - 0.869**) respectively.

Statistical analysis results showed a significant correlation between water (NH4) content with leaf nitrogen, phosphorus and potassium content (r = 0.953**) , (r = 0.960**) and (r = 0.943**) respectively statistical analysis results showed that there were significant differences among sites in physical and chmical properties of growth Date palm, Abul-Khaseeb site had a significant effect on other sites with all growth Date palm properties.
