| Abstract | ||
| The present study was conducted in three sites of Basrah orchards namely: Abul-Khaseeb, Hartha and Diear, to investigate the effect of soil properties and quality of irrigation water on growth of date palm (c.v. Sair). Results showed that soil properteies had a significant effect on length of Date palm so that highest correlation coefficient was obtained with organic mater, available nitrogen, available phosphorus and available potassium (r = 0.828**) , (r = 0.837**) and (r = 0.850**) respectively. Soil properties had a significant effect on number of leaves, highest correlation coefficient was obtained from organic mater, available nitrogen , available phosphorus and available potassium (r = 0.853**) , (r = 0.95-05**) and (r = 0.839**) respectively. Irrigation water quality had more effect on length of Date Palm than soil, there was a significant correlation between water pH with length of Date palm (r = 0.834**) and number leaves (r = 0.770*) statistical analysis results showed a positive significant correlation between soil available phosphorus with leaf chlorophyl, carbohydrate , phenolic content (r = 0.903**) , (r = 0.804**) and (r = 0.800**) respectively. The results showed a significant correlation between soil available phosphorus and leaf nitrogen, phosphorus and potassium content (r = 0.865**) , (r = 0.810**) and (r = 0.910**) respectively. The study showed that irrigation water quality had apositine significant correlation between water (NH4) content and leaf chlorophyl, carbohydrate and phenolic content (r = 0.912**) , (r = - 0.855**) and (r = - 0.857**) respectively. Statistical analysis results showed a significant correlation between water (NH4) content and leaf nitrogen, phosphorus and potassium content (r = 0.969**) , (r = 0.956**) and (r = 0.939**) respectively statistical analysis results showed that there were significant differences among sites in physical and chmical properties of growth of Date palm, Abul-Khaseeb site had a significant effect on other sites with all growth Date palm properties | ||
