| Abstract | ||
| The present study was carried out at a sand texture Al –Najaf station / General board of date palm / ministry of agriculture to study the influence of water irrigation salinity on soil nutrients content, chemical properties N,P,K,Ca,Mg,Na,Ec,PH and some nutrients N,P,K,Ca,Mg and Na uptake by Date Palm seedling (Phoenix dactylifera L ((in fifth year) for Kestawi and Mactoom cultivars, the result showed: 1-There was an increase in electrical conductivity values with increasing of irrigation water salinity. The higher value of electrical conductivity recorded at third level of water irrigation salinity also found a significant effect of Mactoom cultivar in decrease of soil electrical conductivity values than Kestawi cultivar. 2-Available nitrogen decreased with soil deep and water irrigation salinity increasing, the change in cultivar did not record any differences in soil available nitrogen, a significant decrease in a panna's nitrogen content with increase of water irrigation salinity. Panna's phosphor and potassium content decreased with increaseing water irrigation salinity. 3-Calcium and magnesium decrease with soil depth and panna's calcium and magnesium content decrease with water irrigation salinity. Soil sodium recorded a significant increasing in content at the second layer in sand texture. There were significant differences in a panna's sodium content, but in paradox all nutrients a panna's sodium content increased with increasing of water irrigation salinity. 4-Kestawi recorded the higher yield and number of leaves than Mactoom cultivar. Also the study found a significant decreasing in yield with increase of irrigation water salinity. | ||
