| Abstract | ||
| The present study was carried out in 2012 at a sand texture at Al –Najaf station and a loam texture at Al-Kadher station-Horticulture Office - Ministry of agriculture. The study included the influence of soil texture with three levels of water irrigation salinity on same soil nutrients content (N, P, K, Ca, Mg, Na, Ec, PH) and some nutrients uptake (N, P, K, Ca, Mg, Na) by date palm seedlings (Phoenix dactylifera L, leaves number and yield ( in fifth year) for Kestawi cultivar. The result showed: 1- There was significant increase in electrical conductivity values with increasing of irrigation water salinity in both textures and found out significant differences in electrical conductivity values in loam texture. 2- There were significant differences among treatments in available nitrogen content with increasing of irrigation water salinity in both textures and a significant decrease in a panna's nitrogen phosphorus and potassium contents with increase of water irrigation salinity. 3- There were significant increases in available calcium, magnesium and sodium content in soil with increasing of irrigation water salinity in both textures and a significant decrease in a panna's contents with increasing of water irrigation salinity, but in paradox all nutrients a panna's sodium contain increasing with increasing of water irrigation salinity. 4- There were a significant decrease in yield and leaves numbers with increase of irrigation water salinity. | ||
