An experiment was conducted during season of 2015 at AL-der, north of Basrah.

The aim was to study the Effect of salt stress on leaf mineral element content for three offshoot for date palm The study inluded nine treatment in factorial combinations of interaction with three offshoot for date palm cultivar(sayer,Hillawi and khudraw ) and three concetrtion of NaCl (0,7,15) .Randomized complete Block Design was used three replicates .

test was at probability of 5% .

Result showed that increasing NaCl concentration In the irrigation water caused a decrease in nitrogen ,phosphorus ,potassium,Calcium and mainganes in leaves for both cultirats( Sayer ,Hillawi and Khudrawi) .wharase it cause an increase in proline cotent.

The cuctivar sayer had asignificantly hight in the in nitrogen ,phosphorus ,potassium,Calcium , minganes and proline in content of date palm in leaves The interation between the two factors caused significant effect in all studided parameters.
