Abstract EN

This study was conducted in the field of Horticulture and Landscape Design Department / College of Agriculture /University of Kirkuk, during the period from August 18, 2013 to june 1, 2014 on the olive seedling (Olea europaea L.) of bashiqa cultivar with the objective to study the effect of the salinity of irrigation water (control , 4000 and 5000) mg.

l-1., foliar spray with potassium at concen- trations (0 and 1000) mg.l-1 and foliar spray with Gibberellic acid at concentrations (0 and 100) mg.l-1 and their interaction in characteristics chemical of leaves (percentage of total carbohydrates , leaves contain of praline , percentage of nitrogen , phosphorus and potassium).

led increasing levels salinity of irrigation water to decreased significantly percentage of total carbohydrates , nitrogen , phosphorus and potassium, but it leaves contain of proline was increased signi- ficantly with increasing levels of irrigation water salinity.

while Foliar spray with gibberellic acid at concentration (100) mg.l-1 caused not significant The percentage of the total carbohydrates , nitrogen , phosphorus and potassium, but it caused significant effect in leaves contain of proline, Whereas spraying with potassium led to significant increase in percentage of total carbohydrates , nitrogen , phos- phorus and potassium, and to significant decrease in the leaves content of praline.
