Abstract

The experiment was carried out in a private orchard at Shat-Al- Arab District, Basrah Province during the summer seasons of 2011and 2012 in order to study the effect of irrigation water quality and spraying with Tocopherol on growth and yield of okra plants tolerance to salinity resulted from irrigation by salinity water and its effect on the leaves of chemical parameters. Treatments included three sources of water (i.e. tap water, tap water + river water 1:1 and river water) and spraying plants with Tocopherol at four concentrations 0, 50, 100 and150mg. l-1). Treatments of this experiment were distributed in Split Plot Design with three replicates, which were the main Plots represented water sources, spraying with tocopherol represented sub-plots. Means were compared according to L.S.D. Test at significant level of 0.05. Result could be summarized as follows: Plants irrigated with tap water had a significantly higher parameters (N, K, K+/Na+ ratio), carbohydrate, leaves chlorophyll concentration, abscisic acid contents in leaves for both seasons,.Foliar application with Tocopherol at 150 mg.l-1 caused an increase in N,K, K+/Na+, total soluble carbohydrate and chlorophyll contents in leaves while resulted decrease in proline and abscisic acid contents in leaves.The interactions between the studied factors were significant in all studied parameters for both seasons.
