Abstract
This experiment has been carried out in the nursery of college of Agriculture and Forestry, Mosul University, Iraq during the season of 2005 to study the effect of five agricultural media : sand loam soil (river soil) 100 % ;sand loam soil : manure (3:1) by volume ; sand loam soil : peat moss (3:1) ;sand loam soil : manure : peat moss (3: 1/2 : 1/2) and sand loam soil : manure : peat moss (2: 1 : 1). Seedlings has been sprayed with three levels of GA3 (0, 50, and 100 mg.l-1) as well as three level of chelated zinc Zn-EDTA (0, 25, and 50 mg.l-1)and their interaction . The aim of the present study was to know the best agriculture media and concentration of GA3 and Zn-EDTA for improving the growth of pistachio rootstocks during one seasons. The results obtained in this study could be summarized as follows : Using the Fourth mixture gave the best results of stem diameter, leave number per seedlings and total chlorophyll. Fifth media gave the highest stem height. Spraying plants with 100 mg GA3.l-1 caused significant increase in plant height, stem diameter and number of branches. Foliar application with 50 mg Zn.l-1 resulted in a significant effects on plant height, leaves number, root length and total chlorophyll content. However, the interaction between Fifth and Fourth media which sprayed with 100 mg.l-1 GA3 + 50 mg Zn.l-1 improved all vegetative growth parameters and root length.
