EFFECT OF NITROGEN , IRON AND THE METHODOF APPLICATIONON SOME NUTRIENTS ABSORPTION FOR APPLE LEAVES

Abstract

The research was Carried out in the apple orchard C.VAnna which was established in the Botanical Garden – College of Agriculture – Baghdad University Campus at Al-Jadriyah during the growing season of 2015,Afactorial experiment was carried out by two factors according to the Randomized Complete Block Design (RCBD) the first factor included Nitrogen applied in three ways (without addition ,foliar application at 4 g N l-1 and ground addition at 50 g N tree-1) and the second factor includedapplyingChelated Iron Fe-EDDHA in three ways (without addition, foliar application at 20 mg l-1and ground addition at 20 g tree-1)the aim of this research was to study the effects of Nitrogen and Iron on the absorption of nutrients inapples seedlings. The Treatments were replicated three times with two seedlings per experimental unit.The results showed a significant increase in the concentration of Nitrogen, Phosphorus, Potassium,total and active iron in the leaves with nitrogen and Chelated Iron treatments individually and with both methods of application,NSFeS( Nitrogen and Iron ground treatment )also gave a significant effect in increasing all parameters except for phosphorus content, the Nitrogen and Iron ground added treatments also surpassed the foliar applicated treatments as well as the control in all the traits except for Phosphorus content.
