PRODUCTIVITY OF WHEAT AS AFFECTED BY IRRIGATION SYSTEMS, NITROGEN LEVELS AND FOLIAR APPLICATION UNDER NEWLY RECLAIMED SANDY SOILS

Two field experiments were conducted at the Experimental Station Farm in Kalabsho and Zayian Region, Faculty of Agriculture, Mansoura University during the two successive winter seasons of 2004/2005 and 2006/2007 to determine the effect of two irrigation systems (flooding and sprinkling), four nitrogen levels (60, 80, 100 and 120 kg N/fed) and foliar application with some commercial compounds (Nervatin-vet and Maxifert) as well as their interactions on growth, yield and its components and quality of wheat (Triticum aestivum, L.) Sakha 93 cultivar.
The main results of this study can be summarized as follows:

Irrigation of wheat plants through sprinkling method significantly increased all studied characters as compared with flooding irrigation in both seasons.  
Concerning the effect of nitrogen fertilizer levels the all studied characters were remarkably increased as a result of increasing nitrogen levels from 60 up to 120 kg N/fed in both seasons.
Application of foliar compound containing macro and micro elements (Nervatin-vet) resulted in a significant increased in grain yield and straw yields and its components as compared with the compound containing microelements alone (Maxifert) and control treatment in both seasons. Maxifert exceeded control treatment in all studied characters.

It can be concluded that in order to maximizing wheat crop productivity it must be irrigated through sprinkling irrigation system and mineral fertilized with 120 kg N/fad as well as foliar fertilized with  some commercial nutrient compounds that contain macro and micro elements such as Nervatin-vet under the environmental conditions of Kalabsho and Zayian district as a newly reclaimed sandy soils.
