دراسة محاكاة النموذج الرياضي للاحتياجات 8 Cropwat المائية للذرة الصفراء [.Zea mays L] وفق مستويات و طرق ري مختلفة في شمال سوريا

Abstract EN

The irrigation water management in an era of water scarcity must be applied more efficiently and effectively in order to save water and get to a higher production of the crop.

Cropwat 8: mathematical model developed and produced by the Food and Agriculture Organization (FAO).

It aims to help decision-makers in development of water plans by computing the crop requirement water and irrigation needs.

In 2014 was the introduction of the data to the model mentioned above and for six seasons maize under selected irrigation treatments irrigation methods (developed surface, spray, drip), and.

The implementation of four agricultural seasons in Srbaya Research Station (2004-2007), and two seasons in Tel Hadya Research Station (2007 and 2008), followed to Aleppo Research Center.

In order to test the extent of this simulation program for the results obtained from the field experiments.

The results showed between Cropwat 8 simulation program and the reality field results for 100% and 85% irrigation treatments that the model has a weak sensitivity.

Also it showed there was no shortage of production of grain yields in spite of its presence in the reality of the experience.

The deficit irrigation treatments, cropwat 8 improved the performance, and improved performance in its response to the shortage of grain yield.

The resultsshowed that programmay be more insensitivefor full irrigation onmaize,and may be improveits performancewell withlow wateraddedquantity.There are many studies to agreement this results,It is possiblethat this programhelpsconcernedto augurynecessaryplansfor futurewaterrequirements.
