The effect of climate and water resources on growing wheat and barley crops in the Najaf governorate

Abstract

Wheat is considered one of the basic foodstuffs, as it is the main material in the manufacture of loaves of bread and pastries. It comes second to humans after rice in its nutritional importance in several places of the world (including Iraq and including the study area), and its nutritional value is derived from its containment of starchy and nitrogenous material. The same applies to barley, which is one of the most important crops in the world, as it is ranked third in the world in terms of economic importance after rice and corn. The research came with five topics, the first was a theoretical framework, the second dealt with the natural characteristics of the study area, and the third discussed the effect of climate on the cultivation of wheat and barley crops, while the fourth topic dealt with the effect of water resources on growing wheat and barley crops, and the fifth topic came to shed light on the distribution Geography of wheat and barley crops in the province of Najaf. The research concluded a set of conclusions, including the effect of wheat and barley crops on the natural factors represented by the surface and climate elements, as we note the impact of these factors on the productivity of crops. We notice in the fourth topic the fluctuation of incoming water to the study area, which in turn led to fluctuation of production in some cultivated areas. It appears from the study of the geographical distribution of wheat crop in the study area that the Qadisiyah district occupied the first rank in wheat production for the year of study, while the freedom region ranked last for the production of this crop. From the study of the geographical distribution of the barley crop in the study area, it is clear that the Najaf District Center occupied the first rank for barley production, while Al-Huriya and Al-Abbasia districts occupied the last centers for barley production.
