Spatial Analysis Of The Production Of Main Grain Crops In Al Muthanna Governorate For The Year 2019

Abstract

The research aims to clarify the variation of the areas of cultivation of grain crops in Al-Muthanna Governorate, as the area of the barley crop reached (3500 dunums) in the Rumaitha district, followed by the Warka district with an area of (1320 dunums), while no area of the rest of the administrative units was recorded, such as Al-Samawah district center, Al-Suwayer district, Al-Khader district, and the district Al-Darraji and Salman district. As for the wheat crop, the Salman district recorded the highest cultivation area for the crop, reaching (112004 dunams), followed by the Najmi district with an area of (14,000 dunams). As for the lowest administrative unit, it was in the Suwayer district (1116 dunams), and with regard to the rice crop, it reached The highest area in the Rumaitha district is (3500 dunams), followed by the Warka district center (1320 dunums), while there are administrative units that did not grow the rice crop due to the lack of natural and human factors necessary for them, such as the district of Samawah, Al Khader, Salman and others, and that the variation in crops is restricted. The study is mainly due to natural and human factors, as it affects the distribution of areas, production and productivity, and the most important of these factors are location, as it affects the angles and the amount of solar radiation, degrees of temperature, humidity, winds as well as the type of surface H, which is considered one of the most important requirements for the cultivation of cereal crops, in addition to the effect of the size of the vegetation cover and the amount of water resources (shabeh is scarce) in the study area. All of these factors affect the type of soil, its texture and the amount of nutrients (humus) present in it.
