تقييم الملاءمة المكانية بين خصائص المناخ و زراعة محصول الذرة الصفراء في محافظات الفرات الأوسط باستخدام (GIS)‎

Abstract EN

The research deals with the climate characteristics affecting the cultivation of the yellow corn crop in terms of determining the best lands for cultivation based on those characteristics.

In addition to plant production, specialists began searching for the best means and methods to reach the optimal areas for crop cultivation, and among these methods is the technology of geographic information systems (GIS).

Geographical lands are defined and classified according to the suitability of their climate.

In light of this, the climatic characteristics were evaluated and classified as (solar radiation, temperature and relative humidity).

The evaluation and classification process was carried out in the Geographic Information Systems (GIS) program, by reclassifying it with the Reclassify tool, according to the requirements of The yellow corn crop from them based on the (SYS) standards approved by the Food and Agriculture Organization (FAO), which set ideal limits for corn It was represented by five levels (N2-N1-S3-S2-S1), in addition to making a model for the final spatial fit by applying (Model Builder) and then using the (Overly Weighted) tool to give a weight for each of those properties depending on its importance and its impact on the crop.

and its amount in the soil, and accordingly the research concluded that there are four levels of suitability which are (N2-S3-S2-S1), as the two categories (S2-S1) of high suitability and medium suitability recorded the highest percentages as they reached (79.6%) of the percentage of the area of the study area.
