التحليل المكاني للمكننة الزراعية و علاقتها المكانية بزراعة محاصيل الحبوب في محافظة ميسان

Abstract EN

Agricultural mechanization is the backbone of various agricultural operations for its great role in increasing production and reducing costs, effort and time.

The research aims to study the spatial analysis of agricultural mechanization (pumps, harvesters, pullers and sprinkler irrigation systems) and their spatial relationship to the cultivation of grain crops (wheat, barley and rice) at the level of districts in Maysan Governorate for the year 2022.

The spatial variation of the types of agricultural mechanization and the area of grain crops in the study area were shown through Representing them on maps using the 10.4 Arc GIS program after categorizing them into several categories using the (logarithmic transformation) method.

And finding the spatial relationships between the types of mechanization and the area of grain crops using the statistical bag SPSS through the application of the technique of correlation and regression.

And measuring the adequacy of this mechanization according to the areas planted with grain crops in the study area using mathematical equations.

The Lawrence curve was also used to measure the degree of concentration in the spatial distributions of mechanization numbers relative to the area of grain crops.

The research reached several conclusions, the most prominent of which is that there is a strong positive correlation between the variables of wheat and barley area with the independent variables, which amounted to 0.91 and 0.81.

As for rice yield, it had a strong positive relationship with the pumps variable, which amounted to 0.83 for its need for water, and an inverse relationship with the rest of the variables with a multiple correlation coefficient of 0.95.

The Lawrence curve also showed that the non-ideal distribution of mechanization for wheat and barley crops in the districts of Al-Salam, Al-Musharrah, Sayed Ahmed Al-Rifai, and Al-Mamouna is close to the ideal in the rest of the districts.

While it was ideal for rice in Al-Musharrah and Al-Adl, and close to ideal in the rest of the districts.

The research found insufficient mechanization of the areas planted with grains, as the governorate needs 478 harvesters and 6054 pullers to suffice the areas planted with grains.
