The study found that there is a decrease in productivity, and the results of the comparative analysis between the average per-acre productivity of the most important varieties of the Levantine maize crop in the governorate showed that the hybrid variety Hitech 2031 occupies first place with an average per-acre productivity estimated at about 21.61 ardab.  It turned out that the single hybrid variety Hitech 2031 achieved the highest transmission coefficient, and this variety with the highest productivity and transmission coefficient for the yield function of Levantine maize can be grown in the governorate in place of the areas in which the varieties with the lowest transmission coefficient are grown, with a shift of the supply function to the right.
 
 The research relied on primary data through two independent samples of maize farmers in Sohag Governorate for the 2022 season, each of which numbered 105 farmers. The first sample represented farmers of the local variety and the second the farmers of modern hybrid varieties. It was found that the first sample followed the level of application of the average, while the second followed the level of High for implementing integrated control provisions.  It turned out that the profitability of the unit produced from the crop in the two research samples was estimated at about 213.1 and 698.3 pounds per ardeb, and thus the advantage of the second sample, representing farmers of hybrid varieties, over the first in terms of productivity and revenue of the unit produced.
