Abstract EN

Sugar is a strategic food commodity of great interest at the global and domestic levels, and the sugar industry is an important manufacturing industry that relies on sugar as a strategic food commodity that is of great interest at the global and local levels and the sugar industry in Egypt depends on two main crops, sugar cane and sugar beet, and statistics indicate a significant development in the extent to which the sugar beet crop contributes to the total production of sugar in Egypt, where its contribution was 67.7%, the share of sugar cane yield slumped gradually to about 32.3% in 2021, while domestic sugar consumption in Egypt reached about 3.320 million tons of sugar, resulting in a sugar gap estimated at about 0.608 million tons of sugar in 2021.

by studying the results of the supply response model for the sugar beet crop in relation to the variables of the competing crops, it was found with respect to the variable of the cultivated area in the double logarithmic form, it was clear that there was a statistically significant inverse relationship between the area cultivated with the sugar beet crop per thousand feddans in the current year as a dependent variable and each of the area planted with permanent alfalfa in the previous year, the area planted with fava beans in the previous year, and the area planted with winter onions in the previous year, which is consistent with the economic logic ; as for the price of the crop, despite the significance of the model, there is a direct relationship between the area planted with sugar beet in the current year and the planting price of the sustainable alfalfa crop in the previous year, and this does not agree with the economic logic, and with regard to the production costs variable, it was found that there is a direct relationship between the area planted with beet crop sugar in the current year and each of the total costs of producing an acre of sustainable alfalfa crop in pounds in the previous year and the total costs of producing an acre of faba bean crop in pounds in the previous year, which are consistent with the economic logic, and the morality of the model has been proven.

the former is inconsistent with economic logic.
