Abstract EN

The research problem is the relative stability of grape productivity despite the high production costs.

The research aimed to identify the efficiency of the use of agricultural resources used in its production to identify the economic effects of that problem at the level of the most important varieties cultivated from it in the new lands in Beheira Governorate.

It is clear from the results of the study that the new lands in Egypt contribute about 68.7% of the grape production in Egypt, and the old lands contribute about 31.3% .

It was also found that the production of girl grapes represents about 2.4% of the total production of grapes in Egypt, followed by the turkey grapes with a relative importance of about 24.1% and the Flame Seedless by about 16.5% , and the Early Asprior by about 1.6% and the Crimson by about 1.2% and each of Fayoumi and Al-Baladi by about 0.9% , followed by that with a contribution The rest of the other items by a small percentage.

It is clear from the economic indicators of the study sample, which included three grape varieties: Banati, Crimson, Flame Seedless, that the net return per feddan amounted to 29, 411 pounds for Crimson, 24763 for Flame Seedless, and 13307 for Banati.

The profitability of the pound for each of them was about 51.5% , 45.6% , and 30.2% , respectively.

The estimation of the grape production function of Flame Seedless cultivar showed a positive and statistically significant effect of each of the organic, phosphate, nitrogen and potassium fertilizers on its feddan productivity
The total elasticity of the function, estimated at about 1.47, indicates the existence of the phenomenon of increasing the return to capacity, that is, the production of grapes of the Flame Seedless variety in the study sample in the initial stage of production, which is not economical.

The estimation of the Crimson grape production function showed a statistically significant positive effect for the same previously mentioned variables, and a statistically significant positive effect for each of the leaf nutrients and human work on its feddan productivity.

The overall elasticity of the function (2.3) indicates an increase in the yield to capacity, which means that the production of Crimson grapes in the study sample is in the first stage of production, which is the non-economic stage.

It was found from the estimation of the function of the production of girl grapes that there is a positive effect of the same variables mentioned above on its feddan productivity, and the total elasticity of the function (1.53) indicates an increase in the return to capacity, meaning that the production of girl grapes in the study sample is in the first stage of production, which is the non-economic stage.

Which indicates the need to intensify the use of production elements in the three aforementioned grape varieties to move to the economic stage of production, which is the second stage.
