دراسة اقتصادية لاقتصاديات إنتاج الخضر بالصوب الزراعية

الملخص EN

The research aimed to study the economics of producing cucumber and pepper crops in greenhouses in Sharkia governorate by identifying the determinants of the production capacity and economic efficiency of greenhouses and statistically estimating the production cost functions of the vegetable crops under study, which are cucumber and pepper under protected cultivation conditions, with determining the optimal size of production from the farm resources used.

and the combination of production elements that maximize economic efficiency, net return per square meter, and the profitability of the invested pound, that is, the return on capital, to put it in the hands of producers or investors to take into account when making their decisions and drawing up their production policy.

for the first category, it is represented in the amount used of human labor, the number of seedlings, the amount of effective units of phosphate fertilizer used in kilograms, and the amount of irrigation water, and that 92% of the changes in the productivity of each 150 m 2 of cucumber in the study sample are due to the previous elements, with regard to the efficiency of the production elements, and the results indicated the value of the marginal product of human labor, mechanical work, phosphate fertilizer, and the amount of irrigation water used exceeds the cost of obtaining a unit of it, and this indicates that the quantity used is less than the quantity that achieves efficiency, and that increasing the use of these elements leads to an increase in production.

as for the pepper crop, it was found from the estimated model, the most important elements that have a significant impact on the production of each 150 m 2 crop of pepper grown in greenhouses at the level of the total study sample are represented in the amount used of human labor, the number of seedlings, and the quantity of effective units of ammonium sulfate fertilizer, superphosphate fertilizer, and potassium sulfate fertilizer used in kilograms (unit).

effective) and the amount of irrigation water, and that 97% of the changes in the productivity of each 150 square meter of pepper in the study sample are due to the previous elements.
