This research aimed to study the productivity and economic indicators of the summer potato crop in Egypt and then estimate a supply response model to understand the decisions made by the producers of this crop. These decisions help determine whether they expand this production activity, reduce it, or abandon it altogether. Additionally, the study addresses how the available resources are directed by these producers towards expanding the production of other suitable vegetable crops. Furthermore, the research estimates marketing efficiency indicators and examines the geographical distribution of the main importing countries. It also statistically estimates the external demand functions for Egyptian potato exports in key global markets. The research findings revealed that the governorates of Lower Egypt ranked first in terms of the area cultivated with summer potatoes, accounting for about 100.297 thousand feddans, representing approximately 72.53% of the total area cultivated with summer potatoes in Egypt, which amounts to around 138.278 thousand feddans during the average period (2018-2022). The results also showed that the most significant explanatory variables affecting the dependent variable, which is the area cultivated with summer potatoes in the current year (Y), are (X1) the area cultivated with summer potatoes in the previous year, and (X4) the farm price of summer potatoes in the previous year. These two variables were statistically significant at the 0.01 level, and their signs were consistent with economic logic. The supply response elasticity for these variables was estimated at about 0.52 and 0.33, respectively.
