Potatoes are among the most important Egyptian vegetable crops in addition to their export importance, as they represent an advanced position among vegetable crops in terms of the cultivated area and the quantity of production.

Old and new lands The main objective of the study was determined to measure the economic impact of brown rot disease on the production of the summer potato crop with the study sample, where the sample was chosen in a phased random manner (multi purpose).

The summer potato crop in the villages of Wadi Al-Natrun area in Nubaria during the agricultural season 2019/2020, which is 60 observations, and it includes two categories of farmers (not implementing the brown rot program, and applying the brown rot program).

The brown mold program was higher than the farms applied in both: the amount of ammonia nitrate used (effective unit), the amount of potassium fertilizers (effective unit), and the amount of agricultural sulfur used (kg/feddan), while the farms applying the brown rot program were higher in each From: the amount of human work (man / feddan), the amount of automated work (hours / feddan), the amount of seeds (tons / feddan), the amount of municipal fertilizer (m3 / feddan), the amount of superphosphate used (effective unit) and the amount of feddan productivity in tons, as The results of the study showed that the total revenue per acre (pounds / acre) was about 80038 (pounds / acre) in the farms that did not implement the brown rot program, and about 84,751.33 (pounds / acre) in the farms applied for the brown rot program, and it was also found that the net yield per acre (pounds / acre) was about 26604.61 (pounds / acre) in the farms that did not implement the brown rot program, and about 29,259.8 (pounds / acre) in the farms that applied for the brown rot program, and in light of the results that were reached, the study recommends The need to rely on early production technology, tighten control over imported seeds to ensure that they are free from diseases, especially brown rot and insect infestations, and activate the role of agricultural extension, and work to encourage potato growers to increase the areas that apply the anti-brown rot program by increasing the farm price of the crop and announcing it In advance, the need for a strategic planning for the production of the potato crop for export.
