الأثر الاقتصادي للفاقد في محصول الجوافة على الإنتاجية الفدانية في محافظة البحيرة

By studying the economic impact of losses in the Guava crop on the productivity of Feddan in Beheira governorate, the reasons for the losses in the crop are attributed to not determining the optimal stage for fruit ripening, high soil salinity, and the infection of trees with fungal and viral diseases, nematodes, and insects. therefore, failure to fully implement the program to control agricultural pesticides leads to a waste of the resources used and a high percentage of losses in the Guava crop, which results in losses to farmers, including a decrease in their profitability, and consequently a decrease of agricultural production, and amount of agricultural exports of the crop. the results of the research showed an increase in the Feddan productivity of the Guava farms that fully implemented the pesticide control program in Beheira governorate, about 3 ton/fed., representing about 20% of the Feddan productivity of the non-implemented farms. this is due to determining the optimal maturity stage for the fruits, treating soil salinity, and combating the infection of Guava trees with fungal diseases, viruses, nematodes, and insect pests, this leads to no waste of the resources used and no loss of the crop, which resulted in an increase in the per Feddan revenue for the farms implementing the program by about 20.3% over the non-implementing farms. this was reflected in an increase in the net per Feddan revenue from Guava in Beheira for the implementing farms by 89% compared to the non-implementing farms. this is due to an increase in productivity and revenue and a decrease in crop loss by 187%, and decrease the total and variable costs of the implemented farms increased by (1.9%, 3.3%) compared to the non-implemented farms, and the increase in per Feddan productivity and return for the Guava farms that implemented the entire agricultural pesticide control program increased by (20%, 20.3%), respectively, resulting in an increase in (relative profitability, return on the invested pound, and the percentage profit margin and profitability per ton) by (52%, 93.8%, 14.1%, 57.4%), respectively, unlike its counterpart, which did not implement the full control program for Guava farms in Beheira. by analyzing the productive problems of the Guava crop in Beheira governorate, represented by (infection with diseases, high soil salinity, failure to determine the optimal ripening stage for fruits, weak role of agricultural extension, low selling price, high prices of product
