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

Abstract EN

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 production inputs) and when Guava farms implement a complete control program with agricultural pesticides to treat diseases and follow ...

scientific agricultural guidelines by the ministry of agriculture and research centers result in increasing the productivity of Guava Feddan by 18%, estimated at about 2.77 ton/fed., and reducing losses from the Guava crop by 171.6%, estimated at about 1.33 ton/fed.

this leads to an increase in the productivity of Guava Feddan by about 4.1 ton / fed.

the results of the production functions for the Guava farms that implemented and did not fully implement the agricultural pesticide control program in al-Beheira concluded that: the farmer implementing the program must reduce the amount of human labor and nitrogen fertilizer used in the production process, as well as the amount of nitrogen fertilizer on farms that non-implement the program by replacing it with another element, that is, increasing the amount of organic fertilizer until the value of the marginal product of an item is equal to its opportunity cost.

among the results of the production functions also for Guava farms in Beheira governorate that implemented and non- implement the control program, the farmer must expand the use of the pesticide element until the value of the marginal product is equal to the alternative opportunity cost of the element, resulting in an increase in its profitability, noting that the value of the elasticity in relation to the pesticide element used in the production of farms Guavas that have fully implemented the program are greater compared to farm non-implementing the program, meaning there is a degree of response to increased production for farms implementing about non-implementing farms to the control program, while following technical guidelines and instructions from the ministry of agriculture and research centers, which has a role in reducing the amount of losses, as this results in increased production and profitability of the farms.

the results of estimating the optimal combination of two elements organic fertilizer and nitrogen fertilizer for Guava farms that implemented and did not fully implement the agricultural pesticide control program in Beheira governorate showed that Guava farms in Beheira must increase the amount of organic fertilizer and reduce the amount of nitrogen fertilizer used in the production process to achieve economic efficiency and then reach the optimal production level for those farms.

the research recommends the following: 1.

the results showed that the farmers who responded to the full implementation of the agricultural pesticide control program on their farms had a positive impact in increasing the productivity of their Guava Feddan and increasing the net revenue of the crop.

2.

the ministry of agriculture and land reclamation, in turn, must make technical recommendations to fully implement the agricultural pesticide control program on Guava farms through audio-visual media, research centers, and the agricultural extension sector.
