In Egypt, oranges are the most important citrus crops for local consumption or export. It represents approximately 72.2% of the total Egyptian citrus production in 2019/2020. The main cultivated variety of orange is the Washington navel orange and it is more popular because of its delicious taste, nutrition, and its seedless besides being rich in vitamin C. Washington navel orange is susceptible to fruit cracking, and it is a common physiological disorder that takes place during fruit development. This work aims to investigate the negative effect of fruit cracking in reducing the yield and quality of Washington navel orange produced in Egypt by studying major economic indicators and estimating an economical evaluation of using treatment of Washington navel orange during the period time of 2007/2008 until 2019/2020. Results showed that fruit areas and production of Washington navel orange represented about 52.9% and 53.2% of fruit areas and production of orange during the study period. However, the yield was unstable with a significant annual growth rate of about 1.1%. Also, the last mentioned treatment achieved a high price for farmers by about 5.1% and total revenue of about 3.2% during the study period. Nowadays, Egypt has become the largest exporter of oranges in the world within the last year and the achieved earnings reached $661 million in 2019/2020. In addition, results showed that evaluation of using a treatment to reduce the rate of Washington navel orange cracking was economical to be applied.

This paper aims to establish a methodological frame work and its validation as a response to the need of a demand management tool in the face of recurring comparisons of building revitalization or retrofits. As the investment and implementation actions improve and the social economic criteria are delimited by regulatory frameworks, it is extremely necessary to monitor previous performances and further prospects, regarding projects, it is necessary to measure the extent of which efforts have been meeting regulatory requirements and aiming to contribute with sustainable development. In this context, the use of indicators has been a major management tool.

Tomatoes are one of the most popular and widely consumed vegetable crops worldwide. Egypt is characterized by its tomatoes production, whether for domestic use or export. Summer tomato farmers’ income has recently been reduced due to high production costs, particularly in new lands. As a result, the purpose of this research is to evaluate the economic efficiency of the elements used in summer tomato production in the Borg El-Arab area of Egypt as a new land. According to the findings, the summer tomato crop produced a reasonable profit for small-holding farmers in the study area. However, the elements are being used excessively in the production process, particularly seeds and fertilizers, resulting in increased production costs and failure to achieve economic efficiency of the elements used in the study area.
