| Abstract | ||
| Egypt's oranges and grapes are among the most important fruit varieties exported and manufactured in Egypt, where the quantities produced by orange and grape plants contribute about 77% of the fruit industries produced in Egypt. The farmer predicts future prices and on the basis of his farming plan. The study aims to perform a function of the orange and grape shears to achieve the appropriate method. The research was based on the methods of meta-analysis and the most important of its various forms is the estimation factor of the simple and multiple slope function in its various forms, the general direction equation, and the logarithm images. The study found that the total area of oranges increased at a growth rate of about 4.1% during the period 2000-2017, and the productive area increased at a growth rate of about 3% during the same period. With the general time trend of the productive area of grapes in Egypt during the period 2000-2017, it is clear that the average productive area of grapes reached 157.28 thousand feddans during the study period, ranging from a minimum of 129.69 thousand feddans in 2000 to a maximum of 198.91 thousand feddans in 2002. Egypt's average grape crop production is about 1.44 million tons, ranging from a minimum of about 1.08 million tons in 2000 to a maximum of 1.81 million tons in 2002. The response to the Orange offer showed that by increasing the area grown in the previous year, the area grown the following year by 522,000 feddans, and by increasing the price of oranges the previous year, the area grown the following year by 94 GnF/ton. The study found the expansion of the cultivated areas of fruit, improved production methods and increased manufacturing capabilities that would benefit the national economy. | ||
