Citrus is one of the most important fruit crops grown in Egypt, as it occupies the first rank of the fruitful area, the problem the related to citrus and tangerine crop (Calmentina) specian, which is crop of the study where it has many problems such as high production costs and low net returns, and the research aims to study the current production situation of tangerine crop in Egypt and North Sinai Governorate, study relied in achieving its objectives on secondary and primary data, results showed that average total area amounted to 107.3 thousand feddan, while the average fruitful area amounted to 96.4 thousand feddan, and average feddan productivity amounted to about 8.3 tons/ acre. Average total production amounted to 785 thousand ton, while the number of sample farms reached 140 farms, and the average share of holder was about 1.20 feddan. Average number of trees per acre has reached 208 trees. Average productivity of the tree was 57.3 kg/ year, while the average productivity of an acre was 8.28 ton/ year, and the relative impact of the production elements was studied, which are chemical fertilizers, organic fertilizers, fungicides and insecticides, human labor and number of automated working hours. Economic analysis of production and cost functions for tangerine crop was also estimated. Study recommends increasing the number of trees per feddan and applying chemical and organic fertilization programs while providing hired human labor.
