The research aimed to assess the indicators of the feasibility of investment in mango farms in Sharkia Governorate, Egypt and to assess the impact of potential changes in the most important technical and economic variables on the feasibility of investment in the activity of mango production, and to identify the most important problems facing mango farmers.

The number of its vocabulary is 20 farms for mango activity in the Salihiya area, which occupies the area of mango gardens with relative importance the first rate was estimated at 40.07% of the total mango area in Sharkia Governorate, which amounted to about 33.93 thousand faddan. Magnificence in Salhiya region, which amounts to about 13.6 thousand faddan. The technical and economic performance of these farms was analyzed using the farm income statement and the investment analysis list.

The study recommends the expansion of mango gardens projects, especially the cultivation of Kate variety in the new lands due to the high values of the various indicators of return on investment. It also recommends overcoming the agricultural problems facing mango farmers to improve the production of mango gardens in the study area.
