This study deals with the estimation of the linear production function of the wheat farms in the irrigated area in order to determine the most important factors affecting the production. The variable (cultivated area, compost, pesticides, and salinity) in the land respectively indicated a negative sign. This indicates that the quantity obtained from the wheat crop was inversely proportional to the above-mentioned variables. This means that these resources were used more than needed and that these resources were used in the third stage of production, making their use uneconomical. Preliminary data were obtained from their field sources by relying on a random sample of wheat farmers that included (100) farms for the production season (2015- 2016), In addition, the partial and total production elasticity was estimated at (0.15) for the land. This means that there is a decrease in the amount of return to capacity. The total productivity of the total resources used in cultivated land is 0.61. This indicates that the use of these resources in society or it was an efficient use. Keywords: Production function, irrigated area, Soil Salinity
