The research derives its importance from the importance of potato crop, which is one of the four most important crops in the world besides rice, wheat and corn, Despite the expansion of the cultivation of potato crop in Iraq in general and Ameriyah district in particular However, potato production remains substandard, This may be due to the lack of knowledge of the appropriate varieties of environmental conditions that contribute to raising the level of productivity, Therefore, the research aimed to estimate the functions of potato crop production considering the cultivated seed variety as one of the factors affecting potato production and to know the effect of cultivated variety on the production function and determining which potato seed is of high productivity and good economic returns.

The research was conducted on a sample of 183 randomly distributed farms in the study area of the spring loop 2018.

Phantom variables were introduced to examine the effect of cultivar on potato production function potato production functions were estimated type Cobb-Douglas using EViews 9 and SPSS It was found that the Safrana variety was the best variety with a positive effect on the technological factor followed by the Arizona variety, while the Sanjari variety had a negative effect, The production elasticities of urea fertilizer, dab, manual labor, mechanical work and seed quantity were (0.197, 0.144, 0.295, 0.106, 0.185), respectively, which indicates that manual labor is more flexible which means the dominance of handicrafts in the service of the crop, The total production elasticity of 0.927 indicates that the producers are working in the second phase because the total production elasticity is positive and less than one integer it indicates that the increase in all elements of production by 10% followed by an increase in production of 9.27% .

So it is recommended to plant the Safrana variety, And work on the use of productive elements as recommended by the concerned authorities.
