Among all other agricultural products, cotton has an important place in terms of added value contribution, and wide usage variety in different industries. Turkey is 8th biggest cotton producer in the World. Hatay province is one of the important cities in Turkey in terms of cotton production area. According to TSI data, in 4.160.098 da of field; 2.100.000 tons of cotton, 1.260.000 tons of cottonseed, and 756.000 tons of fiber were produced in Turkey by 2016. Hatay province has 11,54% of it's share in Turkey's total cotton production area, and it's has 10,57% of it's share in cotton, cottonseed and in fiber production in Turkey. The primary data of the study were obtained from 136 agricultural enterprises by using the Simple Random Sampling Method with a 95% confidence interval and a 5% average deviation. According to cotton production function analysis results, total elasticity coefficients (Sigma beta(i)) was found as 0,976. This situation indicates that decreasing returns to scale, the result that obtained is very close to constant returns to scale. Among the variables that are in the equation, highest marginal activity coefficients were; seed (X-1) with 13,64 and fertilizer input (X-2) with 4,18. Considering Marginal Rates of Technical Substution, comparing to energy (X-3) factor, ground rent value factor (X-7) was found being used that closest to economic optimum (0,98).
