This study aims at identifying the impact of production and marketing policies on the contribution of the cotton crop in the total exports of Sudan in the period from 1970 to 2012.

The study used the descriptive analytic method and the statistical quantitative method and adopted three variables as potential independent factors that have an impact on the contribution.

Those factors are: cost and production that represent production policies and economic liberalization that represents marketing policy.
