Abstract
Cotton (Gossypium hirsutum L.) is the main raw material for textile industry and textile products. According to WORSHAM (1989), 90% of world requirement is obtained from cotton fiber and the rest (10%) from synthetic fibers. In Indo-nesia cotton demand increases every year propor-tionally to the demand of textile and textile pro-ducts.

The first study was conducted through survey method with linear programming models as the tool for analysis. Based on the results of the first survey, the second study was arranged in a randomized block design, consisted of three levels of cotton row, three levels of soybean row, and three levels of irrigation systems.
