The Cotton Wizard: A Quantitative Decision Tool For Cotton Variety Selection

Jason Beddow, Emmett Elam and Mario Lopez


 
ABSTRACT

The Cotton Wizard is a computer implementation of a cotton variety selection model intended to assist decision makers in variety selection. The program uses objective data generated by agricultural experiment stations across the U.S. Cotton Belt, or from other sources provided by the program user. The decision criteria for variety selection is based on expected economic return (mean net revenue) of a variety and the variability of returns (coefficient of variation). Total revenue is calculated from lint prices and seed prices, and lint and seed yields. Lint and seed prices are determined by their respective quality characteristics. Adjustments are made for costs which may differ among varieties, such as planting seed cost, and harvest and ginning costs. Users are provided with information on varieties—such as mean net revenue (total revenue - costs), variability in net revenue, and agronomic characteristics—to aid in the decision process. The program is distributed as a Microsoft Windows compatible product.
