A simulation model for cotton harvesting was developed on an electronic spreadsheet. It was used to evaluate early, standard, and late maturing cotton using five years of weekly data on days fit for fieldwork and prices received by farmers. Days fit and hours per day in the field exhibit downward trends during the harvest period, implying that early maturity requires less time to harvest. Furthermore, prices received and yield also generally decline throughout the harvest period. Therefore, more yield at a greater price can be derived by completing harvest in a shorter time period. The simulation model used these relationships to demonstrate the benefits of early maturity over the other two alternatives. Early maturity had an average increase in revenue of $33.80 per acre over standard maturity and $84.60 per acre over late maturity.
