This report presents optimal harvest data equations (OHDE) calculated for 6 cultivars for apples at 3 locations in eastern West Virginia. In general, the equations predicted the observed harvest date one day better than the technique of using average calendar days for fruit development. The equations also indicated that bloom date was more important for determining the harvest date than the mean temperature during the growing season. Nonetheless, because of variability between equations, the overall usefulness of using the historical approach to the development of OHDE is limited.
