The goal of this case study was to investigate the economic feasibility of a new enterprise for Southside Virginia farmers to help alleviate problems stemming from a loss of income and excess production capacity of a tobacco greenhouse. Maple liner production in a tobacco greenhouse was determined to not be economically feasible by this study. The control scenario, as well as the sensitivity analysis revealed that maple liner production would yield a loss when produced in a tobacco greenhouse. The breakeven number of plants to be sold was 43% of the cuttings planted, and could exceed 50% under some conditions of the sensitivity analysis. While the maple liner production schedule was determined to be culturally suitable as a supplemental greenhouse activity, the tobacco greenhouse engineering design was deemed inadequate for maple liner production. Modifications were needed to the ventilation and irrigation systems. This economic study was based on a field trial conducted in Halifax County, Virginia.
