摘要

Wild blueberry growers face numerous production perils of which drought and heat produce the greatest losses. Using partial budgets, this research derives stochastic cost estimates of four alternative irrigation technologies that apply supplemental irrigation to wild blueberries. Uncertain parameters related to irrigation water demand are subjected to Monte Carlo simulation to derive the expected distribution of total annual irrigation costs. This study finds that labor and energy intensive systems supply water more cost effectively to Maine producers due to limited overall demand for irrigation water. In addition, the total anrrigation is highly site specific and necessitates spatially estimation of costs.
