Agriculture, as the main user of available fresh water in the Pacific Northwest, faces persistent pressure to be efficient. The intent is to maximize the water use efficiency of crops by minimizing the amount of water used for production by reducing irrigation levels and minimizing water losses. This study evaluated the impacts of reduced, sustained deficit irrigation water management on two specialty oil crops, mint and canola. The study evaluated the yield parameters of native spearmint (Mentha Spicata) and two varieties of canola (Rapier and Athena) over two seasons for the impact of sustained deficit irrigation on the quantity and quality of yields and yield characteristics. Sustained deficit irrigation is shown to be adaptable to water constraints for canola and spearmint with potentials to stabilize farm returns by potentially raising the unit price of the oils and byproducts. With this scenario increased price offers, due to improved quality coupled with production cost savings would create a production niche to sustain the Pacific Northwest spearmint and canola farming systems.
