The Pacific Northwest is not facing the same level of challenges around water availability that are front page news in California or the Colorado River, but we are not immune to water-related challenges either and can expect more of those as the climate continues to warm. Ongoing research into practices that can prepare fruit production for these types of challenges while having the potential to also provide other benefits may seem like the pursuit of an unrealistic ideal. But maybe not. Two blog articles published recently describe ongoing research into the effects of deficit irrigation on water use and on fruit quality in cider apples. This kind of research can help determine whether deficit irrigation is a practice worth considering for multiple reasons. Subscribe to to receive alerts when new articles are posted.
