Visual cues of crop stress are among the most basic observations that can be used to manage irrigation in orchard crops. However, these cues can be somewhat subjective and are often expressed after plant stress is higher than desired. Measuring midday stem water potential (SWP) using a pressure chamber is a quantitative method for evaluating plant water status. Continue reading →

Spring freezes and reduced water supplies have significantly affected production. When considering late-season irrigation strategies for prune trees, both the current and following season’s crops must be considered. Continue reading →
