Scholarship applications for the 2023 Principles of Fruit & Nut Tree Growth, Cropping & Management course are open now! The Fruit and Nut Research and Information Center will offer a limited number of scholarships for new and small-acreage Californian fruit-growers.

Nitrogen and Potassium Prediction Model


The Nitrogen and Potassium Prediction Model is now live on the Fruit and Nut Research and Information Center’s website! This robust tool will help growers determine the recommended amount of nitrogen and potassium needed to maximize productivity for pistachio trees.
