Summary: The objectives of this project were: 1. Continue data collection on bloom phenology and fruit growth for selected sites and cultivars to enhance model accuracy and vigor. 2. Continue refinement of statistical models for bloom phenology and fruit growth. 3. Develop physiological-based models for bloom phenology and fruit growth of apples. 4. Implement and evaluate models as decision support aids on the AgWeatherNet portal using industry beta-testers. 5. Improve model/portal user interface based on feedback from beta-testers and other stakeholders.
