博士 该课程旨在满足多样化学生群体的需求，这些学生的统一特征是将生物学原理应用于解决作物生产和资源管理问题的兴趣。该课程的两个主要目标是在学生之间建立一种社区意识，并向他们提供有关农艺和园艺原理以及它们如何在各种实践中使用的知识。
The Ph.D. program is structured to meet the needs of a diverse student body whose unifying characteristic is an interest in the application of biological principles to the solution of problems in crop production and resource management. Two primary objectives of the curriculum are to foster a sense of community among the students and to provide them with a breadth of knowledge about agronomic and horticultural principles and how they are used in a variety of practices. Students will be aligned into one of five areas of emphasis - Agroecology, Crop Improvement, Crop Production Systems, Plant Physiology, and Post-harvest Biology/Physiology - and pursue projects in these cropping systems: Agronomy, Environmental Horticulture, Pomology, Vegetable Crops, Viticulture, and Weed Science. A wide range of study areas can be pursued including: Biotechnology, Breeding and Genetics, Crop Physiology, Floriculture, Horticulture, Integrated Pest Management, Landscape Horticulture, Modeling and Quantitative Systems Analysis, Nursery Production, Plant Growth and Development, Plant Nutrition, Post-harvest Biology and Technology, Precision Agriculture, Revegetation/Restoration, and Water Relations. In addition, students can become involved in Designated Emphasis programs such as Biotechnology.
