2021 Extension Course


 2021 Principles of Fruit & Nut Tree
Growth, Cropping & Management

April 19 - April 23, 2021

Class Details

Due to UCD campus directives, the 2021 Principles of Fruit & Nut Tree Growth, Cropping & Management will be held remotely. A Zoom link will be provided to registrants.


Understanding the fundamentals of tree biology is essential to making sound orchard management and business decisions in the tree fruit and nut industry.  However, access to educational courses on basic fruit and nut tree biology, and how it relates to agronomic practices, is limited. Our course incorporates lectures and field demonstrations to provide information on all aspects of basic plant biology and the relationship between plant biology and nuts and fruit orchard management.

Our course includes five days of instruction. Each day will have 4 hours of synchronous instruction, with supplemental asynchronous video instruction, and question and answer sessions with our instructors.

Nut and Tree Fruit Education Program
