Assessing phenology of almonds

Phenology is the study of when particular events occur, with emphasis on the effect of seasonal or climatic changes. It provides useful information to aid in orchard operations. The value of this information is enhanced when measurements are collected in a uniform and consistent manner.

This document describes how to measure phenology of particular developmental stages in almonds, with specific examples of measuring flowering and hull split. A photoscale for stages of flowering and for hull split are included.
