Before developing a variable-rate seeding prescription, you first need to delineate a field into different management zones, or regions of distinct crop yield potential.

In the context of precision agriculture, management zones are field areas possessing homogenous features for landscape and soil properties, which lead to similar crop yield potential and input-use efficiency for seed, nutrients and water.

This edition of Crop Insights provides a discussion of the steps involved in conducting Multi-Year Yield Analysis (MYYA) as well as the process for using MYYA to develop management zones for variable-rate seeding prescriptions.
