Understanding Nitrogen Use in Cabbage: New York Study, 2014-2016
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program

The Cabbage Research and Development Program (CRDP) funded a three-year project to investigate various aspects of nitrogen dynamics in cabbage from 2014 to 2016. Following are highlights from this work.
The project involved two on-farm small-plot trials, a grower survey and four case studies. Nitrogen application rate, application timing, crop use and nitrogen left in the field at harvest were all investigated. It appears that 150 lb per acre of total nitrogen applied in a split application is the most appropriate and efficient use of nitrogen fertilization in cabbage.
