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.

African Eggplant Participatory Breeding Kick-Off
March 5, 2026
Join us to learn about the Cornell African Eggplant Research Project and learn how you can participate! African eggplant, also known as Bitterball, Garden Egg, Kittley and other names, is an important crop for many members of our community with heritage from regions such as sub-Saharan Africa, Southeast Asia, and Brazil. Since 2024, the Cornell African Eggplant Research Project has been collaborating with growers and community partners across New York to develop high-quality varieties adapted to the Northeast U.S. In this meeting, we will share information about growing and preparing African eggplant, highlight our research to date, and invite partners to collaborate with us in our 2026 participatory breeding and variety selection efforts.
