A Peek at Nitrogen Dynamics in Cabbage: First Year Results

A Peek at Nitrogen Dynamics in Cabbage: First Year Results
In 2013, the Cabbage Research and Development Program (CRDP) made nitrogen fertility one of their highest research priorities. In response, we studied nitrogen dynamics in cabbage with respect to total rate applied nitrogen and timing of application (proportion applied pre- and/or at-planting compared to side-dressed) in order to determine the appropriate use and timing of nitrogen in cabbage in order to improve efficiency, optimize rates, and reduce environmental contamination from nitrogen leaching and/or lodging in following winter wheat crop. In 2014, a small-plot trial was set up in commercial field of storage cabbage (c.v. Constellation) with five rates of total applied nitrogen (31, 66, 132, 197 and 262 lb/A) and three application timings (100:0; 50:50 and 25:75 at-planting: side-dress). To study the variability of available nitrate-nitrogen remaining in the soil at harvest of summer cabbage, a small survey was conducted. Within a period of 8 days between Aug-25 and Sep-2, nine fields of summer cabbage that were either just harvested or being harvested were sampled for available nitrate-N.

Cornell Commercial Vegetable Guidelines Available

The 2019 Cornell Integrated Crop and Pest Management Guidelines for Commercial Vegetable Production are now available!

Written by Cornell University specialists, this publication is designed to offer producers, seed and chemical dealers, and crop consultants practical information on growing and managing vegetable crops in New York State. Topics include general culture, nutrient management, transplant production, postharvest handling, organic production, and managing common vegetable crop pest concerns. A preview of the Vegetable Guidelines can be seen online.

Highlighted changes in the 2019 Vegetable Guidelines include:
  • Updated pesticide options for economically important vegetable crop pests.
  • New pests: beet armyworm in beets; cabbage looper and tarnished plant bug in lettuce and endive; allium leafminer in onions; and Cladosporium, Cercospora, and Stemphylium leaf spots in spinach.
Cornell Crop and Pest Management Guidelines are available as a print copy ($41), online-only access ($41), or a package combining print and online access ($57.50).
