Optimizing Nitrogen Management for Processing Sweet Corn Production on Fine-Textured Soils

READ FULL ARTICLE

Start Date: 2014

Principal Investigator: Carl Rosen

Organization: University of Minnesota, Department of Soil, Water and Climate

Status: Ongoing

Background Information:

The availability of new sweet corn varieties with higher nitrogen (N) efficiency means researchers should revisit N recommendations for non-irrigated sweet corn production. This research also examined the impact of split N applications, as well as “smart fertilizer” products like coated urea, on sweet corn yields.

 

The specific objective is to determine the effects of N rate/rate/timing, hybrid, plant population density, and planting date on sweet corn yield, N uptake, and residual soil N

Key Findings:
