Objective:

  1. The effects of seed class and seed density on supersweet corn plant stand, plant development, and yield were examined using a single lot of Crisp 'N Sweet 710. Seed class and seed density can be controlled in packaging supersweet corn seed and could provide a means to more reliable plant stand establishment.
