Summary: Planter performance is a critical component in setting the foundation for a successful crop season. Environmental and soil conditions can have a significant impact on crop germination and emergence and can either help or hinder development of an adequate crop stand early in the season. Specific planter components and settings can be adjusted to match current conditions in the field and ensure maximized emergence, which will translate to yield in most cases. The main goal of this presentation is to provide information on environmental conditions and planter settings that can affect cotton emergence and yield.
