Winter canola is quickly becoming an optional rotational crop in Oklahoma's traditional continuous winter wheat program. Several grass control herbicides are labeled in canola that will control most of the problem grasses that commonly plague continuous wheat production systems. There are two accepted methods for harvesting spring canola in the northern United States and Canada (i.e. direct combining and swathing followed by combining several days later.). Although both methods are utilized for harvesting spring canola in the northern Great Plains, climatic conditions in the southern Great Plains may favor one method over another. Therefore the objective of this research was to determine the harvest efficiency of these methods, considering climatic conditions, equipment available, and time availability of the producers. These data will be vital for producers in the next growing season as they use the information as a harvesting guide.
