Increased interest in winter canola (Brassica napus L.) production throughout the Southern Great Plains has brought fourth several issues regarding production management. Very little research on N management has been conducted in the southern Great Plains. The objectives of this study were to determine the optimum time (fall vs. spring) and N application rate for winter canola (pre-plant plus top-dress). To evaluate N management locations were established in south-central Kansas and north-central Oklahoma. Treatments included various rates of N applied either at pre-plant or top-dressed or in combination. Nitrogen application rates ranged from 0 to 168 kg N ha^-1. Grain yield will be measured in June to determine the optimum N rate and time of N application.
