approach to building acres and improving production of winter canola in the Southern Great Plains JOSH LOFTON OKLAHOMA STATE UNIVERSITY
Participants Oklahoma State ◦ Brian Arnall ◦ Jason Warren ◦ Misha Manuchehri ◦ Tom Royer ◦ Kris Giles ◦ Kristen Baum ◦ John Damicone ◦ Carol Jones ◦ Josh Bushong ◦ Heath Sanders
Texas A&M AgriLife Resrach and Extension ◦ Paul DeLaune ◦ Clark Neely ◦ Jourdan Bell
Goals and objectives ◦ Evaluate genetic potential of winter canola cultivars ◦ Improve crop management practices ◦ Throughout the season ◦ Planting ◦ Harvest
◦ Improve integrated pest management systems ◦ Canola production ◦ Native and non-native pollinator habitat
Goals and objectives ◦ Evaluate canola production systems impact on system health ◦ Soil health
◦ Extend information gained from these programs to major stakeholders throughout the region

Improving crop management practices
Rotating with wheat Recognition that canola did not perform in no-till
â—Ś Physical barrier? â—Ś Most modern equipment should be able to handle
Could there be another type of restriction?
Rotating with wheat Original greenhouse information ◦ >30% of wheat varieties grown ◦ Varying degrees ◦ Minimized root growth ◦ Clubbed and short roots ◦ Ceased germination
◦ This was shocking ◦ Only greenhouse effect ◦ Lets take it to the field
