- Agronomic: canola, corn, soybeans, sunflower, wheat
- Crop Production: conservation tillage
- Farm Business Management: budgets/cost and returns, agricultural finance
- Natural Resources/Environment: carbon sequestration
- Production Systems: organic agriculture, transitioning to organic
- Soil Management: organic matter, soil quality/health
This research was designed to evaluate tillage, conventional tillage and no-till, and crop management on organic grain production in a rotation of wheat-soybean and rye/crimson clover-sunflower. Despite numerous difficulties, including inability to control weeds in no-till crops, planting sunflower in heavy residues of cover crop, and inability to control major insect pests, we were able to produce crops. However, yields for sunflower and wheat under both tillage regimes were lower than expected for the cultivars used in the study. Yields for both conventional-till and no-till soybean, though, were within the range reported for the cultivar grown in conventional production systems.
- Develop systems of organic grain production that integrate sunflower into traditional grain rotations using either conservation or conventional tillage
- Determine effects of different tillage systems for organic grain production on soil quality and soil physical properties.
- Transfer organic grain production technology to producers, technical service providers, and students.
