Sunflower, a relatively new crop for Vermont, has the potential to add value to a farm operation in the form of fuel, feed, food, and fertilizer. However, pest pressures, including weed competition, have limited the yield potential of Vermont sunflower in the past. The practice of interseeding, or planting cover crops between rows, could limit the early-season weed pressures and allow for a competitive advantage for sunflower, increasing yields and quality. Crops like clover, tillage radish, and annual ryegrass may also benefit long-term soil health and decrease expensive inputs by adding organic matter and nutrients into the soil.
