Excellent weed suppression through allelopathic effect, suffocation, light block. Thick root system will loosen up heavy clay soils for the benefit of soybeans. Returns numerous minerals, especially phosphorous, to the benefit of soybeans. Low maintenance crop with no additional input costs. Buckwheat is very unpredictable.
Yields can vary for many reasons beyond the farmer's control.
Sew about 40 to 50 pounds per acre, lower seeding rate promotes more branching and flowering. Select seeding date to avoid flowering during hot summer days and nights as the excessive heat interferes with pollination and reduces yield. Popular seeding dates are either May or the end of June. Plants will flower in about 4 to 5 weeks. Pollination requires pollinators, but not necessarily honey bees.
