Early June seeding has produced the highest buckwheat yields. No specialized seeding equipment is required for buckwheat although some time may have to be taken for calibrating grain drills that do not have a buckwheat chart. Rotations Cereal grains in a buckwheat sample are undesirable from a marketing standpoint because they are hard to clean out. Unless very good control of these plants can be accomplished prior to seeding, growing buckwheat is not recommended. Avoid growing buckwheat on canola or mustard stubble because of their volunteering habit and competitive nature.
Buckwheat grows well on field pea or dry bean stubble or summer fallow.
Volunteer buckwheat in a succeeding crop may be a problem. Check rotations to see if the crop following buckwheat can be sprayed to control volunteer plants. Fertilization Buckwheat responds well to a balanced fertilizer program, but it is not considered a high nutrient user. A soil test to determine what nutrient levels are present is critical. Early research on buckwheat fertility requirements showed that highly fertile or rich soils should be avoided.
