Drilled soybeans should be planted at 175,000 viable seeds per acre. Wheat seed should be planted at 1.6 million seeds per acre when planting early and increased up to 2.1 million seeds per acre when planting late. Wheat planting rates are already adjusted for germination. Increase Stand Establishment Uniformity in Corn. Yield losses of 10 to 15 bushels per acre have been attributed to plant spacing variability in corn stands in Indiana and Ohio.
Plant spacing variability begins with the planter.
Follow all adjustment instructions and service schedules listed in your operator's manual. Deciding how deep to plant your seed is one of the most important decisions you will make as uneven emergence can also reduce yields. The correct seeding depth for a given field should be based on the depth of the uniform moisture zone and the 5 to 10 day weather outlook. Seeds should be placed into moisture whenever possible. Adjust closing wheels so that they close the seed furrow properly without exerting excessive down-pressure.
