Planting Date

Adjusting soybean planting date is one of the most important and least expensive cultural practices you can do to increase yield. If growing conditions are favorable, planting early offers an opportunity to capture the maximum yield potential of a soybean variety.

Early-planted soybeans use a larger portion of the summer’s total sun and heat, and provides an opportunity to plant a longer-season variety.

However, planting soybean early is recommended only when seedbed conditions are good. Planting in wet soils just to plant early – causing soil compaction and poor seed placement – will outweigh any benefit of early planting.
