Varieties resistant to diseases or adverse soil conditions of the intended field. Date of maturity. Several varieties with different maturity ratings may reduce harvest losses. Planting as early as possible is often recommended to reduce pest pressure and maximize yield. A good canopy formed early in the season produces higher yields.
Lodging is reduced under higher plant densities.
Cost of seed must be considered. Desired population at harvest. Average stand loss for the field. Germination rate of the seed. Soil injection of nitrogen-fixing bacteria is not recommended unless the field has not grown soybeans within the last five years.
