Phytophthora Root Rot

This is a fungus that survives in the soil and can affect soybeans from seedling stage to maturity.  Prevalent in heavy clay soils with poor drainage.

Phytophthora tolerance scores indicate the ability of the soybean to withstand Phytophthora pressure under field conditions.

Planting Population

The percentages given in this guide are recommended population levels relative to the current field/farm planting populations. To calculate planting rates, multiply the population percentage by your current field or farm average population.

Protein

Values can vary widely by growing season and region.  

Protein content (at 13 percent moisture) as determined by evaluation in Stine’s Elite Yield Trials.

Pubescence Color

All soybean plants have "hair" growing on the stem and leaves. This "hair" is referred to as pubescence, which expresses a definite color. Most soybean plants have either gray, tawny or light tawny colored pubescence. A soybean plant's pubescence color has no influence on yield or other agronomic characteristics.
