Experimenting with Soybean/Grass Combinations for Forage
by Michael G. Bertram
Marshfield Agricultural Research Station
- Possibilities of feed shortages exist.
- 500,000 alfalfa acres winter killed in Spring 2003
- Limited research on soybean mixtures.
- New forage oat and forage soybean varieties available.
- Limited pearl millet research in central Wisconsin.

- Late oat planting is risky. It is a better option to plant early.
- Soybeans didn’t change oat quality. Peas are a better choice to enhance yield and protein.
- Forage oats didn’t improve yield over a conventional variety with late planting.
- Pearl millet and BMR sorghum sudangrass both had good potential, but pearl millet generally yielded less and was more dependent on good growing conditions.
- Soybeans may enhance quality in PM and BMR, but results were inconsistent.
- Group 1 soybeans generally yielded less than Group 2, which did not differ from Forage.
- Soybean quality did not differ and was similar to alfalfa, although protein was low.
- These are a few of many options producers could consider when short of forage. Corn silage has a much greater yield potential.
