Oats - An Excellent Fall Forage in 6-8 Weeks

Oats - An Excellent Fall Forage in 6-8 Weeks

Oats may be one of our most under-used fall forages. It grows fast, thrives under cool fall conditions, has excellent feed value, and can produce over 2 tons of hay or pasture yet this year.  Plus, it dies out over winter, so it protects soil without causing planting problems next spring.

To plant oats, drill about 3 bushels per acre in early August for maximum yield potential.  Plantings after Labor Day may not succeed well due to a short growing season.  A fully prepared seedbed usually is best, but you can plant oats directly into wheat stubble or other crop residues if weeds are killed ahead of planting.  Even flying oats onto corn or bean fields severely damaged by weather or to be chopped early for silage can work, although rye tends to work better for flown-on seed.  Avoid fields with herbicide carryover, and topdress 40 lbs of nitrogen per acre unless the previous crop was heavily fertilized.

With good moisture, oats will be ready to graze about 6 to 8 weeks after emergence.   Calves and yearlings can gain over two pounds per day.  Be careful to avoid grass tetany on lush oat pasture; ask your veterinarian if you should supplement with magnesium. Also, don't suddenly turn livestock out on oat pasture if they have been grazing short or dry pastures.  Sudden respiratory problems can occur.

For hay, cut oats soon after plants begin to dry out following a killing freeze, or cut earlier if plants reach a desirable growth stage.  Oats can accumulate nitrates, so test hay before feeding.
