Oats (best for attraction, poor cold tolerance - dies out at 0-10 degrees) or winter wheat (better cold tolerance, high preference), or winter rye (by far the best cold tolerance, lower preference) at 40-50 lbs acre (of any locally available variety) with 20 lbs/acre of crimson clover planted in september is my favorite fall annual shootemup plot. You could add austrian winter peas on larger acreage, but dont bother on a quarter acre, they will never make it.
