Gene Krenzer, Oklahoma Extension wheat specialist, has compared 34 varieties. On average, there have been 22 days from the time the earliest variety reached FHS until the latest. This information, combined with research data on when different varieties head, can help producers select the wheat that best fits their needs. Good-quality seed is essential in getting a quick stand, which improves early season forage production. OSU studies have shown that forage production potential may be reduced by 1,000 pounds per acre for each two weeks of delay in emergence during August and September.
Soil testing helps gauge fertilizer needs, especially for phosphorus and potassium.
The rule of thumb is to apply 2 pounds of nitrogen for every bushel of yield goal. Then, after removing cattle, topdress the crop with 30 pounds of nitrogen for every 100 pounds of gain per acre. In Oklahoma, the gain usually averages 100 to 200 pounds per acre. This means 30 to 60 pounds of supplemental nitrogen would be needed after cattle are removed. Gribble warns not to neglect phosphorus because it promotes early forage production.
