If used only for seed, fescue should be topdressed with 70 to 100 pounds of nitrogen during December or January. Timing of nitrogen applications affects seed yields. Nitrogen applied in the early fall or late summer may not be available at the time it is needed. It may have been metabolized by fall growth or lost through leaching. Phosphorus and potassium levels should be maintained at least in the medium range.
Most farmers find it convenient to apply some each year depending upon usage.
On straight fescue stands, the salt pH should be maintained above 5.5. Since most of the fescue seed fields in Missouri are grazed in the fall or winter, cattle management becomes an important factor in seed production. For maximum seed production, grazing pressures should not be too heavy in August, September and October. Tiller development occurs during this time. After the first of November, grazing pressures may be increased and all growth should be removed by January 15.
