Fact Sheet:

Because the crop is not cold hardy, it will not be grown in the Piedmont and portions of the upper Coastal Plain.

Apply inoculum when planting.

Yields may be improved by splitting the potassium applications (K2O) on sandy Coastal Plain soils. Apply half at spring green up, and half after the first cutting of hay.

When perennial peanut is grown intensively for hay production, apply 10 to 20 pounds sulfur per acre.

The P and K recommendations are for hay yields of 4 tons per acre. If higher yields are expected, apply an additional 15 pounds of P2O5 and 40 pounds of K2O per each additional ton per acre of expected yield.
