| Abstract: | Four forage management treatments, bahiagrass, common bermudagrass, Coastal bermudagrass, and timber only were established
in 26-year-old loblolly pine plantation. Pine growth data were collected in 1984, 1990, and 1995, and forage production was
evaluated at 21-day intervals from April to October from 1991 through 1995. Forage management practices improved timber production,
increasing five-year merchantable volume growth by 13 m3 ha-1. Mean five-year forage crop yields differed among treatments (P = 0.05) with daily dry matter yields averaging 39, 46, and
48 kg ha-1 for bahiagrass, common bermudagrass, and Coastal bermudagrass, respectively. Forage nutritional quality did not differ among
forage crops. Forage management treatment future net values were computed for a 5% real interest rate. Although the future
net value for bahiagrass and common bermudagrass exceeded Coastal bermudagrass, the mean forage crop future net value was
similar to the timber only treatment.
