AGROFORESTRY - SOUTHERN PINES AND SUBTERRANEAN CLOVER CULTURAL TREATMENTS

Agroforestry research in central Louisiana, USA, examined the effects of agronomic cultural treatments (disk, chemical, hay, and hay-graze) on subterranean clover (Trifolium subterraneum L.) yields and slash pi ne (Pinus elliottii Engelm.) and loblolly pine (P. taeda L.) survival and growth. Cultural treatments appear necessary for successful produc tion of subterranean clover in tame pastures, especially for early fal l forage growth. Subterranean clover yields in volunteer swards during spring were highest on the disk and chemical treatments. Generally, p ine survival and growth during the first 5 years following tree establ ishment were not affected by cultural treatments.
