Abstract

Hand baiting for rodent control and sowing patch cuttings in December 1965 produced 880 to 2,540 pine seedlings per acre by July 1966. A tractor-drawn drag used to cover seeds in some areas significantly improved germination in one trial. Costs per hundred seedlings per acre for dragged compartments were $1.08 and $1.33; for other compartments: $0.43, $1.14, and $1.88.
