Direct Sowing as an Establishment Technique for Pinus radiata

Abstract

Experiments to test direct sowing as an establishment technique for Pinus radiata are described and discussed. It is concluded that sowing should be restricted to sites which can be established by planting without difficulty; that seed should be treated for dormancy; and that only repellent-coated seed should be used. Spot sowing proved an economically attractive method which deserves much wider attention. Costs of spot sowing operations are given and compared with planting costs. Sowing to establish dense stands is shown to be feasible but wasteful of seed. Burning is recommended before sowing to establish dense stands.
