teak plantations
Dear sir,
Initial spacing of teak plantation varies (1.8×1.8 to 4×4 m) depending on many factors as site quality, cost of establishment, thinning regime, small wood utilization, planting system, e.g. agro-forestry, intercropping etc. However, site quality seems to be the priority factor directing the size of spacing in the teak planting programme. Results of 12-year-old spacing trials (2×2, 3×3, 4×4, 6×6 m) Based on this study, a 3×3 m spacing (1,111 trees/ha) has been recommended and used as the routine spacing in Thailand. However, in areas where wider spacing is required for the application of agro-forestry systems or machine weeding, the 4×2 m spacing (1,250 trees/ha) is used. Similar results of spacing trials are reported from India where close spacing of 1.8×1.8m and wider spacing of 3.6×3.6 m are suitable for dry and good (rainfall <1,500 mm) site conditions respectively.
