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. The white beech or grey teak is a fast-growing tree, growing on volcanic and alluvial soils in areas of moderate to high rainfall. The seeds are enclosed in hard coats and show very poor germination rates in spite of various pretreatments (Joshi & Kelkar 1971, Dabral & Amin 1975, Dabral 1976, Davidson & Fairlamb 1976). The germination rate is low, and teak seedlings need shading. Our results do not fully agree with those of other studies stating that larger teak seeds have better germination Germination in most regions it is 30 to 50%, while in dry regions it is very low about 5 to 10% . DABRAL SL 1976 Extraction of teak seeds from fruits, their storage and germination. A method of extraction is described that uses a modified nut-cracker to split the teak fruit in four longitudinal planes. Seed vigor Seed vigour is defined as "the Sum total of those properties of the seed which determine the level of activity and performance of the seed or seed lot during germination and seedling emergence". Pretreatment involves alternate wetting and drying of the seed. At level 35 Farming, teak seeds may be planted in plant pots with a trowel and watered to become teak saplings..
