Abstract After a discussion of the history of the regeneration methods in teak forests of Java since the end of the 18th century, and also briefly of that in India, regeneration systems for teak were reviewed: A. The Taungya system (in which field crops are grown between the rows of teak one year after planting); B. Growth from young seedlings (the number of seedlings can be increased before clearfelling); C. Interplanting with shade trees for weed control, physical improvement of the soil, erosion control and improvement of soil flora and fauna; if shade trees were leguminous, they improved supply of nitrogen; introduction of a second tree species, of which the best was Leucaena glauca; D. mixed regeneration (completely mixed in rows or in groups).
Descriptions of equipment and methods for the study include assessment of site quality and volume of commercial timber, geological and physical assessment of soil and soil flora. Thorough comparisons follow of 1) methods A and B, 2) method A with (~ A + C) and that without L. glauca, 3) method A with L. glauca (= A + C) and that with other indigenous species. Method A was much preferred to B, method A + C (with L. glauca) to that without L. glauca, and to that with other indigenous species. But close mixture with other indigenous species needed more research. The possibilities of plantations with more species deserved more attention.
