Abstract

Variation in the productivity levels of teak plantations raised during the last one rotation period was examined with the data generated from Working Plan Reports of the Forest Department. There were distinct regional differences in productivity with respect to the proportion of area under different site quality classes. The range of variation could be partitioned into three natural levels of low, medium and high productivity and regions falling in these classes could be identified through clustering procedure. The average expected yields worked out for the three clusters showed large difference which have implications on the management of these plantations
