The above two Tables indicate a decline in productivity in successive periods in all operations without considering the year of planting. Can this mean a decline in management effectiveness over time? The data was insufficient to answer the question either way. But the possibility of such an eventuality cannot be ruled out. Nevertheless, considering the low levels of productivity achieved in Nilambur Divisions, it is very essential to give more importance to efforts for increasing the productivity of teak plantations by enhancing the quality of management inputs. It would have been ideal if the productivity level remained stable and closely related to the site quality of each pltintation as determined from the top height. In that case, a more refined method of fixing the economically optimum rotation for each site quality was possible. Table 3.12 showed high variability between the site quality of plantations and the level of yield obtained in different operation in selected plantations. Even among the different operations in the same plantation there was marked variation in yield. In this situation an exercise in proposing a rotation age based on the site quality is meaningless. The primary requirement is to find out the reasons for the low productivity and the variation in yield levels. It is beyond the scope of this study to address this problem. Remedial measures will necessarily have to be based on the causes for the low yields. Manipulation of the rotation age and its associated change in thinning schedule without a detailed management evaluation will only complicate matters. Till such a time, the current thinning schedule and rotation age should best continue unchanged. 44
