Another bibliography on teak by Krishnamurthy (1975) shows nine references under the subject head, ‘Economics and economic products from forest’ which again are mostly from Indonesian sources. However, several studies on the various factors influencing growth and productivity of teak plantations are available. They are mostly centred around site deterioration, fire, pest infestation and management issues. A brief review of relevant studies is given below. Alexander et al. (1987) made a study of the soil properties in different site qualities of teak plantations and observed that variation in site quality of teak plantations is influenced by soil parameters such as gravel, sand, pH and exchange acidity. In spite of a detailed search no previous studies on analysing the productivity of teak plantation using data collected from a large region covering all age groups could be located. The problem is compounded by the high variability in the productivity and the wide price spread in the price of poles and logs. A study on the productivity of teak plantations in Konni, Kozhikode, Nilambur and Wyanad <strong>Forest</strong> Divisions have been concluded by KFRI (1979). The study showed that Nilambur Division had the highest productivity among the four Divisions. So far, no studies have been carried out with respect to the site quality status and productivity of teak plantations. This study analyses the current 4
productivity status of teak plantations in relation to the site quality and examines the profitability of teak plantations in Nilambur Divisions. 1.3 Objectives The Objectives of the study are : i. to compile the available information on teak plantations in Nilambur North and South Divisions classified according to different site qualities, ii. to estimate the productivity of teak plantations in Nilambur Divisions, iii. to analyse the profitability of teak plantations in Nilambur Divisions and iv. to discuss the yields obtained in relation to the site quality of plantations. 5
