Abstract

The annual diameter increment in Artocarpus hirsuta, Dalbergia latifolia and Grewia tilaefolia were studied in the mixed deciduous forests of Wynaad, over a period of 16 years. The increments were found to be 0.48 cm, 0.34 cm and 0.33 cm respectively over the range of diameter studied. Artocarpus hirsuta take 137 years, Dalbergia lotifdia 148 years and Grewia Ioaefolia 168 years to reach 60 cm of D.B.H. in these forests.

Abstract

Anthocephalus chinensis plantations raised at 5 different spacings viz, 6'×6', 6'×12', 12' × 12',8 5'×8.5' and 12'×12' (Quincunx) were studied to identify the spacing that gave the best growth. The spacing of 12'×12' is found to give best growth; besides 8.5'×8.5' is also found to give similar growth rate and having additional advantage of having more number of trees in a given area.

Abstract

The effect of time of emergence of seedlings on seedling vigour is studied in this paper. It is found that the sooner the emergence, the poorer will be the vigour and the later the emergence of seedlings, the greater will be the vigour of seedlings. Among the seed sources tried, the best one is identified through statistical analysis of the data recorded.

Abstract

Sandal is perhaps the most valuable wood in India. The price of sandal heartwood at the turn of this century used to be Rs. 365/- for a ton which rose to around Rs 80,000/- per ton at present. The production is however depleting very steeply. Sandalwood production and prices of Karnataka and Tamil Nadu are taken up for the study. It is found that the production in Karnataka is decreasing at a rate of 7 per cent per year and increasing slightly from year to year in Tamil Nadu at a rate of 2 per cent. The price of sandalwood is found to increase at a rate of 10 per cent per year per ton. Cause or depletion and remedial measures are given.
