Abstract

The calorific value, siliceous matter and basic density of coconut stem wood were determined in healthy palms aged about 70 yr old and in root-wilt diseased palms 55-65 yr, 35-45 yr and 15-25 yr old. Av. calorific value of coconut stem wood in air-dry condition was about 16. 3 MJ/kg, which compared favourably with that of hardwoods. A highly positive correlation was found between density and calorific value per unit volume. There was also a highly negative correlation between siliceous matter and calorific value. The upper half of the mature and over-mature palms and the full length of young palms which have been affected by root-wilt disease could be used as a fuelwood of adequate heating value or converted into charcoal
