Abstract
Fuelwood quality parameters such as calorific value, siliceous matter and basic density of coconut stem wood were determined. The material examined was from non-diseased senile palms of age around 70 years and root-wilt diseased palms of age group 55–65 years, 35–45 years and 15–25 years. Average calorific value of coconut stem wood in air-dry condition was found to be about 16.3 MJ/kg and it compares fairly with that of hardwoods. A highly positive correlation (r=0.96) was obtained between density and calorific value per unit volume. Also, a highly negative correlation was obtained between siliceous matter and calorific value. Upper half of the mature and over-mature palms and 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.
