Abstract:

Artocarpus heterophyllus is increasingly being utilised in the furniture industry despite the limhed
information regarding its properties. This study was conducted to e;);:gorise A. heterophyllus
based on its basic density.
from three mature tobtc fronj a farnHeya parish, Budongo
.
Sub-county, Masindi district. From each tree three boks of heig cut at Uiameier
at Breast Height (1.3 ni), 45% tree height and 75% of tree height. The bolts were sawn into
scantlings using through and through method. Specimens for static bc-ieding nnd basic density
tests were prepared according to Lavers (1983). Bending tests were done in accordance with Busing a Testometric AX Universal Testing Machine. Basic density was determined by
the water displacement method. The mean MOE was 6.378 Ninnr\ the mean
Nmm*2 and mean basic density was 458 Kgnr1. Based on
qualifies as light construction timber. However, further research
MOR was 119
these properties, A. heterophyllus
on other strength properties of
A. heterophyllus is recommended for effective utilisation of its wood for structural purposes.
