Abstract
The effects of weeds on the oil yield of tea tree,
Melaleuca alternifolia (Maiden and Betche) Cheel, were
examined in 6 field experiments. Tea tree is grown in plantations as a coppice
crop, being annually harvested for its leaf oil. Plots were maintained with
and without weed control between successive harvests. Weed interference
significantly reduced leaf biomass yield of regrowth tea tree in 5 of 6
experiments, with a mean yield loss of 25%. Yield losses ranged from 9
to 47%, and these were correlated with weed biomass remaining at
harvest. Weed interference did not significantly affect leaf oil
concentration, or its chemical composition.
