Abstract

Avocado yields are low when compared to other fruit tree crops, and the Hass cultivar, specifically, possesses an inherent tendency to produce a high percentage of small fruit. The application of thick composted pine bark mulch was investigated as a strategy to increase yield and to alleviate the small fruit problem in this cultivar. Mulched trees showed more prolonged and extensive root growth throughout the duration of the trial. Over three seasons, mulching elevated average fruit yields by 22,6%, and increased mean fruit mass by 6,6%.The number of fruit that were considered highly suitable, and acceptable for export, were increased by 45% and 20% respectively. Initial costs of the pine bark were off-set within two seasons, thus providing growers with a practical means of boosting financial returns, especially since pine bark is considered to have a half life of approximately five years.
