Abstract

Weeds are continuing to create problems for vegetable growers more than ever before due to climate change, frequent cultivation, and the evolution of herbicide resistance. Weeds not only decrease vegetable yields but also reduce their quality. This case study aims to investigate weed management strategies, their strengths and weaknesses, and, the scope for improvements in a small-scale vegetable garden in Australia. The Armidale community garden in the New England region was selected for this study because of its wider types of vegetable production. The data was collected by observing and, taking an in-depth and unstructured interview of the convener of the garden. The study showed that the growers only use non-chemical weed management strategies to tackle the predicament. Mechanical and cultural methods including mulching, hand weeding, tillage, and grazing are mainly used to manage the weed infestation in the vegetable garden. Among them mulching with wood chips and hand weeding were considered more effective in minimizing the weed competition during the critical periods of crop development but they could not reach a satisfactory level. Thus, further improvements by integrating several approaches simultaneously are needed to control weeds more effectively and economically. The outcomes of the study will benefit both conventional and organic vegetable producers as well as researchers to keep weed populations at a manageable level.
