The global demand for mushrooms is on the rise due to their pharmaceutical, nutraceutical, and cosmeceutical benefits, as well as the development of downstream industries. This has prompted agropreneurs to take part in this herbal industry. Local mushroom supply levels, however, are inadequate because of the lack of cultivators. In a bid to boost the local mushroom supply and to encourage the participation of agropreneurs, the National Agrofood Policy (2011-2020) has included the mushroom industry as one of the country’s high-value industries. The government has focussed its attention on this in order to motivate agropreneurs to cultivate mushrooms. Therefore, research has been carried out to identify the types of mushrooms that are on offer, and to investigate what are the factors that drive agropreneurs in Johor to cultivate mushrooms. Johor was chosen for this study because it has the highest number of agropreneurs, as well as mushroom production in the Malaysian mushroom industry. The research utilised both qualitative and quantitative approaches. The triangulation method, which includes questionnaires, interviews, and observation was carried out on 42 respondents. The data shows that all agropreneurs in Johor supply grey oyster mushrooms ( Pleurotus pulmonarius ) because of the high local demand for it, while fungus mushrooms ( Schizophyllum sp. ) are cultivated in small scale. The research indicates that the agropreneurs are inclined towards this industry because of their interest in this crop. Additionally, they are attracted by the promise of high returns within a short term; the success of fellow cultivators; incentives provided by the national policy; or because they took over the family business. To sustain the interest of agropreneurs in this industry, the government should provide integrated, effective, and holistic motivation through various incentives and by offering expert advice. The increase of local agropreneur participation in mushroom cultivation will boost local supplies, lessen our dependence on imported mushrooms, and provide supplies for the export market.
