Organic agriculture (OA) claims to have the potential to address future ecological challenges in food production. However, there is a need to scale up OA in order to meet increasing consumer demand for organic foods. Against this background, this study examined the factors driving farmers to adopt organic vegetable production (OVP) and how much acreage they commit to it. We used structured questionnaires to gather data from 400 farmers in the northern regions of Ghana. To analyze the data, we used Heckman selection model in comparison to Cragg’s double hurdle regression and standard Tobit regression models. The results show that sex, age, education, extension visits, farmer association membership, the timing of production, and access to marketing information are the key factors influencing farmers to adopt OVP. The farmer's age, land ownership, economic status, and farmer association membership are the key factors influencing how much acreage farmers commit to OVP. In order to expand OVP adoption and the organic share of total cropland, strategies are needed to support farmer associations and encourage farmer participation.

有机农业（OA）声称有潜力解决未来粮食生产中的生态挑战。然而，需要扩大有机农业以满足消费者对有机食品日益增长的需求。在此背景下，本研究探讨了推动农民采用有机蔬菜生产（OVP）的因素以及他们投入的种植面积。我们使用结构化问卷收集了加纳北部地区 400 名农民的数据。为了分析数据，我们使用 Heckman 选择模型与 Cragg 的双栏回归和标准 Tobit 回归模型进行比较。结果表明，性别、年龄、教育程度、推广访问、农民协会会员资格、生产时机、获取营销信息是影响农民采用OVP的关键因素。农民的年龄、土地所有权、经济状况和农民协会会员资格是影响农民承诺 OVP 面积的关键因素。为了扩大 OVP 的采用和总农田的有机份额，需要制定战略来支持农民协会并鼓励农民参与。
