玉米是南部非洲大部分地区的主要主粮作物，在一些地区占据主导地位，以至于 80% 以上的小农土地都种植玉米。大豆被认为是一种有潜力满足种植制度多样化需求的作物，有助于克服普遍存在的土壤肥力限制，并可为小农提供创收机会，同时解决家庭的营养安全问题。津巴布韦在 1996/97 种植季节发起了一项举措，以测试大豆作为潜在小农作物的潜力。大豆生产从第一年最初的 55 名农民迅速扩大到三年后估计有 10,000 名农民。从那时起，大豆自发地传播到津巴布韦降雨量较高地区的大多数小农地区。由此，该倡议帮助大量小农种植大豆，打破了津巴布韦长期以来认为大豆不适合小农种植的观念。
Maize is the dominant staple crop across most of southern Africa it is so dominant in some areas that more than 80 per cent of the smallholder land area is planted with maize. Soyabean was identified as the crop with a potential to address the need for diversifying the cropping systems, which could assist in overcoming the pervading soil fertility constraints and could provide smallholder farmers with an opportunity to earn income while also addressing the nutritional security of households. An initiative was launched in the 1996/97 cropping season in Zimbabwe, to test soyabean as a potential smallholder crop. From an initial 55 farmers in the first year, soyabean production expanded rapidly to an estimated 10,000 farmers three years later. Since then, soyabean has diffused spontaneously to most smallholder farming areas in the higher rainfall zones of Zimbabwe. Thus, the initiative has assisted a large number of smallholders to grow soyabean, and exploded a long-held belief in Zimbabwe that soyabean is not a suitable crop for smallholders.
