This paper investigated factors influencing value addition agricultural choices of smallholder farming agribusinesses in the Gauteng Province, South Africa, using the Ordinary Least Squares regression model. The study used randomly sampled data collected from 102 smallholder farmers by the National Agricultural Marketing Council and the Gauteng Department of Agriculture and Rural Development. Four types of value addition were identified, namely postharvest, food preservation, milling, and post-slaughter. The results revealed that the number of people in the household, permanent workers, and access to training influences smallholder farmers’ choice of post-harvest, food preservation, and post-slaughter value addition. Besides, milling value addition is influenced by the size of the farm, grain, and livestock production, together with access to information and training. These results call for government intervention in promoting agro-processing and value addition activities to encourage farmer participation, income generation, and poverty alleviation, thus improving the farmers’ livelihoods.
