ABSTRACT
The aim of this study was to identify plot size effects on a broadly defined commercialization concept in three regions of rural KwaZulu using discriminant analysis. The division into small and large plot households was based on the mean plot size in each of the regions. A further division was made according to whether or not a household sold agricultural crops. Generally results indicated that the intensity of purchased requisites use was negatively related to plot size, crop sales tended to come from larger plots and households with crop sales tended to make more use of improved technology such as tractor hire and fertilizers. These results compared favourably with those of studies making use of alternative methods.
