The risks involved in seven different cultivation systems as regards yield, net margins and net margins per R100 of capital invested were analysed and ordered using stochastic dominance (SD). Mulch systems are less risky than the conventional systems. This finding agrees with those of similar overseas studies. First-order and second-order SD produced enough proof of dominance in order to exercise choices. Thirdorder SD did not provide any additional dominance results. Rank shifts between net margins and net margins per R100 of capital invested occurred.
