Abstract:	The risk associated with new maize technology and the impact of mandatory cotton production on traditional farmers in the Kasai Oriental Region of Zaire were evaluated using stochastic dominance analysis. Net returns for four levels of maize technology for the primary and secondary rainy seasons were evaluated in combination with three staple food crops for four cropping systems with and without mandatory cotton cultivation for the period 1981-1986. The results indicate that cropping systems including new maize technology are first-order stochastic dominant in both seasons, over cropping systems using local maize. Also, the increase in expected net returns for new maize technology appears to compensate farmers for its increased variability; and mandatory cotton production is not risk efficient at current price and yield levels.
