On-farm research was conducted in Zambia between 1984 and 1987 to examine the performance of an imported bean variety and identify management practices that could result in higher and more stable yields and to examine their economic feasibility for risk averse smallholder farmers. Results showed that the Brazilian bean variety Carioca was superior to the local variety tested in terms of yield, net economic returns and reliability of performance, especially when used in combination with fertilizer and insecticide.
