Recent literature on international agricultural extension shows a renewed interest in examining the potential for linking public and private extension initiatives. This study was designed to examine the long-term effectiveness of Mennonite Central Committee's (MCC) extension work with subsistence farmers in Bangladesh and the limitations and benefits of linking this work with public extension services. One-hundred and two farmers who received extension support from MCC during the period 1983 to 1986 were sampled. The findings indicate that MCC's past involvement with these farmers is continuing to have a positive economic impact. High correlations were found between MCC extended production technologies and their contribution to net income levels. However, income from MCC extended technologies has declined following MCC's withdrawal. Farmers highlighted the need for continued technical assistance and access to good quality seed. It was concluded from the study that extension activities of NGOs can be linked with government extension services. Possible opportunities to realize such linkages are indicated.
