A major constraint in increasing soybean production in the developing countries is the availability of inoculum to small scale farmers in the remote areas of the country. This group of farmers also lack adequate storage facilities for the inoculum. This problem is being overcome by developing pro-miscuous soybean varieties in Zambia (Javaheri and Nyemba, 1982; Joshi et al., 1985) and at the International Institute of Tropical Agriculture, Ibadan, Nigeria (Kueneman et al., 1984).
