who are expected to have better skills and access to
new information about the improved technology are
working with uncertain production inputs which as a
result affects their yield (Shiyani et al., 2002).
Belonging to a cooperative society was positively
related with the soybean yield. This implies that farmers
who belong to cooperative societies have more
access to information and resources that could help
improve yield. Consistent with this finding are the
studies of Ajammy and Olayemi (2001) and Fleming
et al. (2004).
The results revealed that access to credit increases the
soybean yield. This is because farmers with access to
credit are able to cultivate large hectares of land and
purchase inputs for soybean cultivation which leads to
increased yield.
2 Conclusion and Recommendation
The study highlighted the awareness rate, sources of
awareness, profitability, determinants of adoption and
effect of adoption on soybean yield in Benue state. It
was discovered that soybean production on the
average was profitable. It was revealed that age of the
