ABSTRACT
This study examines the extent to which farmers trained by the Food Research Institute have taken
up mushroom farming and also determines the profitability of mushroom production. Specifically, the
study describes trends in the levels of mushroom production since 1995, the rate of adoption and
dis-adoption of mushroom farming by trainees, the profitability of mushroom cultivation and identifies
constraints to mushroom farming from the perspective of farmers. Trend description involves annual
output of respondents in the Greater Accra region from 1995 to 1999. The profitability of mushroom
cultivation was determined by the use of the Benefit-Cost Ratio ,Net Present Value and the Internal
Rate of Return criteria. The constraints to mushroom cultivation from the perspective of the farmers
were listed and ranked in decreasing order of importance. Results from the study reveal that there
is an increasing trend in production by the individual farmers in the Greater Accra region, and that
majority of the Food Research Institute’s trainees took up mushroom production. The estimates of
the profitability indicators suggest that mushroom cultivation is profitable. The average values of the
B/C ratio, NPV and IRR are 1.35, < z 6,2900.00 and 48.24% respectively. The three most important
constraints found militating against mushroom cultivation are: poor marketing, lack of funding and
scarcity of water, in that order. Some of the means by which constraints to marketing of
agroproducts in general could be removed are: Intensification of market survey and dissemination of
market information to producers and also increase in the proportion of Ghana’s merchandise exports
that are processed. The problem of funding could be solved by the farmers forming savings and
loans associations. Investment in rainwater harvesting and storage facilities is a possible means of
solving the water problem. It is recommended that a similar research be carried out in areas outside
the Greater Accra region of Ghana to assess profitability of the industry nationwide.
