At the backdrop of the on-going variability in
rainfall, this research used a quasi-longitudinal research
design to assess the effect of rainfall duration on beans,
maize and African nightshade production in Nyando
sub-County, Kisumu County, Kenya. Primary data were
obtained from questionnaires, interview schedules for
key informants, photography, and observation checklist.
Secondary data were obtained from Kisumu County’s
Meteorological Department and Ministry of Agriculture.
Data were analyzed at descriptive and regression levels.
The analytical results showed that longer rainfall
duration positively affected maize crop production (t =
18.82, p < .001) while it negatively affected both beans (t
= -6.04, p < .001) and the African nightshade (t = -8.05, p
< .001) yields. The research recommends that farmers
should put emphasis on maize production during long
rain seasons with minimal production of both beans and
African nightshade for output maximization. More
beans and African nightshade than maize should be
grown in short rains durations to curb climate-related
