Irish potato is the second most important food crop in Kenya after maize (Kaguongo et al., 2014). Potato production in Kenya is expected to grow, as farmers are being encouraged both by climate shifts and by the government to diversify their production from reliance on maize. Many farmers are opting to grow potato because it is fast-maturing compared to maize and can be used to bridge the gap during shortages of the staple grain (ibid).
