“…To press this further, it will be justifiable to seek and have a better understanding of the factors that drive the productivity of the smallholder cassava farmers. Much may have been documented already on the influence of the climatic variables, like temperature, sunshine, rainfall, relative humidity, air, and wind, as well as agronomic variables of soil type, soil fertility and typology, fertilizer, planting materials, planting time, quantity and timing of herbicides, among others, on cassava productivity (Ojiako, et al, 2014;FAO, 2013;Aina et al, 2007). But, in addition to these, it has been concisely argued that knowledge of the socioeconomic and other personal characteristics of the farmers enables planners and policy makers to appreciate and develop more user-friendly policies and strategies that will enhance productivity (Ajah and Ajah, 2014;Ajewole and Aiyeloya, 2004).…”
