security and socio-economic stability. This study assessed the impact on adoption of improved 

maize varieties on farmers‟ livelihood in Sumaila Local Government Area of Kano State, 

Nigeria. The study examined the socio-economic characteristics of the maize farmers, determined 

adoption rate of improved maize varieties by the farmers, determined the factors influencing
