      abstract = {Kenya has made significant strides in developing hybrid  maize varieties and is considered a success story in the  region. The number of hybrid varieties released per year  has been increasing but average maize yields and  consumption have been declining resulting to food  insecurity in both urban and rural areas. Past studies  evaluated the impact of hybrid maize on income inequality  and poverty but none on food security impact in Kenya.   This paper used representative data from 1344 households to  answer this question. Three food security indicators are  considered: Months of adequate household food provisioning  (MAHFP), household food insecurity access scale (HFIAS)  scores and household food insecurity access prevalence  (HFIAP). The paper applies two step gmm2s specification and  corresponding tests for relevance and validity of the  instruments. Household food insecurity prevalence is  assessed using generalized ordered logit model. Food  security increase with hybrid maize adoption, maize sales,  wealth, education, access to financial services and  irrigation water but decline with household size. Food  security also vary with agro ecological zones. Hybrid maize  adoption reduces the risk of being moderately and severely  food insecure by 5% and 13% respectively. Results suggest  the need for policies that enhance hybrid seed adoption,  surplus production, education, improve welfare and promote  family planning.},
