The main objective of the study is to examine the determinants of households' food security using a logistic regression procedure. Initially the model was fitted with eleven factors of which six were found to be significant and all had the expected signs. These include farm land size, ox ownership, fertilizer application, education level of household heads, household size, and per capita production. The result obtained was further analyzed to compute partial effects and to conduct simulation studies on significant factors. Analysis of partial effects revealed that an introduction to fertilizer use and an improvement in the educational level of household heads give relatively higher changes in the probably of food security. On the other hand, simulations conducted on the basis of the base category of farmers, representing food secure households, revealed that both educational levels of household heads and fertilizer applications by farmers have relatively high potential to more than double the number of food secure households in the study area following improvements in these factors.
