African indigenous vegetables (AIVs) have remained underutilized despite their potential benefits in sub-Saharan Africa. This study identifies determinants of AIV adoption among Kenyan smallholder farmers and explores whether farmers' decisions to adopt exhibit a true state dependence. Using four waves of data and a dynamic probit model, we identify the existence of dynamics in farmers' decisions, implying that farmers adjust their decisions using knowledge gained in previous periods. In addition, a gender disparity exists: Female-headed households are more likely to adopt AIVs. This is not due to differences in household characteristics but rather to gender differences, which may be associated with Kenyan culture.
