Abstract:
In Ethiopia, increasing household food security is largely dependent on the adoption of improved
teff variety. The main goal of this study was to examine how the adoption of improved teff variety
affected on the households food security. The data was collected from Gena Woreda of Dawuro
Zone, South West Region, Ethiopia in 2024. The survey consists of 219 sampled teff growers out
of whom 91 were improved teff variety adopters and 128 were non-adopters. The study employed
a two-stage sampling techniques, purposively selecting rural Kebeles followed by simple random
sampling of households. Sample households provided cross-sectional data for the study. The
study employed a probit model and an Endogenous Switching Regression (ESR) model to
investigate the factors influencing the adoption of improved teff variety and the resulting impact
on household food security. According to the findings of the probit model, the adoption of
improved teff variety was significantly and positively associated with the frequency of extension
contact, cooperative membership, and tropical livestock unit. However, the adoption of the
improved teff variety was negatively and significantly influenced by the sex of the household
head and the distance to the market. The impact results from the ESR models showed that if
adopters had not chosen to adopt the improved teff variety, their food consumption score and
household consumption expenditure would have decreased by 3.92 and 7612.77 ETB annually,
respectively. However, if non-adopters choose to change to the enhanced teff variety, their
household consumption expenditure and food consumption score increased by 6030.13 ETB
annually and 0.05, respectively. Additionally, the endogenous treatment effect model results
showed that the adoption of the improved teff variety had a significantly positive influence on the
household food consumption expenditure and score. Accordingly, promoting farmers to
membership of cooperatives, improving frequency of extension contact, creating reliable
information and awareness about improved farm technology, and timely agricultural inputs
supply will increase farmers’ decision to adopt improved teff variety in the area
