Abstract Background The need for adopting improved rice technologies and practices has become more important in Ethiopia as the national self-sufficiency gap has increased. This article examines the adoption level and factors governing the adoption of improved rice technology packages and practices using data collected from 594 rice-producing household heads in Ethiopia. A multivariate probit (MVP) model involving a system of five equations was used to assess the determinant for the decision to adopt improved rice technologies and practices. Results The results showed that the adoption levels of improved rice varieties, row planting, recommended rate of urea fertilizer, recommended rate of DAP/NPS fertilizer, and recommended weeding frequency was 24.4%, 23.4%, 40.9%, 38.6%, and 52.4%, respectively. The model results attested that improved rice production technology packages are complementary. This finding implies that farm-level policies that affect the use of one improved agricultural technology can have a positive effect on the other technologies. The various demographic, socioeconomic, and institutional variables were found to influence the decisions to adopt different technologies of improved rice technology packages with different signs. Conclusions Therefore, the government should devise ways to ease the accessibility of improved seeds and fertilizers along with the introduction of labor-saving technologies to promote row planting and achieve wider adoption of the technologies. Policies and interventions that are informed about such factors are required to accelerate the adoption of improved rice technology packages in Ethiopia to realize green revolution and secure self-sufficiency of rice sustainably.
