Abstract
It has been demonstrated that an increase in crop yields significantly reduces poverty. Agriculture in Ethiopia is the foundation of the country’s economy, accounting for more than half of the Gross Domestic Product (GDP). The main objective of the study was to identify non-climatic factors significantly contributing to cereal crop yield in Ethiopia using the data obtained from the 2019/2020 agricultural survey provided by the Central Statistical Agency. In this study, Analysis of Covariance (ANCOVA) and dummy variable regression have been employed to identify non-climatic factors significantly contributing to cereal crop yield in Ethiopia and determine if there is a statistically significant difference between the factor levels of the categorical predictor variables on the mean response variable (average yield of cereal crops measured in kilo gram). The study results showed that seed type used, DAP, area size, and the interaction of DAP and area size were significantly contributing to the change in the mean amount of cereal crop yields in Ethiopia, even though there are regional variations in the factors/variables. Policymakers, the Ethiopian Ministry of Agriculture, and/or all concerned stakeholders should facilitate the accessibility and availability of improved seed and DAP to all farmers so that crop yield is increased and the demands for agricultural products of the country are met.
