The overall objective of the study was to investigate the production systems of staple food crops such as Maize, Teff and Wheat in specified study areas. The study used multi stage random sampling technique to select 180 potential respondents as sample size for the study. Both primary and secondary sources of data were used. Primary data was collected from sampled respondents using open-ended and close-ended questionnaires. The secondary data were collected from official documents and records. The study used both qualitative and quantitative methods of analysis in which narration, explanation and simple descriptive statistics were applied. This study found that crop rotation has been used by very majority of farmers. Maize mixed farming system is highly used among the major farming systems followed by high land mixed farming system. Planting methods, production and productivity were less although row planting method seems better than broad casting method of planting. There were no modern stores were used which consequently could result high loss of post-harvest. The threshing methods and threshing materials used were primitive and local type which causes losses during threshing. The finding recommends that mechanization of the sector or provision of sufficient farming oxen is indispensable. Further, modern technologies that help to increase the production and productivity of staple food crops and reduce post-harvest losses should be introduced.
