The main objectives of the study are, to describe, analyze and identify possible optimization for the sedentary production systems (jubraka). And to identify the socio-economic factors that affecting the level of production. Primary data were collected using structured questionnaire. A representative sample size of 50 farmers was selected using multi-stage clustered design. Group discussions using guidelines questions were also used to augment information collection. Secondary data were collected from the relevant institutional sources. Descriptive statistics, linear regression analysis (Cob-Douglas function) and linear programming (LP) were applied to analyze the data. From the linear regression the results showed that (land, labor, capital) have positive effectiveness with different significant. The linear programming results also revealed that Dura and Sesame entered the optimal solution. Keywords: sedentary production system, jubraka, socio-economic factors, linear regression analysis and linear programming.
