The increase in production is due to increase in yield.Įthiopia is the only country that produces teff (Eragrostis tef) in the world, but the production of teff is still low compared to other cereal crops. And instability index of Teff during the study period are also low. And the result showed that, the relationship between area and production was significant. Further, the study fitted the linear regression to test the dependency of production of Teff on its respective area. The growth rate in area, production and yield was statistically significant at 1% significance level. Analysis of annual compound growth rate in production showed a positive growth rate per annum that is greater than the growth rate in yield and area. The study analyzed that, a positive annual percentage change was experienced in yield production and area over the study period. The study is based on secondary data of Teff production, area and yield for the period of 2000/01 to 2014/15 using the compounded annual growth rate, cuddy Della Vally Index and Decomposition analysis. The present study is related to the trends, growth and instability of area, production and productivity of Teff in Ethiopia.
