Abstract
This study was undertaken to identify trends of; Coffee (Coffea Arabica L.) productivity, area of production and numbers of holders of coffee in Ethiopia. Data of; annual coffee yield, area of production and numbers of holders of coffee in Ethiopia for the period 2006/2007-2017/2018 were collected from Central statistical Agency (CSA).

Moreover country level annual total amount of coffee Production were showed significant increasing trend by the factor of 219787.1 qt/year over the study periods. Despite expansions of coffee production area coverage and increasing numbers of holders in the country, however, the trend of coffee productivity in the country showed non-significant decreasing trend by the factors of -0.176 qt/ha per year for study periods. Therefore, the author of this work have recommend that, land suitability of this crop at which it has been expanded in the country and others reasons behind decreasing productivity of this crop has to study DOI : 10.7176/JNSR/9-15-01 Publication date : August 31 st 2019
