Adaptability Study of Tef Varieties at Mid Land Agro-ecologies of Guji Zone, Southern Oromia

Abstract

Access of improved tef variety is highly limited in different parts of Ethiopia due to inaccessibility of different production factors. Guji Zone is one of such areas where the technologies are not widely addressed and adopted so far. The current study was conducted by Bore agricultural research center to address the objective of selecting and recommending adaptable high yielding, early maturing ,diseases resistant improved tef varieties for mid land agro-ecologies of Guji zone. The experiment was done at three locations Adola on station and two farmers field (Bilu and Kiltu Sorsa). Thirteen (13) improved tef varieties with one local check were used. RCBD experimental design with three (3) replications was used on plot size of 1mx1m. collected data were subjected to analysis using SAS soft ware. Combined data analysis was used to test the performance of the varieties across the testing locations. The result of the study shows that, all varieties revealed significant difference for the selected characters across the locations. Based on the obtained result, two improved tef varieties namely; Boset and Tsedey shows early maturity, up to 10% yield increment than local variety .Therefore, these varieties were selected and recommended for the study area and similar agro-ecologies of Guji Zone.
