Abstract
Tef is one of the most important food grain sources of livelihood for smallholder farmers in North Western Ethiopia. However, the productivity of the crop is stumpy due to limited use of improved varieties and inappropriate use of rate of nitrogen fertilizer. Therefore, the field experiment was conducted in Aneded district in 2016/17 main cropping season to evaluate response of tef varieties to different rates of nitrogen fertilizer. To accomplish these objective, the experiment contained factorial combinations of four tef varieties [three improved varieties (Dega Tef, Gimbichu and Quncho) and one local check (Basomure)] and four levels of nitrogen (0, 32.5, 65 and 97.5 Kg/ha) that laid out in Randomized Complete Block Design (RCBD) with three replications was used. The collected data on yield and yield components were subjected to statistical analysis by using SAS 9.1 and mean difference were compared by DMRT at 5 % level of significance. The measured values of growth and yield parameters increased with the rate of nitrogen fertilizer. From this finding, Quncho variety with 97.5 kg N/ha is recommendable for the study area even if it needs to be tested again for complete recommendation.
