Abstract:
Tef is one of the mostly important food grain sources of livelihood for farmers of the Aneded
district in North Western Ethiopia. Nevertheless, the productivity of the crop is noticeably low
due to limited use of improved variety and inappropriate use of rate of nitrogen fertilizer.
Therefore, the field experiment conducted in Aneded district during 2016/17 main cropping
season to evaluate the response of tef varieties to different rates of nitrogen fertilizer. It 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. The
collected data subjected to statistical analysis by using SAS 9.1 and mean difference compared
by DMRT at 5% level of significance. From this finding, Quncho variety and the highest rate of
nitrogen (97.5 kg/ha) was identified to be the high yielding (3.68 t/ha) and economic nitrogen
level with acceptable marginal rate of returns and as a result, 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 |
