Abstract:

Tef is the major crop grown in Ethiopia and the study area. However, its productivity is low mainly due to limited use of improved varieties and low soil fertility as result of intensive soil erosion and long history of cultivation. Therefore ,a field experiment was carried out on a farmer’s field at Gelan Akaki district during the 2018 main cropping season (from July to November 2018) to assess the response of tef varieties to blended NPSB fertilizer rates and to identify the economically feasible rates of blended NPSB fertilizers for the tef varieties. The treatments consisted of factorial combinations of three varieties of tef (Qunch, Kora and Dagim) and five levels of blended NPSB (0, 50, 100, 150 and 200 kg ha-1 ) fertilizer rates. The experiment was laid out in randomized complete block design in a factorial arrangement with three replications. All the plots were supplemented with 46 kg N ha-1 in the form of urea. Analysis of the results revealed that days of panicle emergence (DPE), days to physiological maturity (DPM), plant height (PH) and grain yield (GY) were highly significantly (p
