Carrot is an important vegetable crop in Ethiopia. However, the quality of the crop is low mainly due to low soil fertility and a lack of improved varieties resulting in low yield and low quality of carrot seed. Therefore, this study was conducted in 2019 to assess the effect of blended NPSZn fertilizer and to evaluate high seed-yielding carrot varieties at Hossana, southern Ethiopia. The field experiment consisted of five levels of blended NPSZn (0, 100, 125,150 and 175 kg ha-1) fertilizer and three Carrot Varieties (Hramaya I, Nantes and Royal Chantenay). A complete randomized design with four replications was used for the laboratory experiment, whereas a randomized complete block design in factorial arrangement with three replications was used for the field experiment. The result of the analysis revealed that the main factors (blended NPSZn fertilizer and varieties) had a highly significant (P
