There is no much Information on the effect of newly introduced blended NPSZn fertilizer on carrot seed production .Therefore, this study was conducted in 2019 to assess the effect of blended NPSZn fertilizer on locally used carrot varieties and to evaluate carrot varieties on seed yield of carrot at Hossana, southern Ethiopia. The experiment consisted of five levels of blended NPSZn fertilizer (0, 100, 125, 150 and 175 kg ha-1) and three carrot varieties (Haramaya I, Nantes and royal Chantenay). Randomized complete block design in factorial arrangement with three replications was used. The analysis showed that almost all parameters were significantly (P< 0.05) affected by the main effect of blended NPSZn fertilizer. The crop phenology also showed significant (P< 0.05) differences among the varieties. The highest (17.97, 23.54 and 45.38 g) seed yield from primary, secondary umbels and total yield were obtained from the carrot plant that received 175 kg ha-1 NPSZn fertilizer, respectively. Likewise, the highest seed yield per hectare (1973 kg ha-1) was recorded from the application of 175 kg blended NPSZn fertilizer, which could be recommend for carrot seed producers in the study area and similar environments.
