Seedling emergence and stand establishment of carrot seeds are often slow and erratic which results in low productivity. Poor seed quality together with lack of pre sowing seed treatments and improper irrigation management can be mentioned as the major factors that influence the production and productivity of carrot. The present study was, therefore, carried out with the objective to evaluate the effects of different seed priming techniques on establishment, growth and yield of carrot (Daucus carota L. cultivated variety Nantes) exposed to different irrigation intervals, under field conditions at Gerado, South Wollo, Ethiopia. Four seed priming treatments (no priming, distilled water as hydro priming, potassium nitrate as halo priming and gibberelic acid treatment as hormonal priming) and three irrigation intervals (4, 7 and 10 days) were combined in split plot design with three replications where the irrigation intervals were assigned to main plots and the seed priming techniques to sub plots. The results indicated that except, the interaction effects of priming techniques and irrigation intervals on number of leaves per plant the main as well as interaction effects of seed priming and irrigation interval significantly affected most of the tested parameters. Distilled water treatment in seven and ten days irrigation intervals recorded the highest marketable carrot root yields of 33.73 t ha and 30.63 t ha- 1 respectively. Moreover, distilled water treatment in seven days irrigation interval gave the highest net benefit of carrot (858476.21birr). The same treatment combination also recorded the highest marginal rate of return (4255.80%) which can be recommended for economical production of carrot in the study area and other similar agro-ecologies. However, as the results are limited to one location and season, repetition of the study in multi-location and season is necessary to come up with a sound conclusion and recommendation.
