Abstract: Field and laboratory experiments were conducted at Holeta Agricultural research center with the objective to determine the effect of halo, hydro and hormonal priming on germination, seedling growth seedling vigor and seed yield of carrot crop. The treatments consist of one carrot variety (AUA) and priming media KNO3(2%), Salicylic acid 2% and distil water at timing of 12, 24, 36 hour and dry seed as control treatment. The experiment was carried out using Randomized Complete Block Design for field experiment in three replications and Completely Randomized Design for laboratory experiment in four replications. Analysis result showed that highly significance difference was observed among the priming treatments for improving days to fifty percent emergence, significant difference was observed for days to maturity and no difference observed for the other field parameters. Similarly, highly significant difference observed for speed of germination, standard germination, seedling length, vigor index one and significance difference was observed for vigor index two. Carrot seed primed by Salicylic acid for 24 hr. took significantly lesser days 13 days to 50% emergence and carrot seed primed by KNO3 for 24hr, by distil water for 12 hr and 24hr significantly reduced days to number of 50% emergence by 23.08% over control treatment. from field and laboratory experiment priming treatment improve most of the measured variables of carrot seed over the control treatments. Concerning priming medias both at field and laboratory experiment hydro priming was better followed by hormonal and halo priming on most of the measured parameters.
