Summary:Farmers in most developing countries store seed potato ( Solanum tuberosum L.) tubers in traditional storage that invariably leads to rapid deterioration in the quality of the seed tubers due to sprouting and aging. Thus, potato seed tubers senesce and are past their prime when planted. A pot experiment was conducted at Sirinka Agricultural Research Centre, in north-eastern Ethiopia, to evaluate the effect of treating seed potato tubers with crude plant essential oil extracts, on the growth and yield of the potato crop. Treatments consisted of seed potato tubers treated with dill weed, spearmint, black cumin and eucalyptus crude essential oil extracts, each applied at 45, 90 and 135 mg kg-1 of potato tubers for one month, plus a control treatment. The control consisted of untreated tubers. Results revealed that potato plants grown from seed tubers treated with oil extracts from dill weed, spearmint, and eucalyptus at 135 mg kg-1, took the longest time to sprout, flower, and tubers to mature. Potato plants grown from seed tubers treated with dill weed, spearmint, black cumin and eucalyptus crude essential oil extracts at 135 mg kg-1 were 23 - 38% taller than plants from the untreated seed tubers. Similarly, potatoes from these treatments had 21 - 89% more numbers of leaves compared to plants from the untreated seed tubers. Crude essential oils from dill weed at the concentrations of 90 and 135 mg kg-1 and eucalyptus at 135 mg kg-1, had the greatest positive effects on growth and yield of the potato crop. Dans plusieurs pays en développement, les paysans conservent les tubercules de pomme de terre ( Solanum tuberosum L.) en stockage traditionnel, ce qui est responsable de la détérioration rapide de la qualité des semences due au vieillissement et au bourgeonnement des tubercules. Alors, les tubercules de pomme de terre vieillissent et perdent leur fraîcheur avant d'être planté. Une expérimentation en pots a été conduite au Centre de Recherche Agricole de Sirinka au North-Est de l'Ethiopie pour évaluer l'effet du traitement des tubercules de pomme de terre avec des huiles essentiels sur la croissance et le rendement la culture subséquente. Les traitements consistaient en l'utilisation des huiles essentielles de la fenouille, la menthe verte, du cumin noir et de l'eucalyptus à différente concentrations (45, 90 et 135 mg kg-1) pour traiter les tubercules de pomme de terre pendant un mois, et un traitement témoin (tubercules non traités).
