Abstract

An experiment was conducted in the fields of a potato farmer in Babylon province, Al-Dabla region, 17 km south of Al-Hillah city during autumn season 2017, to study the effect of two factors the first factor: was three varieties of potato tubers (Arizona, Agria, Riviera),class A which obtained from the yield of spring season at the same year which produced by the same farmer of the Elite order.The second factor: wasusing three extracts of seaweed plants (Phylgreenmira, Algazone, Ultra-kelp) at a concentration of (3 cm3.L-1) for all extracts in addition to the control treatment.The experiment was conducted in the field according to Split Plot Design with in Randomized Complete Block Design (R.C.B.D). Means were compared using the Duncan Multiplicity Range (DMRT) at probability level of 0.05. Results are summarized as follows: The plants of Arizona variety gave the highest values in plant height, number of aerial stems per plants, leaf area per plant, the percentage of dry matter ofwhole vegetative, number of tubers per plant, mean weight of tuber, plant yield and total yield of tubers (40.95 t.ha-1). Arizona and Riviera were superiorin dry matter and starchpercentage in tubers and specific gravity of tubers. Seaweed extract (Phylgreenmira) was significantly excelled in vegetative and quantitative traits by when gave the highest total yield of tubers (35.74 t.ha-1), while the three extracts were superior in the qualitative yield traits compared to the control treatment.The interaction between Arizona variety and Phylgreenmira seaweed extract was superior in all the studied traits which gave the highest total yield of tubers (47.89 t.ha-1).
