| Abstract | ||
| Field study was conducted at AL-Twaitha Experimental Station/Baghdad,The agricultural Research, Ministry of Sciences and Technology during spring and fall seasons of 2011.Seed tuber produced from the hydroponic culture and the imported Riviera cultivar class Elite were cultivated in split – plot design with R.C.B.D which included the effect of chemical fertilization and spraying nutrient on growth and yield of potato tubers. Results showed that imported cultivars (C) was superior in plant emergence , plant height , leaf area and the dry weight of the vegetative parts (95.00 % , 50.77 cm , 89.83 Dcm2 and 56.10 g / plant respectively) for spring season while no significant difference for the studied characters in fall season. Fertilizer treatments significantly increased the averages of the vegetative characters,F1F4(Nutrient solution+Agroleaf) treatment significantly increased the number of stem per plant and the dry weight of vegetative parts for both spring and fall seasons (3.99 stem / plant, 61.41 g/plant) and (3.50 stem/ lant, 53.31g/plant) respectively, where as treatment F1F3(Nutrient solution+Magnum ) was superior in plant height of 54.33 cm in spring season and treatment F1F2 of 47.92 in fall season. Treatment F1F4 significantly gave the highest average number of tubers, plant yield and the total yield (6.66 tuber/plant, 723.00 g, 32.78 ton/ ha.) and (6.91 tuber / plant , 580.00 g , 30.66 ton/ ha) for both seasons respectively. The same treatment F1F4 gave the highest tuber weight of 83.91 g in fall season.The interaction treatment CF1F4(imported seeds+ Nutrient solution+ Agroleaf ) significantly increased the plant yield and total yield in ton / ha. For both seasons up to (834.00 g,42.96 ton/ ha) and (592.00 g , 31.48 ton/ha) respectively. | ||
