Experiments were conducted to investigate the optimum concentration of nutrient solution in hydroponics for strawberry 'Ssanta' bred at Gyongsangbuk-do Agricultural Research & Extension Services.Nutrient solutions for strawberry, which made by Yamazaki, were supplied EC (Electrical Conductivity) 0.6,0.8, 1.2, and 1.8 dS · m1 after planting on cocopeat medium during experiment period. Growth of shoot of strawberries did not show statistical differences among treatments. Fruit length showed the longest in EC 0.8dS · m1 in all clusters. In the second flower cluster, fruit length showed longer in EC 0.8 and 1.2 dS · m1than EC 0.6 and 1.8 dS · m1. In the third flower cluster, it showed the longest in EC 0.8 and 1.2 dS · m1,followed by 0.6 and 1.8 dS · m1. The longest was in EC 0.8 dS · m1 and the shortest in EC 1.8 dS · m1 in the fourth flower cluster. Fruit diameter did not show significant differences among treatments, but longest in EC 0.8 and 1.2 dS · m1 in all clusters. The heaviest mean fruit weight appeared in EC 0.8 dS · m1 in all flower clusters. And heavier in EC 1.2 dS · m1 in the second and third clusters. Also the weight was significantly light in plants grown in EC 0.6 and 1.8 dS · m1 in the second and third cluster. Soluble solids of fruit was the highest in EC 0.6 dS · m1 in all clusters. As the results, we came to the conclusion that the optimum EC for strawberry 'Ssanta' was EC 0.8~1.2 dS · m1 in this experiment.
