Growth and Quality of Strawberry (Fragaria ananassa Dutch. cvs. ‘Kuemsil’) Affected by Nutrient Solution Supplying Control System Using Drainage Rate in Hydroponic Systems

Although hydroponic techniques enable intensive and effective crop management, controlling the watering for each type growth stage is challenging using commonly used timed system. Therefore, excessive insufficient occurs frequently. Hydroponic technology that considers drainage rate can minimize amount of drainage, thereby reducing environmental pollution fertilizer consumption. This study compared methods in a strawberry system determined optimal rate. As increased, water supplied increased. A significantly negative correlation was found between total nitrogen content. Drainage electrical conductivity (EC) level highest 10% group. In 20% treatment, leaf length width increased to four applications timer-supplying method. The yield fruits weighing more than 27 g treatment. treatment most appropriate. We propose it possible reduce unnecessary consumption increase productivity by supply precise management strawberries.
