Abstract

This study was conducted with the aim of finding a suitable hydroponic formula for kale (Brassica oleracea L. var. acephala) based on analyzing the growth and quality parameters of kale plants. To do this objective, kale plants were grown in 4 experimental formulas with a combination of 2 models of dynamic and static hydroponics and 2 nutrient solutions including Grow Master and BKFast. The results showed that kale plants grew and had the best quality when grown on a dynamic hydroponic system using the Grow Master solution. In detail, at the time of 70 days, the plant reached fresh weight of 52.55 g, with a height of 28.19 cm, an average number of leaves of 13.9, a vitamin C content of 125.17 mg/100g, a reduced sugar content of 6.9 mg/g. The formulas used the static hydroponic system, the plants had a slow growth rate with an average fresh weight of 1/5-1/6 times the fresh weight of the formula using the dynamic hydroponic system. The results of the study on nitrate content showed that kale plants grown in dynamic hydroponic systems had higher nitrate levels than plants grown in static hydroponic systems, ranging from 1342.65 - 1423.15 mg/kg. However, this nitrate results is still within the allowable limit for nitrate content in vegetables.
