Abstract


Radish (Raphanus sativus L.) is a tuber vegetable plant with high nutritional value. However, radish productivity in Indonesia is still low due to decreasing soil fertility and dependence on chemical fertilizers. Efforts to increase yields can be done by improving the planting medium through the addition of organic materials and the use of Liquid Organic Fertilizers (LOF) such as ecoenzymes. This study aims to determine the effect of organic material composition and ecoenzyme concentration on the growth, yield, and quality of white radish plants. The study used a factorial Randomized Block Design (RBD) with two factors. The first factor is the composition of organic materials as a medium consisting of 4 levels: M0: control, M1: soil + goat manure 20 t/ha, M2: soil + goat manure 10 t/ha + azolla 10 t/ha, M3: soil + azolla 20 t/ha. While the second factor is the ecoenzyme concentration consisting of 3 levels: K0 = without ecoenzyme administration (control), K1 = ecoenzyme concentration 1 ml/liter of water, K2 = ecoenzyme concentration 2 ml/liter of water. The results showed that the soil + azolla treatment of 20 t/ha combined with various ecoenzyme concentrations gave the best results on tuber length. Separately, the soil + azolla treatment of 20 t/ha gave the best results on the number of leaves, leaf area, total fresh weight, tuber weight, tuber diameter, tuber length, and chlorophyll content. While the ecoenzyme concentration of 1 ml/liter gave the best results on vegetative growth, and the ecoenzyme concentration of 2 ml/liter increased the content of vitamin C and chlorophyll.
