Variasi Media Tanam dan Penambahan Ekstrak Taoge Terhadap Pertumbuhan Microgreen Lobak Merah (Raphanus Sativus L.)

Abstract

Microgreen are vegetables that can be harvested at a young age, approximaly at 7 to 14 days after sowing. The growth of microgreen is highly dependent on the planting media. The research on the Variation of Planting Media and the Addition of Bean Sprout Extract on the Growth of Red Radish Microgreen (Raphanus Sativus L.) had been carried out from December 2022 to January 2023 at the Laboratory of Plant Physiology and Tissue Culture, Faculty of Mathematics and Natural Sciences, University of North Sumatra. This study aimed to obtain the best combination of planting media and bean sprout extract concentrations for the growth of red radish (Raphanus sativus L.) microgreen. This study used a two-factor factorial Completely Randomized Design (CRD) with four media levels (cocopeat, husk charcoal, vermiculite, rockwool) and four levels of bean sprout extract (0 ml/L, 20 ml/L, 25 ml/L, 30 ml/L). The treatment of bean sprout extract was carried out twice a week as much as 50 ml. The results showed that the combination of bean sprout extract and planting media had a significant effect on the plant height, the wet weight, the root volume, the dry weight, the anthocyanin content and the crude fiber content. Sprout extract 25 ml/L with a combination of cocopeat planting media (E2M1) showed the highest value for all variables, such as plant height of 13.22 cm, wet weight of 48.87 g, root volume of 0.60 ml, dry weight of 5.61 g, content anthocyanins of 12.44 mg/L and the crude fiber content of 13.33%.
