The Role of Leri Water and Planting Media on The Production of Vitamin C and Calcium (Ca) in Microgreen Sunflower (Helianthus annuus L.)
Abstract
The spread of viral outbreaks is currently rife, resulting in people lacking the immune system. It is important for people to eat healthy foods in the form of vegetables that can be planted in their yards, given the limited agricultural land. Microgreens are vegetables that are rich in vitamins, and can be cultivated in the yard of the house. Factors that need to be considered, one of which is the provision of nutrition and the use of growing media that can support microgreen yields. There are many types of plants that are cultivated into microgreens, one of which is sunflower. The provision of nutrients such as rice water and the use of planting media such as cocopeat, husk charcoal, and tissue paper are considered to increase microgreen yields. This study aims to determine the effect of rice water concentration and the use of growing media on the yield of microgreen sunflower (Helianthus annuus L.). This research was conducted in September-December 2021 in Simo Mulyo Baru, Surabaya City, East Java. The research method used a Completely Randomized Design (CRD) system consisting of 2 factors with 3 replications. The first factor is the concentration of rice water which consists of 4 levels of treatment and the second factor is the use of planting media which consists of 3 levels of treatment. The results showed that the concentration of 20% rice water and the use of cocopeat growing media could increase the average yield of microgreens.
