The influence of planting media and the concentration of tofu liquid fertilizer on the growth of kale land (ipomoea reptans poir) hydroponically

Kale land (Ipomoea reptana Poir) is one type of vegetable crop that is short-lived, has economic value, and also has a high nutritional content, namely vitamins A, B, C, protein, calcium, phosphorus, sitosterol, and mineral materials, especially iron that is useful for the growth of the body and health. Hydroponics is an alternative technology in the cultivation by using media other than soil and nutrient substrate. One alternative nutrient that can be applied, namely liquid fertilizer derived from the fermentation of waste from the manufacturing process. The purpose of this study is to investigate the influence of planting medium and the concentration of waste liquid manure out of the land kale growing hydroponically. The research was conducted in field trials in Suco Manleuana (Dili) began on 29 April 2018 until May 30, 2018. This study is a field experiment with the design used was a randomized block design pattern group with 2 factors. The first factor is the media's treatment plant consists of three types of growing media: M1: rice husk charcoal, M2: Sand rivers, and M3: Sand river + rice husk. The second factor is the provision of waste liquid fertilizer know which consists of four levels: P 0: Provision of waste liquid manure out of 0%, P1: Provision of waste liquid manure out of 10%, P 2: Provision of waste liquid manure out of 20%, P 3: Provision of waste liquid manure out 30%, and P 4: Provision of waste liquid manure out of 40%. Variables to be observed consist of plant height (observations on the first week to the fourth week), the number of leaves (observations on the first week to the fourth week), and the fresh weight of plant kale land (observations on the fourth week). The data obtained will be analyzed for variance and if necessary it will proceed with Duncans Multiple Range Test (DMRT) at the 5% significance level. Based on the results of further tests using Duncan's Multiple Range Test (DMRT) showed significant differences among treatments. Treatment shows the growth and yield of kale best land indicated in the treatment M1P3 (rice husk growing media and the concentration of waste liquid manure out of 30%) with a mean value of 10.83 the number of leaves, plant height 33.85 cm, and a wet weight of 14.33 grams.
