The Influence Of Cow Urine Fertilizer, Leaf Bokashi, And AB Mix For The Growth Of Water Spinach Plant (Ipomoea Reptans Var.Poir) With The DFT (Deep Flow Technique) Hydroponic System At Adventist University Of Indonesia
Keywords:Cow urine, Hydroponics, Kale (Ipomoea reptants var.poir)
Urine cow is livestock waste that can be used as liquid fertilizer. Urine has a high N and K
content and there is enough P content for plant development. Besides being able to work
quickly, urine turns out to contain certain hormones that can stimulate plant development.
Urine in cattle consists of 92% water, nitrogen 1.00%, 0.2% phosphorus, and 0.35%
potassium. Water spinach is a vegetable commodity that is liked by many people, its
nutritional content is high, and its cultivation is very simple and easy. The nutritional content
of kale is quite high, especially vitamin A, vitamin C, iron, calcium, potassium, and
phosphorus. Hydroponic system cultivation can be done in a backyard. The purpose of this
study was to determine growth by using leaf Bokashi, cow urine, and AB Mix (control). One-
way ANOVA and Duncan data analysis with a significant level of α = 0.05. The results
obtained showed that the urine urine nutrition affected the growth of plant height, leaf
number, leaf width, and root length, giving significance to the testing of descriptive analysis.
