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

Abstract

Urine cow is livestock waste that can be used as liquid fertilizer. Urine has a high N and K and there is enough P content for plant development. Besides being able to work quickly, urine turns out of contain certain hormones that can stimulate plant development. Urine in catle consist 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 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 result obtained showed that the urine nutrition affected the growth of plant height, leaf number, leaf width, and root length, giving significant to the testing of descriptive analysis.
