The effectivity testing bio-organic fertilizer toward the plant’s growth and productions of water spinach (Ipomoea reptans Poir)

Farmers tend to use chemical fertilizer to boost their water spinach production. Consumers’ demand for high quality and the chemical-free product should be considered in using less chemical fertilizer. A possible solution is using a safe and eco-friendly bio-organic fertilizer. In general, this study purposes of supporting food security, which can provide food with the best quality and safe to consume by people and not harm the environment. Moreover, this study aims to acknowledge the effectivity of bio-organic fertilizers (Petrobio, Marolis, and Fertismart) toward the plant’s growth and production of water spinach. This study used the factorial plan in RAL, which consists of 2 factors. First, the bio-organic fertilizer that has 3 stages: Petrobio, Marolis, and Fertismar. Second, the use of NPK fertilizer: without NPK, 50% used, and 25% used for each trial should pass three times examination. The result shows that using bio-organic fertilizer can affect the plant’s growth and productions, with the evidence of the plant’s height, number of leaves, and plant’s net-masses. Bio-organic could decrease the application of chemical fertilizer; by contrast, it can’t substitute NPK to boost the water spinach production. The best result was from the fertilized plant using Marolis alongside with NPK.
