Effect of Organic Fertilizer Water Hyacinth on the Growth and Production Plant Taro (Colocasia esculenta L.)

Abstract

Taro as a source of food that is healthy and safe alternative potential, so that the role of fertilization and media technologies grow to be very important and expected organic fertilizer water hyacinth can increase the production of taro. The purpose of this study was to determine the effect of organic fertilizer dose of water hyacinth on the growth and yield of taro. This research method using Anova by F test and regression analysis. Variable observations were made on the vegetative phase (growth) and the generative phase (production). Variable observation of growth (plant height, number of leaves, leaf area) and production (weight of fresh taro) taro plants. The results showed that; 1) organic fertilizer water hyacinths very significant effect on the variable observation (plant height, number of leaves, leaf area) at the age of 30, 60, 90 days after planting, and 2) the average weight of fresh taro The resulting dose of organic fertilizer water hyacinth 20 tons/ha, which amounted to 2.77 kg but not significantly different with treatment dose of organic fertilizer water hyacinth 15 tonnes / ha, which amounted to 2.69 kg.
