Preliminary Study On Field Application Of Human Urine Fertilizer On Cultivation of Green Amaranth In Bajeng Distric, Gowa, South Sulawesi

Abstract

Abstract: A field study was conducted in District Bajeng, Gowa regency, South Sulawesi to evaluate the efficay of human urine as fertilizer on green amaranth (Amaranthus sp.).  Amaranth planted on two seedbeds for fertilize application and the other two seedbeds for unfertilized amaranth planting. Fertilizer made of fresh human urine that were collected from farmers around the cultivation area, then diluted with water to obtain a concentration of 25%. Using an electric sprayer, fertilizer was watered directly to the soil, once in four days. Its efficacy was observed based on growth rate and yield performance including plant height, number of leaves, leaf width and biomass yield. The results indecated that all the fifth parameters are significantly better in urin-fertilized amaranth compared to unfertilized one. In conclusion, human urine may be effective as alternatif fertilizer for growing Amaranthus sp in field scale.
