RESPON PERTUMBUHAN DAN HASIL TANAMAN BAWANG MERAH (Allium ascalonicum L.) TERHADAP BERBAGAI KONSENTRASI ECO ENZIM

Abstract

This study aims to determine the effect and optimal concentration of eco-enzyme liquid organic fertilizer on the growth and yield of red onion plants. Eco-enzyme is an organic solution derived from the fermentation of kitchen waste, containing nutrients and beneficial microorganisms, thereby potentially serving as a liquid organic fertilizer. This study was conducted in Kampung Ni’u, Selama Village, Reok Sub-district, Manggarai District, East Nusa Tenggara. The study was conducted from October 2024 to December 2024. The research method used was a field experiment designed with a completely randomized block design, with one treatment factor: the concentration of liquid organic fertilizer eco-enzyme. The treatments used in this study were: E0: 0 mL/1 liter of water, E1: 5 mL/1 liter of water, E2: 7.5 mL/1 liter of water, E3: 15 mL/1 liter of water, E4: 22.5 mL/1 liter of water, and E5: 30 mL/1 liter of water. The treatment levels were repeated three times, resulting in 18 experimental units. Five plants were observed in each treatment. Each experimental unit contained 10 plants, resulting in a total of 6 × 3 × 10 = 180 plants and a total of 90 sample plants. The results of this study indicate that the application of various concentrations of eco-enzyme liquid organic fertilizer has a significant effect on all observed parameters, and the optimal concentration of eco-enzyme liquid organic fertilizer is found in treatment E5 at a concentration of 30 mL/liter of water.
