The Effect of Liquid Organic Fertilizer from Plant Waste, Livestock Waste, and Fish Waste on Growth of Marigold; The 2nd International Conference on Bioenergy and Environmentally Sustainable

This study used a completely randomized design with six treatments consisting of four types of liquid organic fertilizer, NPK Mutiara fertilizer, and control (without fertilizer) which was repeated four times. The results showed that the treatment of liquid organic fertilizer had a significant (P < 0.05) to very significant (P < 0.01) effect on the growth and yield of marigold flower plants. The highest weight of marigold flowers per plant was found in the treatment of liquid organic fertilizer mixed with plant waste, livestock waste, and fish waste of 79.70 g, followed by treatment of liquid organic fertilizer of fish waste at 59.13 g, liquid organic fertilizer from livestock waste at 51.43 g, NPK Mutiara fertilizer of 34.78 g, plant waste of 28.17 g, and the lowest flower weight per plant was found in the control (without fertilizer) of 25.57 g per plant. The mixed liquid organic fertilizer treatment gave the best effect, which was able to increase the number of marigold flowers up to 246 %, flower diameter 114 %, flower fresh weight 137 %, and flower weight per plant up to 311. 69 % compared to the control.
