The effect of N, P and K organic substances enhancers on fruit waste liquid organic fertilizer on tomato plants

Abstract

The manufacturing of liquid organic fertilizer (LOF) based on fruit waste can reduce the amount of waste. The research aims to determine that: 1) Tomato plants were affected by the application of some concentrations of fruit waste LOF that was not and given organic substances enhancers N, P, and K and 2) There was the best concentration of fruit waste LOF that was not and given organic substances enhancers N, P, and K on tomato plants. The research was designed in a group randomized design (GRD), with seven treatments tried, namely 0% (not given fruit waste LOF); concentrations of 30, 35, and 40% from fruit waste LOF that was not given organic substances enhancers N, P, and K; and concentration of 30, 35, and 40% from fruit waste LOF that was given organic substances enhancers N, P, and K. The observation parameters were plant height, plant stem diameter, amount of productive branches each pant, amount of tomatoes each plant, diameter of tomato fruit, and tomato fruit weight of each plant. The results of the research showed that 1) Fruit waste LOF that was given organic substances enhancers N, P, and K was a better effect than that was not given organic substances enhancers N, P, and K; and 2). Fruit waste LOF that was given organic substances enhancers N, P, and K at a concentration of 35% had the best effect on the average amount of tomatoes each plant (31.31) and tomato fruit weight each plant (2,535.25 g).
