Response of Soybean (Glycine max L. Merrill) Plant Growth and Production to Liquid Organic Fertilizer from Vegetable Waste and Goat Manure

Abstract

Liquid organic fertilizer is a solution of the product decomposition of organic materials that come from plant residues, animal waste, and humans that contains more than one nutrient element.

This research was to determine the effect of giving Liquid Organic fertilizer (POC) of vegetable waste and goat manure on the growth and production of soybean (Glycine max (L) Merrill) in order to boost growth and production yields. This study used a factorial randomized block design (RBD) consisting of 2 factors and replicated 2 times. The first factor in giving POC of vegetable waste consists of S0 = 0 mL/L-solution/plot, S1 = 125 mL/L-solution/plot, S2 = 250 mL/L-solution/plot, and S3 = 375 mL/L-solution/plot. The second factor of giving goat manure consists of K0 = 0 kg/plot, K1 = 2 kg/plot, K2 = 3 kg/plot, and K3 = 4 kg/plot. The plot is an experimental plot measuring 1 m by 1 m. The results showed that the POC of vegetable waste was not significantly different at plant heights and ages at 2 and 3 weeks after planting, but had a very significant effect at ages 3, and 4 weeks after planting, on the number of pods per sample, number of pods per plot, and weight of pod production per plot, and had a significant effect on the weight of 100 seeds per plot. The application of goat manure was not significantly different at plant height ages 2 and 3, but had a significant effect at ages 3 and 4 weeks after planting, on the number of pods per sample, the number of pods per plot, and the weight of pod production per plot, and had a very significant effect on the weight of 100 seeds per plot.
