Utilization of Liquid Organic Fertilizer of Pineapple Waste to Improving Growth of Sweet Corn Plant in Red Yellow Podsolic Soil

Abstract

<em>This study aims to determine the effect of pineapple waste liquid organic fertilizer on the growth and yield of sweet corn in Red Yellow Podsolic soil and to obtain a dose of pineapple waste liquid organic fertilizer that can produce the highest growth and yield of sweet corn in Red Yellow Podsolic soil. This study used a completely randomized design (CRD), with 5 treatments repeated 5 times and 3 plant samples. The treatment given was in the form of a dose of liquid organic fertilizer with a dose of: P0 = 0 ml/l water, P1 = 25 ml/l water, P2 = 50 ml/l water, P3 = 75 ml/l water, P4 = 100 ml/l water. The parameters observed in this study were plant height, leaf area, root volume, soil pH, C-Organic content, N, C/N ratio and soil bulk weight. The data obtained were analyzed by fingerprint analysis of variance at the 5% level and then further tested with 5% HSD. Based on the results of the study, the dosage level of liquid organic fertilizer of pineapple waste had a significant effect on the variables of root volume and soil pH. However, it had no significant effect on the variables of plant height, leaf area, organic %C content, %N soil content, C/N ratio, and bulk density of Ultisol soil. The treatment level of liquid organic fertilizer from pineapple plant waste 50 ml/l gave the best results on the variable soil pH, and the dose of liquid organic fertilizer of pineapple plant waste 75 ml/l was the treatment that gave the best results on the variable root volume.</em>
