Pemanfaatan Pupuk Organik Granular dari Limbah Destilasi Etanol Sorgum untuk Pembibitan Leda (Eucalyptus deglupta) pada Tanah Andosol, Latosol, dan Podzolik
MetadataShow full item record
Sorghum (Sorghum bicolor L Moenc) is a plant that can be used for food, feed, and energy (ethanol). There are two types of waste in ethanol production, liquid and solid waste (baggase). Liquid waste was produced from ethanol distillation process, rich in nutrients as fertilizer, but there is still limited information about its nutritional content, especially for producing forestry seedlings. There are two types of organic fertilizer those are liquid organic fertilizer (LOF) and granular organic fertilizer (GOF). This experiment examined the effect of the GOF of Sorghum liquid waste to leda seedling growth in different soil type of Andosol, Latosol, and Podzolik, and also to find the exact dose of GOF for leda seedling growth in each type of soil. Factorial in Completely Randomized Design was used in this experiment. The result showed, that application of GOF effected to almost all the growth parameters on three soil types. Best seedling quality index (SQI) of leda was found in the combination of Andosol and 20 granules of GOF with SQI 30 points, while the SQI value of both interaction was 30 points out of 30 points.
