Study of the utilization of RIM (refresh microorganism) in sugarcane

Abstract

Sugarcane is used by its stems as the main raw material for sugar. In addition to improving soil structure, soil organic matter also supplies soil nutrients, especially Nitrogen, Phosphor and Sulfur, increases soil aggregate stability, increases groundwater holding capacity and increases soil recoverability. To overcome this problem, the use of RIM microorganism (refresh microorganism) technology in sugarcane fields needs to be done to reduce the use of chemical fertilizers which will ultimately lead to the realization of the application of organic farming systems in sugarcane cultivation. The purpose of this study was to study the effect of different dosage applications of RIM and various sources of organic matter on the growth and yield of sugarcane. This research consisted of two stages, namely in the greenhouse and in the field, namely (1) testing the growth of bud chip sugarcane seedlings using different growth media and microorganism technology (2) testing the effect of RIM applications and organic matter on the growth and yield of sugarcane. The use of RIM's Biological Agents by using Tricho derma, Sacharomyces, Bacillus, Rhizobium, Azotobacter and Pseudomonas bacteria was able to increase the growth of sugarcane buds. The combination of using RIM and manure can increase the number of leaves and the percentage of growing sugarcane.
