Abstract

As a high-value commodity, sugarcane harvesting areas in Indonesia have been declining year after year. Metagenomic studies on sugarcane plantation land are expected to provide an overview of land suitability for sustainable sugarcane production. This study investigated soil fungal communities in two sugarcane plantations, Bunga Mayang (BUMA) and Cinta Manis (CIMA), in Lampung and South Sumatra, respectively, using high-throughput ITS1 gene sequencing. Chemical and biological analyses were conducted on soils with depths of 0-20 cm and 20-      40 cm on plant cane (PC) and ratoon cane (RC) categories. The results showed that plantation land in South Sumatra (CIMA) had higher organic carbon and total nitrogen concentrations than in Lampung (BUMA). However, in several other parameters, such as P2O5, K2O, and microbial population, the BUMA farm has higher values with lower pH. Metagenomic analysis revealed the differences in microbial dominance between the plantation areas. Sugarcane fields in Lampung were dominated by the genus Protrudomyces, Coralloidiomyces, and Spizellomyces, while South Sumatra was dominated by the genus Lichtheimia, Phyctochytrium, and Spizellomyces. In the RC category, Lichtheimia corymbifera is the most dominant species in both the BUMA (RC-B) and CIMA (RC-C) plantations. However, in the PC category, BUMA (PC-B) is dominated by Protrudomyces lateralis, meanwhile CIMA (PC-C) is dominated by Phlyctochytrium californicum. The alpha diversity values of the two areas did not significantly different, with low Trichoderma populations. Thus, sugarcane fields in the two locations differ in microbial composition, which is thought to be influenced by different technical cultures and environmental conditions.
