Abstract: Sugarcane (Saccharum officinarum L.) is an important crop in India and its cultivation plays an important role in the country's economy. Rhizosphere microbiome plays a critical role in plant health, nutrient acquisition, and productivity. In this study, we investigated the rhizosphere microbiota of high- and low-yielding sugarcane fields using 16S rRNA gene (Ribosomal RNA gene) based high-throughput sequencing. The results revealed a diverse microbial community that present in high- and low-yield sugarcane, dominated by bacterial phyla such as Proteobacteria, Firmicutes_A, Bacteroidetes, Actinobacteriota, Patescibacteria, Firmicutes_D, Acidobacteriota, and Chloroflexota. High-yielding sugarcane in Shamli district was enriched with plant growth-promoting genera such as Azospirillum, Burkholderia, Mesorhizobium, Sphingomonas, Sphingobium and Rhizobium, whereas low-yielding sugarcane in Hapur district was dominated by Thiobacillus. This study highlights the importance of rhizosphere bacteria in sustainable sugarcane farming. To increase sugarcane yield, this study offers a foundation for developing microbial consortia of plant growth-promoting bacteria (PGPBs) that can be helpful in enhancing crop productivity.
