Synergistic Effects of Photosynthetic Bacteria and Endophytes: A Novel Approach to Enhance Cayenne Pepper Productivity

Cayenne peppers (Capsicum frutescens) are a valuable commodity contributing significantly to the economy of Sleman Regency. Despite their substantial economic potential, cayenne pepper farming practices in Sleman often lack integration of sustainable and eco-friendly agricultural principles. This research aims to investigate the potential of utilizing photosynthetic bacteria and endophytic bacteria to enhance the growth and yield of cayenne peppers in Sleman Regency. The study was conducted in Gondang Lutung Hamlet, Donoharjo Village, Ngaglik District, Sleman. A randomized complete block design (RCBD) was employed with a single factor: beneficial bacteria type, including P1 (PSB + Endophyte), P2 (PSB), P3 (Endophyte), and P4 (Control). The findings revealed that the combination of photosynthetic bacteria and endophytic bacteria had varying effects on cayenne pepper growth. The combination treatment significantly enhanced plant height, chlorophyll content, flower number, fruit number per plant, fresh fruit weight, production, productivity, and resistance to C. capsici, C. gloeosporoides, and R. solanacearum. Single PSB application improved plant growth attributes, while Endophyte application demonstrated potential for enhancing cayenne pepper resistance to pathogens. The study demonstrates the potential of utilizing beneficial bacteria, particularly the combination of PSB and Endophyte, to enhance cayenne pepper growth, yield, and disease resistance. This research provides valuable insights for promoting sustainable and eco-friendly cayenne pepper farming practices.
