Abstract

Onion (Allium cepa) is a globally important horticultural crop. Its cultivation faces increasing challenges from climate change, soil degradation, and rising disease pressure. Modern agriculture must address these issues while advancing towards sustainable production in line with the United Nations Sustainable Development Goals. Plant-associated beneficial microorganisms, including beneficial bacteria and fungi, have emerged as promising tools for enhancing crop growth, nutrient uptake, disease resistance, and stress tolerance. This study presents a comprehensive scientific review of the current knowledge on the role of beneficial microorganisms in onion cultivation. In
addition, an interview-based survey was conducted with Swedish onion farmers to assess their awareness, perceptions, and adoption of microbiome-based agricultural practices. The findings reveal that while scientific evidence supports the benefits of microbiome management in onions, practical application in Sweden remains limited by knowledge gaps and resource constraints. The study highlights strengthening farmer education and integrating microbiome strategies can support more sustainable and resilient onion production, aligning with the United Nations Sustainable Development Goals.
