Effects of Reduced Watering Regimes on Hops Growth and Rhizospheric Microbial Communities

Reduced watering regimes differentially affected growth phenotypes of Humulus lupulus across five cultivars, while rhizosphere microbial associations showed more consistent cultivar-linked patterns.

• Why it matters: Climate-driven heat and reduced rainfall can reshape root-associated microbial communities, potentially influencing crop health beyond yield outcomes.
• What they did: In a multi-month drought tolerance garden experiment, the team combined phenotypic measurements with rhizosphere metabarcoding from Humulus lupulus cultivars Cascade, Centennial, Chinook, Comet, and CTZ.
• The result: Phenotypic analyses indicated cultivar-specific sensitivity to reduced watering, and microbial community data revealed consistent associations between rhizosphere taxa and cultivar type, informing drought-tolerance mechanisms.
