Testing cover crop species under three soil moisture conditions in a controlled greenhouse environment

Extreme climatic events, such as drought and heavy rainfall, are increasing with climate change. These events can threaten agroecosystems, including vineyards. Cover crops often grown in vineyards for various reasons be an effective strategy change adaptation. Understanding which cover crop species establish well under extreme conditions is important. We conducted a greenhouse experiment to investigate the responses of nine overwatered water-deficit conditions. Treatments included (1) soil condition, watered at 100% field capacity daily, (2) control, 60%–70% every other day, (3) water deficit, 15%–20% weekly 53 growing days. Results indicated that total dry weight all decreased (most significantly) However, pubescent wheatgrass red fescue did not exhibit any stress symptoms. Apart from alfalfa, established despite slight yellowing foliage crimson clover hairy vetch. Pearl millet yellow sweet had best establishment regardless Our results provide important information on selection withstand variability thrive linked scenario Canada.
