Management practice and soil properties affect plant productivity and root biomass in endophyte?symbiotic and endophyte?free meadow fescue grasses

Introduction Pesticides are increasingly used in intensely managed agro-environments, with an acknowledged impact on crop production, root establishment and plant resilience. At the same time management practices intensified goal to maximize productivity. Materials Methods In a greenhouse, we studied effects of three mowing regimes (uncut, cutting 5 or 15 cm) employed times during season shoot biomass chlorophyll content cool-season grass Festuca pratensis (meadow fescue) growing soil history glyphosate-based herbicide (GBH) use, corresponding control soil, sterilized soil. Half plants hosted systemic vertically transmitted fungal endophyte, Epichloë uncinata, which is known promote host growth. Results Endophyte symbiosis did not affect any tested parameters. Cutting cm decreased both cumulative biomass. Herbicide history, together intense (5 cm), caused decrease lowered content. Surprisingly, sterilization boosted concentrations less (15 noncutting when compared Root reduced uncut glyphosate use. Conclusion Our results indicate that GBH residues can diminish frequently cut. Decreased by goes reduction carbon allocation belowground, decreases grassland resilience climate warming, occurring droughts extreme weather events.
