We investigated the legacy effects of a previous ley’s legume proportion on the performance of a following grass crop in a rotation. In April 2015, a pure Lolium multiflorum L. crop was sown after the removal of legume containing swards (0–100% legumes), and was harvested four times over the following one-year period (3 times in 2015 and once the following April 2016). Labeled 15N fertilizer (50 kg N ha−1) was applied during the 2nd and 3rd re-growth periods to determine N fluxes. Across the one...

Abstract Grass-legume mixtures characterized by high productivity, efficient nitrogen (N) use and strong weed suppression were proposed to increase sustainability of grassland production. Adding competitive forbs to grass-clover mixtures can be expected to further enhance the high productivity of grass-clover mixtures. This study investigates whether and to what extent adding forbs to a grass-clover mixture results in yield gains, and estimates the contributions of forb species (identity effect)...

Climate models predict increased frequency and severity of drought events. At an Irish and Swiss site, experimental summer droughts were applied over two successive years to grassland plots sown with one, two or four grassland species with contrasting functional traits. Mean yield and plot-to-plot variance of yield were measured across harvests during drought and after a subsequent post-drought recovery period. At both sites, there was a positive relationship between species richness and yield. ...

Abstract Climate change is predicted to result in more severe weather events, including drought, which will affect forage production in agricultural grasslands. We evaluated the effects of an experimentally imposed drought on yields of monocultures and mixtures of intensively managed grassland communities comprising four species with contrasting functional traits ( Lolium perenne L., Cichorium intybus L., Trifolium repens L., Trifolium pratense L.). Complete exclusion of precipitation was implem...

1. Grassland diversity can support sustainable intensification of grassland production through increased yields, reduced inputs and limited weed invasion. We report the effects of diversity on weed suppression from 3 years of a 31-site continental-scale field experiment. 2. At each site, 15 grassland communities comprising four monocultures and 11 four-species mixtures based on a wide range of species’ proportions were sown at two densities and managed by cutting. Forage species were selected ac...

Aims We investigated whether drought-induced impairment of grassland species can be explained directly by plant water deficit or by water-driven limitation of nitrogen (N) and/or carbohydrate sources.

Summary Increased species diversity promotes ecosystem function; however, the dynamics of multi-species grassland systems over time and their role in sustaining higher yields generated by increased diversity are still poorly understood. We investigated the development of species’ relative abundances in grassland mixtures over 3 years to identify drivers of diversity change and their links to yield diversity effects. A continental-scale field experiment was conducted at 31 sites using 11 differen...

Abstract Weeds in intensively managed grassland can result in substantial losses of forage yield and quality. We studied whether weeds could be suppressed sustainably by use of functionally diverse grassland mixtures with high resource capture and biomass yield. To this aim, growth of planted phytometers and of spontaneously establishing, unsown species were evaluated. To represent weeds, seedlings of five model species were grown up as phytometer plants in stands of forage leys under two precip...

Forage species of intensively managed temperate grassland differ substantially in their drought responses. We investigated whether differences in resistance and resilience, based on biomass yield, are related to species nitrogen (N) acquisition and drought-induced N deficiency. A three-factorial field experiment was established with monocultures of four species (first factor) that differed in functional traits regarding N acquisition and rooting depth: Lolium perenne L. (shallow-rooted non-legum...
