| 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 grassclover 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) and interactions with the grass-clover mixture (diversity effect) to these gains. It further examines the effectiveness of weed suppression in forb-containing grass-clover mixtures. Fifteen pure and mixed stands, all comprising the grass Lolium perenne L. and the legume... |

| Anaerobic co-digestion of agricultural by-products or wastes with complementarity characteristics is commonly used to enhance methane yield. This study firstly explores the possibility of co-digesting grass and forb species (white clover, chicory and plantain) differing in nutrient composition in enhancing methane yield. This was examined with two inocula (a cattle manure-based inoculum and a grass-based inoculum) in a batch assay. Results showed that co-digesting grass and forbs synergistically enhanced methane yield potential on average by 31 L kg−1 volatile solids (+11%) and reduced lag phase time by 0.8 day in the grass-based inoculum, but not in the cattle manure-based inoculum. Mixtures containing plantain showed more consistent synergistic effect... |

| Adding certain forbs such as chicory (Cichorium intybus L.), caraway (Carum carvi L.) or plantain (Plantago lanceolata L.) to grass-clover mixtures can further enhance or largely maintain the high productivity of grass-clover mixtures (Cong et al., 2018). This study aimed to screen varieties of three competitive forbs - chicory, caraway and plantain with high yield and quality performance, and to examine whether these varieties perform well when grown with traditional grass-clover mixtures. |

| Perennial ryegrass-clover mixtures are widely used in intensively managed grasslands due to their high biomass production. Recent studies have shown that inclusion of competitive forbs such as plantain enhanced above-and below-ground biomass of ryegrass-red clover mixtures (Cong et al., 2016), while inclusion of forbs such as caraway in the grass-clover mixture largely maintained the herbage yield. Meanwhile, inclusion of forbs increases plant litter diversity, which could change root quality of the plant community. Hence, changes in quantity and quality of root litter in forb-containing grass-clover mixtures may potentially affect soil microbial community structure, biomass and associated ecosystem functions, but it is yet to be elucidated. We... |

| The response of above- and below-ground biomass to soil nutrient availability is crucial for estimating belowground carbon input and predicting changes in soil carbon storage. However, the response is far from clear at plant community level, especially for grassland systems. Using a long-term field experiment initiated 123 years ago with varying soil nutrient levels (deficient, sub-optimal, optimal and over-optimal) established by use of two nutrient sources (animal manure or mineral fertiliser), we examined the effects of soil nutrient level and source on herbage yield and composition, root biomass and root-to-shoot (R/S) ratio of an unfertilised multispecies grass-legume ley. Increased nutrient levels enhanced herbage yield, but did not affect root... |
