“…Although only one red clover cultivar was used in this experiment, others have found low persistency of red clover cultivars to be associated with the inability of red clover to replace tiller death and senescence (Marshall, Collins, Vale, & Lowe, 2017), since red clover plants grow from apical meristems and the generation of new plants is achieved by seed with low yield potential (Clifford & Scott, 1989) that is prone to fungal diseases (Skipp & Christensen, 1990).

“…The red clover cultivar had greater DM yield than five of the eight lucerne cultivars in the first-year ley but lower DM yield than most of the lucerne cultivars in the second-year ley, indicating lower persistency of red clover Titus compared to lucerne.

Increased knowledge about perennial forage growth throughout the harvest season is essential to manage grasslands strategically in order to meet the requirements of livestock production (Elgersma & Søegaard, 2018). High and persistent yields are essential for economical herbage production systems, while high nutritive value of forages is required to improve animal performance. However, red clover has generally greater nutritive quality and dry-matter (DM) yield in the first-year ley compared to lucerne, but depending on the soil characteristics and weather conditions, red clover DM yield can sharply decrease over the subsequent years due to its low persistency compared to lucerne (Phelan et al., 2015). Therefore, there is a growing interest to include both red clover and lucerne in legume-grass mixtures to maintain the legume proportion of the mixture over years (Undersander et al., 2011).However, there is only limited information available on potential differences in yield and chemical composition of lucerne cultivars originating from various countries. Subsequently, it is highly relevant to investigate yield and nutritive value of a range of different lucerne cultivars and of a tetraploid European red clover cultivar, which has similar growth rate as lucerne.The objectives of this study were to a) compare yield and nutritive value of eight lucerne cultivars and one red clover cultivar over two years under less favourable growing conditions for lucerne and b) compare digestibility and crude protein quality of four lucerne cultivars and AbstractRed clover (Trifolium pratense) and lucerne (Medicago sativa) are among the most common legume species used for ruminant feeding systems. Besides the greater nutritive quality and first-year ley yield compared to lucerne, red clover decreases its yield over the years. However, under unfavourable soil conditions the persistency of lucerne can be compromised, not performing as expected. This study compared yield and chemical composition of eight lucerne cultivars and one tetraploid red clover cultivar, with similar growth capacity as lucerne, replicated over two years. In the second year, four lucerne cultivars and the red clover cultivar were analysed for crude protein (CP) fractions, dry matter and neutral detergent fibre (NDF) digestibility. A randomized block design was used with three field blocks per cultivar for the multiple comparisons within each year. There were differences in DM yield, concentrations of CP and NDF and CP fractions among the lucerne cultivars, but the differences were inconsistent between years and between growth cycles within year. The red clover cultivar had lower CP and NDF concentrations than a majority of the lucerne cultivars, and greater in vitro organic matter digestibility compared to all of the lucerne cultivars.Also, the red clover cultivar had greater rumen undegradable-to-degradable CP ratio but confirmed its lower yield persistency compared to the lucerne cultivars.

“…Red clover (RC) is a forage legume cultivated in the temperate world, noted for its high-protein feed (Marshall et al, 2017) and high rate of biological nitrogen fi xation (BNF) (Dhamala et al, 2017). This review will focus on the use of RC in soil fertility-building, the contribution it can make to sustainable intensifi cation and the reduction of agriculture's environmental impact.…”

Red clover cultivation made signifi cant contributions to soil fertility prior to the introduction of mineral nitrogen fertilizers. Its modern usage lies primarily in forage production, but reintegration into arable systems can enhance sustainability and preserve environmental integrity. Here we review red clovers nitrogen (N) contribution to subsequent crops, its capacity to fi x N, and how this N is transferred to subsequent crops. The senescence of the root system following cultivation also contributes to soil organic matter, providing a suite of ecosystem services which are also reviewed. Potential contributions to allelopathic weed control and how this may be utilized to improve weed control is also discussed. Red clover varieties are diverse and can be split into categories of early/late fl owering, erect/prostrate and diploid/tetraploid. This use of this diversity to diff erent ends and purposes in fertility-building and the role of plant breeding in optimizing use of genetic resources is reviewed. Management strategies are also diverse; red clover can be grown in monoculture or with companion grasses, it can be harvested for forage or green manured (which can include or omit herbicides) and the consequence of this for soil fertility is discussed. High protein forage production is also a key benefi t of red clover cultivation and the economic incentive this may provide to farmers is also reviewed.

“…As shown in Figure 6, there were nine major components (1)(2)(3)(4)(5)(6)(7)(8)(9) in the T. pratense L. extract. After the use of methanol to denature the enzyme and dislodge the specifically bound compounds and the ultrasonication of the extract with COX-2-coated magnetic nanoparticles, two main peaks, 4 and 6, completely disappeared in the supernatant, while the peak area of 8 and 9 were significantly reduced.…”

Nonsteroidal anti‐inflammatory drugs reportedly reduce the risk of developing cancer. One mechanism by which they reduce carcinogenesis involves the inhibition of the activity of cyclooxygenase‐2, an enzyme that is overexpressed in various cancer tissues. Its overexpression increases cell proliferation and inhibits apoptosis. However, selected cyclooxygenase‐2 inhibitors can also act through cyclooxygenase‐independent mechanisms. In this study, using ultrafiltration, enzyme‐immobilized magnetic beads, high‐performance liquid chromatography, and electrospray‐ionization mass spectrometry, several isoflavonoids in Trifolium pratense L. extracts were screened and identified. Semi‐preparative high‐performance liquid chromatography and high‐speed counter‐current chromatography were then applied to separate the active constituents. Using these methods, seven major compounds were identified in Trifolium pratense L. As cyclooxygenase‐2 inhibitors: rothindin, ononin, daidzein, trifoside, pseudobaptigenin, formononetin, and biochanin A, which were then isolated with >92% purity. This is the first report of the presence of potent cyclooxygenase‐2 inhibitors in Trifolium pratense L. extracts. The results of this study demonstrate that the systematic isolation of bioactive components from Trifolium pratense L., by using ultrafiltration, enzyme‐immobilized magnetic beads, semi‐preparative high‐performance liquid chromatography, and high‐speed counter‐current chromatography, represents a feasible and efficient technique that could be extended for the identification and isolation of other enzyme inhibitors.
