White clover inclusion in intensive dairy production systems
Incorporating white clover into intensive dairy production systems has the potential to increase their sustainability through increased milk output and reduced nitrogen (N) input. To support intensive stocking rates (<2.75 cows/ha) some inorganic N will still be required to support herbage …

Response of Leaf Protein to Ozone in Two White Clover Clones
A white clover ( Trifolium repens ) system, based on one ozone-sensitive (NC-S) and one ozone-resistant (NC-R) clone, has been developed as an indicator to estimate the effects of tropospheric ozone on plant biomass production. A reduction in the vegetative biomass ratio (NC-S/NC-R) of the clones …

ENHANCED SOIL STRUCTURING BENEATH WHITE CLOVER AND ITS IMPACT ON NUTRIENT TRANSPORT
… that soil structural differentiation under white clover is phenomenally rapid and enhanced when compared with ryegrass. White clover is one of the most nutritious and widely distributed forage legumes. Its use is advocated in sustainable systems of livestock production because of its ability …

Caucasian clover establishment in the high country and grazing responses in ryegrass/white clover lowland pasture
… early root and rhizome development of Caucasian clover (Trifolium ambiguum) was sown in early October 1992, on a low-fertility, depleted, short tussock grassland site at Mesopotamia Station, South Canterbury. Three sowing techniques, broadcasting, sod seeding and strip seeding, each with two …

Molecular and Physiological Aspects of Arbuscular Mycorrhizal Symbiosis with near-Isogenic White Clover: A Gene Expression Study
White clover (<i>Trifolium repens</i> L.) is an important component of low input pasture systems and can form effective associations with both nitrogen-fixing Rhizobium and phosphate-scavenging arbuscular mycorrhizal fungi (AMF). Understanding the genetic control of plant-AM interactions will allow …

Protein from pasture
Ryegrass, white clover, ryegra.ss/whi te clover and lucerne herbages were used in an industrial pilot-scale study of the effects of regrowth period and season on protein extraction, separation and recovery. Herbage was harvested, adjusted to 10% tlry matter, pulped and (belt) pressed. Protein in …

Evaluation of florpyrauxifen-benzyl for use in pastures and hayfields
… species such as forage legumes, including white clover. Use of herbicides can lead to severe injury and often complete elimination of white clover, making it difficult for producers to maintain legumes in mixed grass-legume swards while controlling weeds. It is often desirable to have …

Effect of Lolium perenne L. ploidy, Trifolium repens L. inclusion and cow breed on the productivity and profitability of pasture-based, spring-milk systems
… (Lolium perenne L.; PRG) sown with and without white clover (Trifolium repens L.). Four grazing treatments were compared for this study; tetraploid PRGonly swards, diploid PRG-only swards, tetraploid PRG with white clover swards and diploid PRG with white clover swards. Three cow genotypes were …

Effects of nitrogen and cutting management on root growth and productivity of a Kentucky bluegrass (Poa pratensis L.) and white clover (Trifolium repens L.) pasture
… soil nitrate (NO3-) in a Kentucky bluegrass and white clover pasture were examined. Nitrogen was applied annually in two equally split applications at rates of 0, 80 or 160 kg N ha -1. After reaching 12.7 cm, plants were cut to 2.5, 5.1 or 7.6 cm. Herbage was analyzed for yield, crude protein …

Evaluation of perennial ryegrass cultivars for dairy production under different pasture management
… perennial ryegrass cultivars with and without white clover (Trifolium repens L.) (experiments 1, 2, 3 and 4) and defoliating at different times of day (experiments 2 and 5) during pasture regrowth (experiment 2). In experiment 1, morphology and nutritive value of eight perennial ryegrass …

Digestibility, intake and selectivity of three mixed-forage pastures by cattle
… pastures, alfalfa-orchardgrass, bluegrass-white clover, and fescue-red clover. Three steers, three heifers and one esophageally cannulated steer were randomly assigned to each pasture treatment. Chemical composition, digestibility, voluntary intake, and selectivity of the forages were …

Influence of endophyte infection of tall fescue with and without white clover on performance, intake, and bite size in steers during the grazing season and subsequent performance in the feedlot
… endophyte infected tall fescue, with and without white clover (Trifolium repens L.), were studied with yearling steers. At each location, two replicates were used with a stocking rate of .3 ha/steer (116 steers/yr). At the end of grazing, all animals were finished on a high corn silage diet and …

Autumn performance of rhizomatous clovers after a summer drought, under different grazing treatments
Caucasian clover (Trifolium ambiguum; cv. Monaro and Alpine), zigzag clover (Trifolium medium; seed lines, Kentucky and Porters Pass) and white clover (Trifolium repens), were evaluated in a sheep grazing trial on a lowland medium fertility soil (Templeton silt loam) at Lincoln University, …

Isolation and detection of bean yellow mosaic, clover yellow vein and peanut stunt viruses from Trifolium L. species
Trifolium L. (clover) are annual or perennial species established in pasturelands to improve forage productivity and quality. In the southeastern United States, Trifolium repens L. (white clover) and Trifolium pratense L. (red clover) are important species, susceptible to virus infection. …

Functional and community investigation of nodule endophytes for the selection of phosphate solubilizing rhizobial inoculants for clover : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
… Zealand, most pastures contain Trifolium repens (white clover) and T. subterraneum (subterranean clover) grown in mixture with forage grasses. Clovers are nodulated with Rhizobium spp. to fix nitrogen. These bacteria can also release organic acids, phytases and phosphatases to make P soluble and …
