Effects of nitrogen fertilizer and red clover (Trifolium pratense L.) component on productivity of grass-legume mixed swards
The effects of two levels of red clover (low and high) and three levels of N fertilizer (0, 28, 56 N kg ha-1) on herbage accumulation and quality of grass-legume mixed swards were studied. Total herbage accumulation of the mixtures with high legume percentage was significantly higher than those …

Egyptian Broomrape (Orobanche aegyptiaca Pers.) and Small Broomrape (Orobanche minor Sm.) Parasitism of Red Clover (Trifolium pratense L.) in Vitro
… growth. Parasitism as such leads to yield reductions, and in case of heavy infestations, complete crop failure. Among other plants parasitized by broomrapes are several legumes, some of which are also the world's most economically important crops. As part of their unique biology, legumes …

Non-uniform stands of red clover (Trifolium pratense L.) underseeded to winter wheat (Tritcum aestivum L.): A survey study to identify causes
Red clover (Trifolium pratense L.) use as an underseeded cover crop to winter wheat (Triticum aestivum L.) has declined in recent years as producers have been experiencing difficulties in maintaining uniform stands. The purpose of this study was to confirm if spatially variable emergence densities, …

GROWTH, NODULATION AND NITROGEN FIXATION OF ALFALFA (MEDICAGO SATIVA L) AND RED CLOVER (TRIFOLIUM PRATENSE L) AS INFLUENCED BY SOIL ACIDITY AND LIMING
… nitrogen fixation, and yield of alfalfa and red clover.</p><p>In the greenhouse, from soil pH 5.0 to 5.6, nitrogen fixation was shown to be more correlated to Al saturation than pH or available P. Once Al saturation was reduced to less than 5 percent by liming, the application of P was more …

Nitrogen utilization in tall fescue (Festuca arundinacea Schreb.) pastures fertilized with nitrogen or grown with alfalfa (Medicago sativa L.) or red clover (Trifolium pratense L.)
… and animal performance and has been suggested to reduce the potential for environmental pollution. "Kentucky 3l" tall fescue fertilized with 160 kg N ha-1 yr-1 (split application) was compared to tall fescue grown with alfalfa or red clover in a 5-yr pasture experiment on a mixed Typic Hapludult. …

Effects of overseeded legume living mulches and tillage on weed suppression and broccoli yield
… (underseeding) of legume cover crops (red clover, Trifolium pratense L.; white clover, Trifolium repens L.; and hairy vetch, Vicia villosa Roth.) at transplanting on weed suppression and yield of ’Big Sur’ broccoli (Brassica oleracea var. italica Plenck). In both sites, weed suppression …

Isoflavonoid induction and nitrogen assimilation in AM colonized red clover
This study postulates that the symbiosis between red clover, Trifolium pratense L., and the arbuscular mycorrhizal (AM) fungus, Glomus intraradices Schenck & Smith, enhances secondary phenolic metabolism and nitrogen assimilation. To test this hypothesis, the four objectives set forth were to …

Yield and nutritional value of orchardgrass as influenced by nitrogen and sulphur fertilization and associated red clover
The effects of red clover (Trifolium pratense, L.), three levels of N (0, 224 and 448 kg•ha⁻1•yr⁻1, as a split application) and two levels of S (0 and 34 kg•ha⁻1•yr ) on the chemical composition and dry matter digestibility of an orchardgrass (Dactylis glomerata, L.) sward were studied. The …

Yield, Quality, and Botanical Composition of Autumn-Accumulated Grass-Legume Mixtures and Digestibility of Ensiled Autumn-Accumulated Orchardgrass and Alfalfa
… in late summer to extend the grazing season and reduce feeding costs. Three stockpiled grass-legume mixtures were evaluated for winter grazing. In addition, stockpiled forages were ensiled and evaluated as livestock feed. Four accumulation dates and seven harvest dates were randomized to small …

Legume Establishment in Native Warm-Season Grass Pastures
… in NWSG. Two forage legumes, 'Alice' white clover (Trifolium repens L.) and 'Freedom HR' red clover (Trifolium pratense L.), were interseeded into mixed 'Niagara' big bluestem (Andropogon gerardii Vitman), 'GA Ecotype' Indiangrass (Sorghastrum nutans Nash), and 'Camper' little bluestem …

Assessing chemical control options and their effects on lesser clover leaf weevil, red clover pollinators and evaluating red clover seeding rates for optimal seed production and N fixation in Saskatchewan, Canada
Red clover (Trifolium pratense L.) seed production in Saskatchewan is complicated by a series of agronomic and pest management issues. These include damage from the lesser clover leaf weevil (Hypera nigrirostris F.; LCLW), insecticide toxicity to bee community and unidentified optimal red clover …

Effect of rotation, organic inputs and tillage on crop performance and soil quality in conventional and low-input rotations in central Iowa
… use of longer and more diversified rotations and reduced chemical inputs. In this work we sampled roots and soil parameters at multiple dates and two depths in all cropping phases, in order to quantify changes in physical, chemical and biological soil quality indicators and root responses …

Overseeding Clovers into Permanent Pastures
… seeding method and management variables affected red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) establishment into permanent cool season grass pasture and sod. In the pasture experiment, seedling density was measured two months after sowing and grass, white clover, red …

Quality and yield of tall fescue (Festuca arundinacea Schreb.) as affected by season, legume combinations and nitrogen fertilization
… sativa L.) growth and in 1976, 60-day old red clover (Trifolium pratense L.) growth were used as legume treatments. In 1976, 60-day old orchardgrass (Dactylis glomerata L.) regrowth was fed alone and in a clover mix for comparison. Tall fescue was accumulated from mid-June, July, August, …

Breeding for resistance to clover rot (Sclerotinia spp.) in red clover breeding (Trifolium pratense)
Red clover (Trifolium pratense L.) is a perennial forage crop grown in mixture with grasses or as a pure stand. It is valued for its nitrogen fixation capacity, benefits in organic farming, high quality forage, and beneficial effects on the soil structure. However, the lack of persistence is a …
