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 …

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, …

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.)
Use of legumes as an alternative to nitrogen (N) fertilization in pasture management improves forage quality 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 …

Effects of overseeded legume living mulches and tillage on weed suppression and broccoli yield
… 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 from …

Isoflavonoid induction and nitrogen assimilation in AM colonized red clover
… 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 determine the …

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. …

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 …

Mob stocking effects on herbage nutritive value, herbage accumulation, and plant species composition
… in establishment of seeded clovers: red clover [Trifolium pratense L. Cinnamon Plus] establishment was similar among stocking methods but white clover [Trifolium repens L. Will] establishment was greater in continuously stocked pastures than mob and rotationally stocked pastures. Hand-clipped …

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 …

The agronomic and economic performance of flax in Iowa
… (L.) Merr.] or corn (Zea mays L.). Red clover (Trifolium pratense L.) was underseeded with flax at time of sowing. Nitrogen was applied as composted swine manure, liquid swine manure, or urea. Each source of N was applied at a rate to supply 30, 60, and 90 lb N acre-1. A control where no N was …

Effect of rotation, organic inputs and tillage on crop performance and soil quality in conventional and low-input rotations in central Iowa
… though the 3-yrrotation included red clover (Trifolium pratense L.) instead of alfalfa (Medicago sativa L.), a shorter rotation length, and significantly greater mean annual organic inputs than did the 4-yr rotation. Corn yield in the 3-yr LEI rotation was significantly higher than that …

Quality and yield of tall fescue (Festuca arundinacea Schreb.) as affected by season, legume combinations and nitrogen fertilization
… 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, and September, …
