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 …

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 …

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 …

Effect of several insects on the chemical composition of alfalfa, red clover, and birdsfoot trefoil
… definite numbers of the insect. Six month old red clover, alfalfa, and birdsfoot trefoil plants were exposed for a month to spittlebug infestations of 0, 50, 100, and 150 adults. Although the spittlebug mortality was lowest when reared on alfalfa and highest on birdsfoot trefoil, yellowing …

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 …

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 …
