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 …

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 …

GROWTH, NODULATION AND NITROGEN FIXATION OF ALFALFA (MEDICAGO SATIVA L) AND RED CLOVER (TRIFOLIUM PRATENSE L) AS INFLUENCED BY SOIL ACIDITY AND LIMING
<p>A series of field, greenhouse and laboratory experiments were conducted to examine the influence of soil acidity and liming on the growth of Rhizobium and the nodulation, nitrogen fixation, and yield of alfalfa and red clover.</p><p>In the greenhouse, from soil pH 5.0 to 5.6, nitrogen fixation …

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 …

Isolation and Identification of the Siderophore "Vicibactin" Produced by <em>Rhizobium leguminosarum</em> ATCC 14479.
… ATCC 14479, which infects the red clover <em>Trifolium pratense</em>, was found to produce a trihydroxamate siderophore. Purification and chemical characterization identified this siderophore as Vicibactin that has been found to be produced by other rhizobial strains.</p>

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 …
