Abstract:

White clover (Trifolium repens) is adapted to moist, fertile soils in temperate zones. Despite its heterozygous allotetraploid nature, it lacks useful genetic variation for survival and growth in semi-arid, infertile soils. Although white clover is apparently genetically isolated in nature, 11 other taxa have so far been found that can be artificially hybridised into the wider gene pool. These species range from annuals to long-lived, hardy perennials with adaptations to stress environments, and they potentially provide new traits for the breeding of more resilient varieties of white clover.

Abstract:

Kura clover (Trifolium ambiguum M. Bieb.) is a rhizomatous perennial legume that is often challenging to establish from seed. Our objectives were to evaluate the effect of planting date (early April, late April, and mid-May), plant material (rhizomes and rhizomes with buds), and rhizome planting density (11, 44, and 178 plants m-2) on establishment of Kura clover. Establishment of the clover was enhanced by early April planting using rhizomes with buds. Kura clover populations increased with increased rhizome planting densities. Establishment of Kura clover at a rhizome density of 178 rhizome

Kura clover (Trifolium ambiguum M.B.) is a persistent rhizomatous forage legume, whose use in the U.S.A. is limited by establishment difficulties in part attributable to nodulation problems. In this study, soil was collected from established stands of Kura clover growing in 9 diverse North American environments. Rhizobia were plant-trapped using Kura clover cv. Endura as host, then rhizobia from nodules fingerprinted using BOX-PCR. The diversity of isolates from North America was then contrasted to that of rhizobia from a single Caucasian environment (Russia), the center of origin for this spe

Abstract:

Kura clover (Trifolium ambiguum M. Bieb.), a rhizomatous, persistent legume native to the Caucasus region, has received recent attention in North America and New Zealand as a pasture and silage crop. It is reported to be resistant to most pathogens affecting other clovers, including Sclerotinia trifoliorum Eriks. (3,4), one of the most destructive pathogens of clovers in northern Europe. Kura clover (cv. KTA202) was established in May 2009 near Mochełek, Poland (53° 13′ N, 17° 51′ E) on a Luvisol soil.

Selective defoliation of the clover at week 35, and 3-4 weeks drought were imposed on high and low fertility treatments in the post-cutting period.

Kura or Caucasian clover (Trifolium ambiguum Bieb.) is a perennial, rhizomatous legume indigenous to Caucasian Russia and adjacent regions (Kannenberg & Elliott,1962; Bryant, 1974). Those agronomic characteristics that lend it potential significance, namely an extensive root-rhizome system, winter-hardiness, resistance to numerous and serious clover pests, and the production of nectar-rich flowers, were enumerated by Parker & Allen (1952). These authors also pointed out that usage of kura clover was hampered by ineffective nodulation. However, in recent years commercial and effective i

Abstract:

Lawns represent one of the largest cultivated areas in urban landscapes, and in the Upper Midwest of the United States, lawns are typically composed of a small number of cool-season turfgrass species. There is increased interest in enhancing areas dedicated to lawns using flowering species for conservation purposes—for example, to support pollinators. In this study we used a model flowering forb, Kura clover (Trifolium ambiguum M. Bieb.), because—like many flowering species of conservation interest—it is slow to establish and is sensitive to grass competition. We varied the Kura clover seeding

Abstract:

Abstract Optimizing nitrogen (N) management is an important factor for sustainable perennial biomass systems. However, N application is costly, both financially and environmentally. Our objectives were to determine: (1) N rate and plant spacing effects on yield and yield components of prairie cordgrass swards and (2) fertilizer N replacement value (FNRV) of kura clover in prairie cordgrass-kura clover binary mixtures. Plots were established in Illinois, Minnesota, South Dakota, and Wisconsin, USA, in 2010. Kura clover was transplanted on 30-cm centers in all treatments in which it was a compon

SUMMARYOnly a few previous studies have analysed the crude protein (CP) fractions of the Cornell Net Carbohydrate and Protein System during the growth period of forage legumes. The objective of the present study was to investigate the changes in CP fractions during the spring growth and summer–autumn regrowth period of five forage legume species (alfalfa (also known as lucerne, Medicago sativa L.), birdsfoot trefoil (Lotus corniculatus L.), kura clover (Trifolium ambiguum M.B.), red clover (Trifolium pratense L.) and white clover (Trifolium repens L.)) grown in binary mixtures with perennial r

For the first time, in the mountain-forest ecosystems of Crimea of parcel organization level adjacent to the beehives of honey bees (Apis mellifera L.), a species composition of plants representing the melittophilic complex has been identified which provides honey bees with pollen and nectar during the entire warm season. The complex includes 57 species of plants where the honey bees that collect pollen or nectar have been registered. The core of the melittophilic complex consisted of 35 species of plants, the proportion of simultaneously flowering (in any period of the season) flowers of each

Abstract:

Abstract The agronomic performance of Caucasian clover in high country grasslands was the subject of two experiments at Lake Heron Station, Canterbury. In the first experiment, Caucasian clover was direct drilled into an undeveloped pasture (soil pH = 5.5; Olsen P = 7 mg/ litre) with fertilisers containing similar P and S but ± 20 kg/ha of N, in December 2011. After 11 months, shoots of Caucasian clover were small (3 mg), indicating an inoculation failure, and effects of fertilisers were not biologically meaningful. Therefore, the influence of rhizobia inoculant, superphosphate and lime on ear

Bieb.) is a potentially valuable forage legume, but it has been underutilized. A major reason is the difficulty of establishing it from seed. Since kura is rhizomatous, there have been attempts to propagate it vegetatively, but no reports of success at the field scale. Two harvesting methods were tested to transplant material from a mature 17-ha field to a newly tilled 17-ha field: a bermudagrass sprigger that harvests bare rhizome sprigs, and a pot

Abstract:

Kura clover (Trifolium ambiguum) is a perennial living mulch species that can be used in conjunction with zone tillage to reduce nitrogen pollution, maintain ground cover, and provide nitrogen to crops. In such systems, kura clover is maintained between crop rows by limiting tillage only to within-row areas. However, the effect of zone-tilled living mulches on soil quality and nutrient cycling in these distinct regions is relatively unexplored. We examined three pools of labile soil organic matter (SOM): microbial biomass, particulate organic matter (POM), and permanganate oxidizable carbon (P

Abstract:

Kura clover (Trifolium ambiguum M. Bieb.) has been reported to be resistant to several viruses, including Alfalfa mosaic virus (AMV), Bean yellow mosaic virus (BYMV), Clover yellow vein virus (CYVV), Peanut stunt virus, Red clover vein mosaic virus (RCVMV), and White clover mosaic virus (WCMV) (2). Furthermore, 54 of 61 kura clover plants were resistant to Clover yellow mosaic virus (CYMV). Field-grown kura clover plants had no visual symptoms of virus infection, but a small proportion of plant introductions tested positive for CYVV, WCMV, and RCVMV (1). These and similar studies have given ku
