I report the current status of the heavy-light decay constants, the bag parameters and the semileptonic form factors. I compare the heavy-light decay constants with Wilson-Wilson and clover-clover fermions. Systematic errors such as scale setting and renormalization factors are also discussed. 1/M dependences for the heavy-light semi-leptonic form factors near q = q m ax with clover-clover and ...

Clovers (genus Trifolium) are widely cultivated across the world as forage legumes and make a large contribution to livestock feed production and soil improvement. Subterranean clover (T. subterraneum L.) is well suited for genomic and genetic studies as a reference species in the Trifolium genus, because it is an annual with a simple genome structure (autogamous and diploid), unlike the other ...

We study exceptional modes of both the Wilson and the clover action in order to understand why quenched clover spectroscopy suffers so severely from exceptional configurations. We show that, in contrast to the case of the Wilson action, a large clover coefficient can make the exceptional modes extremely localized and thus very sensitive to short distance fluctuations. We describe a way to optim...

Better persistence and reliability of white clover (Trifolium repens L.) is critical in achieving a more competitive New Zealand farming industry. To persist, white clover must establish well and withstand the accumulated stresses of competition from associated grasses, grazing, variable soil fertility, drought, plus pest and disease pressure. These factors vary markedly with environment and fa...

Soil organic nitrogen was quantified by solid-state " N cross-polarization nuclear magnetic resonance spectroscopy (NMR) during a I4-month laboratory incubation of a sandy loam soil amended with '5N-clover. In whole soil and particle-size fractions, the clover-derived N was always 85-90% amide, 5 10% guanidinium N of arginine, and 5% amino. Quantitativeness of these results was suggested by (1)...

Řepková J., Nedělník J. (2014): Modern methods for genetic improvement of Trifolium pratense. Czech J. Genet. Plant Breed., 50: 92–99. This review focuses on trends in genetic improvement of a significant representative forage crop, Trifolium pratense (red clover) classified taxonomically into the agronomically outstanding family Fabaceae. Red clover breeding is aimed at improving traits like p...

The intake of isoflavones and the resulting equol contents of both plasma and milk of the same red clover-fed cows are reported for the first time in cyclic change-over design study. Cows were fed four different red clover silages and two timothy-meadow fescue silages as controls. The red clover silages contained daidzein, formononetin, biochanin A and genistein, whereas the timothy-meadow fesc...

Kura clover (Trifolium ambiguumM. Bieb.) grown in monoculture is difficult to harvest mechanically because of its decumbent growth habit, and legumes in general have poor ensiling characteristics. Our objectives were to assess forage yield, nutritive value, and silage characteristics of kura clover–winter wheat (Triticum aestivum L.) mixtures to determine usefulness as a silage crop. ‘Cardinal’...

Field assessments were conducted to examine the interplay between host plant and predation in complex agricultural mosaic on pea aphid clover and alfalfa races. In one experiment, we examined the relative fitness on clover race (CR) and alfalfa race (AR) pea aphids on broad bean, red clover and alfalfa alone. But because clover is typically grown in a more complex agricultural mosaic with alfal...

Milk production of fall-calving dairy cows during subsequent summer grazing was evaluated in two consecutive years using a total of 80 mid- to late-lactation Holsteins. Cows calved during September and October and grazed from April to August in the following year. In yr 1, 27 cows grazed a native grass pasture and 13 cows grazed a native grass-clover mixed pasture containing 26% red clover and ...
