Previous studies have suggested that phenolics from legume green manures may contribute to weed control through allelopathy. The objective of this study was to determine how decomposition of red clover (Trifolium pratense L.) residue affects phytotoxicity to a weed species, wild mustard (Sinapis arvensis L.). Red clover (1.25 g), 30 g acid washed sand, and 5 ml of microbial inoculant were incub...

Clovers and other legumes are highly desirable species in pastures and hay meadows. First, legumes are able to obtain nitrogen from air through their symbiotic relationship with Rhizobium bacteria and, there­ fore, are not dependent on nitrogen fertilizer. The fixed nitrogen is primarily used to support clover growth, but parts of it become avail­ able to neighboring grass plants when clover ti...

Some floral pigments (including antioxidants); carotenoids, chlorophylls, anthocyanins and xanthophylls were determined colorimetrically in some honeybee, Apis mellifera L., products; citrus, clover and cotton honeys, three types of beeswax; white, brown and dark and propolis; brown, dark brown and dark. Two solvents (acetone or ethanol) were used for extraction and determination of pigments at...

I discuss a study performed by the SCRI lattice gauge theory group which compared light hadron spectroscopy using the Wilson and Clover fermionic actions. We showed that a Clover coefficient chosen using tadpole-improved tree-level perturbation theory effectively eliminates the O(a) discretization errors present in the Wilson action. We found that discretization errors in light spectroscopy for...

The true digestibility of amino acids of 5 groups of different Trifolium varieties and hybrids was established by using the balance method adapted for geese. Digestibility of the most important amino acids Lysine varies from 70.40 (for tetraplod red clover) to 81.78 (for medium leafy white clover varieties); for Methionine from 60.54 (for Trifolium repens f. giganteum) to 89.42 (diploid red clo...

We discuss a 3-flavour lattice QCD action with clover improvement in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links for the clover term. With the (tree-level) Symanzik improved gluon action this constitutes the Stout Link Non-perturbative Clover or SLiNC action. To cancel O(a) terms the clover term coefficient has to be tuned. We pre...

Objectives: To critically evaluate the effect of red clover on hot flash, endometrial thickness, and hormones status in postmenopausal and peri- and post-menopausal women. Materials and Methods: MEDLINE (1966 to July 2014), Scopus (1990 to July 2014), and the Cochrane Central Register of Controlled Trials (The Cochrane Library issue 1, 2014) were searched for published randomized controlled Tri...

BACKGROUND AND AIMS Increasing soil salinity poses a major plant stress in agro-ecosystems worldwide. Surprisingly little is known about the quantitative effect of elevated salinity on secondary metabolism in many agricultural crops. Such salt-mediated changes in defence-associated compounds may significantly alter the quality of food and forage plants as well as their resistance against pests....

SUMMARY The production of pol ygalacturonase in associations of nodule bacteria and seedlings of leguminous plants was investigated. Plants and bacteria were combined in the following ways : (a) different plant species were combined with infective strains (isolated from the same cross inoculation group) as well as non-infective ones (from foreign groups) ; (b) host plant species with different ...

1. Tropospheric ozone (O 3 ) and carbon dioxide (CO 2 ) are significant drivers of plant growth and chemical composition. We hypothesized that exposure to elevated concentrations of O 3 and CO 2 , singly and in combination, would modify the chemical composition of Trifolium and thus alter its digestibility and nutritive quality for ruminant herbivores. 2. We tested our hypothesis by collecting ...
