Beet vinasse (BV), a green manure constituted by Trifolium pratense L. uncomposted (TP) and composted with beet vinasse (at 1:1 rate, (TP+BV)1, and 2:1 rate, (TP+BV)2) at 10t organic matter ha(-1) rate were applied during a period of four years for purpose of restoration of a Xelloric Calciorthid located near Seville (Guadalquivir Valley, Andalusia, Spain). The effect on the plant cover, soil p...

To determine if host plant abundance determined the size of clover root weevil (CRW) Sitona obsoletus larval populations, a study was conducted over 4 years in plots sown in ryegrass (Lolium perenne) (cv. Nui) sown at either 6 or 30 kg/ha and white clover (Trifolium repens) sown at a uniform rate of 8 kg/ha. This provided a range of % white clover content to investigate CRW population establish...

BACKGROUND AND AIMS White clover (Trifolium repens) is, due to nitrogen (N) fixation, important to the N dynamics of several northern temperate agroecosystems. This study aimed at monitoring growth and death of major white clover plant organs to assess their potential contribution to within-season N input and risk of off-season N losses. METHODS White clover ('Snowy') was studied in a plot an...

A series of experiments were carried out in order to optimize a protocol for the direct organogenesis of Chilean red clover germplasm. A range of cultivars were used to analyze the effect of explant source (crown or stem meristems of vegetative plants), culture media and plant growth regulators. Our findings showed that stem meristems were easier to obtain, presented lower levels of contaminati...

The oestrogenic activity of certain cultivars of subterranean clover (Trifolium subterraneum, L.) first became known through the observation of serious infertility in ewes in the early 1940's in Western Australia (Bennetts, Underwood and Shier-1946). The manifestations in commercial flocks of the syndrome "clover disease" have been dealt with in the preceding paper (Lightfoot 1974). The deleter...

The responses of selected clones of white clover (Trifolium repens) to simultaneous infection by the southern root-knot nematode (Meloidogyne incognita) and peanut stunt virus (PSV) were determined. Two white clover clones, which were resistant (NC-R) or sensitive (NC-S) to ozone injury, were evaluated. Plant growth and M. incognita reproduction were measured. Root, stolon, and top growth were ...

The genus Trifolium L. belonging to family Fabaceae is represented by about 255 species in the world. Two classifications based on sections or subgenus are commonly used researchers taxonomically evaluation of Trifolium. However, there still some confusing and complex situations taxonomy genus. For this reason, internal transcribed spacer (ITS) regions between rDNA genes nrDNA were examined for...

in a greenhouse experiment, the effects of glomus intraradices and indigenous mycorrhizal isolates from soils under plow and no-till treatments on the uptake of 32p placed at 1, 2.5 and 4 cm from the roots of white clover (trifolium repens) in 23, 37 or 46 days after planting were compared.spores of the indigenous fungi were mostly a mixture of glomus mossea, g. clarum, g. caledonium and g....

in order to estimate the nutrient value of three dominant range species; festucaovina, trifolium montanum and alopecurus textilis via proximate analyses and gas productiontechnique, samples were collected in three stages during grazing period from 26th may to 1thseptember in six areas of sabalan mountain in north west of iran. results showed thattrifolium montanum as a legume had higher values ...
