The effect of grasses grown for seed in mixture with legumes on the incidence of weeds and soil nitrogen content [PDF]

open access: yes, 2002
This report was presented at the UK Organic Research 2002 Conference on behalf of the Colloquium of Organic Researchers (COR). The incidence of weeds and the content of soil nitrogen were investigated in the first year of a field trial with organic ...

Field‐based evidence of impaired sperm quality associated with conventional farming in two passerine birds

open access: yesIbis, EarlyView.
The detrimental effects of conventional farming on bird biodiversity are increasingly documented. Despite this, the specific impacts of both organic and conventional farming practices on bird coloration and sperm quality in natural settings remain unexplored. This study aimed to determine whether these farming practices differentially affect body mass,

Residual effects of cutting and grazing on grass/clover growth [PDF]

open access: yes, 2010
The residual effect of cutting and grazing during the growing season was investigated in the spring and summer growth in an organic crop rotation with 1-4 year-old grass-clover mixtures of white clover (Trifolium repens L.) and perennial ryegrass (Lolium

Natural‐based antioxidants in cosmeceuticals: Extraction, bioavailability and skin ageing applications

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Natural antioxidants from plants, fruits, seeds and fungi combat ageing by neutralizing free radicals, boosting collagen and protecting against UV damage. Enhanced by green extraction and smart delivery systems, they offer powerful anti‐inflammatory and antimicrobial benefits.

Change of the weed seed bank during the first four years of a five-course crop rotation with organic vegetables [PDF]

open access: yes, 2008
In a five-course rotation with organic vegetables (white cabbage, carrot and onion) the weed seed bank was reduced the year after two continuous years with red clover, mainly because of mowing of the second year red clover.

Rhizobial motility preference in root colonization of Medicago truncatula

open access: yesNew Phytologist, EarlyView.
Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

【Short Report】Allelopathic Potential of White, Red and Black Rice CultivarsHisashi Kato-Noguchi1, Kenji Nitta2 and Tomio Itani2

open access: yesPlant Production Science, 2013
The inhibitory effect (allelopathic potential) of shoot, seed and root extracts of 8 white, 5 red and 5 black rice (Oryza sativa L.) cultivars was determined against the seedling growth of lettuce (Lactuca sativa L.) and white clover (Trifolium repens L.)

Nitrogen transfer between clover and wheat in an intercropping experiment [PDF]

open access: yes, 2006
A novel approach to the problem of improving nitrogen supply in organic farming is to use intercropping of cereals with a legume to provide nitrogen transfer within a season and/or to following crops. The affects of intercropping were studied in a column

Tomato Spotted Wilt Virus Reprogrammes Host Glycolysis to Facilitate Proliferation by a Phase‐Separated Co‐Aggregate of Nucleocapsid Protein and Phosphoglycerate Kinase

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Efficient viral proliferation within the host is a critical step in pathogenicity and requires adenosine triphosphate (ATP). The replication, movement and immune evasion of many plant viruses within their hosts are associated with phase separation (PS)‐derived aggregates formed by viral components.

Research in white clover seed production

open access: yesNZGA: Research and Practice Series, 1980
White clover seed yields from crops derived from pure autumn broadcast sowings harvested in the first year after sowing were improved by increasing sowing rate from 3 to 6 kg/ha. On moisture-retentive soils or where irrigation was available, mid-November closings gave highest seed yields for crops derived from either spring undersowings of cereals or ...
