Abstract Interest in organic farming is growing rapidly in Europe. The resulting expansion of the organic farming area has been expected to enhance the biodiversity of agricultural habitats. Organic cropping practices can be hypothesized to support a higher number of weed species than conventional cropping and also to favor herbicide-susceptible and ...

Weed Research, 2008
SummaryInternational trade is a major route by which non‐indigenous organisms are introduced into new habitats. Various kinds of weed seeds have been introduced through grain trade. The objectives of this study were to understand the factors that affect the initial assemblage of plant species introduced by the international grain trade and to extract ...

Changes in the Weed Species Composition of the Southern United States: 1974 to 1995
Weed Technology, 1997The Southern Weed Science Society has conducted an annual survey of the most troublesome weeds in several major crops since 1971. The objective of this summary was to characterize shifts in weed populations over a 22-yr period in four major agronomic crops.

Species composition of weeds in various crop rotations of the Mari El Republic
Вестник российской сельскохозяйственной наукиThe article presents the results of long-term experiments to determine the species composition of weed vegetation, the dynamics of weeds on crops in various crop rotations is established. In order to develop rational measures to control weeds, their species and quantitative composition were studied.

Chemical composition and in vitro digestibility of some weed species during summer
Australian Journal of Experimental Agriculture and Animal Husbandry, 1971Weed species were collected during the first three months of 1967 at Canberra and arbitrarily divided into those parts that were easily accessible to sheep and those that were not. The digestibility and nitrogen content of whole plants of some weed species and the more readily accessible parts of other species compared favourably with those of sown ...

Can conversion to organic farming restore the species composition of arable weed communities?
Biological Conservation, 2007Abstract Benefits of organic cropping for biodiversity have usually been demonstrated in relation to modern conventional cropping. In this study, the ability of organic cropping to restore species composition of weed communities was explored by comparing weed communities of present day organic cropping with weed communities at the beginning of the ...
