In recent literature, very few studies have reported the use of the combination of indicators from ecological communities and ecotoxicity biomarkers in field experiments to assess agricultural quality. Therefore, the aim of this study was to determine the influence of three soil management practices of vine inter-rows (chemical weeding, mechanical weeding and grass-covering) on earthworms, in t...

Mechanical weeding is an important tool in organic farming. However, the use of mechanical weeding in conventional agriculture is increasing, due to public demands to lower the use of pesticides and an increased number of pesticide-resistant weeds. Ground nesting birds are highly susceptible to farming operations, like mechanical weeding, which may destroy the nests and reduce the survival of c...

It can be difficult to automatically generate “nice” graphical representations for concept lattices from lexical databases, such as Roget’s Thesaurus, because the data sources tend to be large and complex. This paper discusses a variety of “data weeding” techniques that can be applied in order to reduce the size of a concept lattice, first, in general and then with respect to Roget’s Thesaurus....

Farming organic vegetable and crops have grown as a market desiring commodity. Weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. A few chemicals are commonly applied in organic farming. Thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...

The present study evaluated the effects of different dosages herbicides Oxyfluorfen and Trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. In this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

This study was undertaken to evaluate natural mulches for weed control in organic onion (Allium cepa) production where current practices rely on hand-weeding or plastic mulch. Three experiments were conducted over 2 years, with two experiments conducted on-farm in different years and one experiment conducted on-station. Treatments consisted of hand-weeding or mulches of wheat (Triticum aestivum...
