“…Weed management practices to prevent the emergence of plants of these species in the off-season periods are also very important. Winter plants such as rye (Secale cereale L.) and radish (Raphanus sativus L.) can reduce the emergence of I. grandifolia (Bittencourt et al 2013). Crop rotation allows the use of herbicides with an alternative mechanism of action, avoiding the evolution of herbicide resistant weeds.…”

“…In the integrated and ecological agriculture systems, more attention is being paid to what can be the longest possible period of soil coverage with plant mulches and mulches from straw after cereal grain harvest (Liebman and Davis 2000;Bàrberi 2002;Economou et al 2002;Campiglia et al 2010;Bittencourt et al 2013). When straw from plants is left in the field as mulch, erosion is reduced, and the biological activity of the soil increases, both of which efficiently inhibit the growth of weeds (Hembry and Davies 1994;Teasdale and Mohler 2000;Duppong et al 2004;Grassbaugh et al 2004;Rogers et al 2004;Ramakrishna et al 2006).…”

An investigation was done on the effect of different types of organic mulches that were applied in form of straw to the soil mulching process, on the weed infestation, number, and fresh mass of weeds in broccoli cv. Milady F 1 (Brassica oleracea L. var. italica Plenck) and tomato cv. Polfast F 1 (Lycopersicon esculentum Mill.) grown under polypropylene fibre as a covering, or grown without a covering. The different types of organic straw mulches were: rye (Secale cereale L.), corn (Zea mays L.), rape (Brassica napus L. subsp. napus), and buckwheat (Fagopyrum esculentum Moench.). All the organic mulches were applied at a dose of 10 t/ha. The effect of the mulches was compared to a control plot which had no mulch. The type of organic mulch applied to the soil mulching process influenced species composition, number, and fresh mass of weeds. This effect could be the result of the properties of the mulch (colour, structure, etc.) or the allelopathic effect on the germination and growth of individual weeds species. Irrespective of the investigated factors, 24 and 25 weeds species, respectively, were observed immediately after cover removal and before broccoli and tomato harvest.In the first date of estimation Chenopodium album L., Echinochloa crus-galli (L.) P. Beauv., Fallopia convolvulus (L.) Á. Löve, Stellaria media (L.) Vill., and Viola tricolor L. dominated, however, before the vegetables were harvested Ch. album, V. tricolor, Veronica arvensis L., and E. crus-galli dominated. An application of polypropylene fibre contributed to an increase in the number and fresh mass of weeds in both vegetables in the first date of estimation (after cover removal). During this period, vegetables cannot compete with weeds. It is important to note, though, that before the vegetables were harvested, a decrease was found in the number and fresh mass of weeds in the covered plots. The most efficient weed limiter, both after cover removal and also before the broccoli and tomatoes were harvested, was buckwheat and rye straw, respectively.

“…Experiments had revealed a progressive reduction of weed infestation with the increasing on the cover crops residues amount. However, different responses has been reported resulting from interaction between cover crop species and weeds (Bittencourt et al, 2013).…”

The use of cover crops can contribute to the reduction of the dose required for weed control. The aim of this work was to assess the growth of weeds and productivity of corn from different degrees of black oat cover and velvet bean and atrazine doses. Two experiments were conducted in the experimental area, both was conducted in randomized blocks in a split plot design with four replications. In the main plots were randomized, four straw levels (0, 0.75, 1.5 and 3 times the amount originally produced) oat (Exp 1) or velvet bean (Exp 2). In the subplots were randomized to four doses of atrazine (0, 2100, 4200 and 8400 g ha -1 ). It was evaluated the weed density and crop yield. The utilization of straw species coverage on the ground, even at high levels, was not enough to exercise total control of weeds. Atrazine was not effective in weed control only in the treatment with 2100 g ha -1 of the herbicide and no velvet bean straw on the ground, but the straw of this species realized suppressive effect, supplementing the effect of the herbicidal dose. Levels in 2775 and 5550 kg ha -1 of velvet bean straw reduce the productivity of corn. Integrating the use of oat or velvet bean straw with low dose of atrazine (2100 g ai ha -1 ), results in effective weed control systems and more suitable cropping systems in the environmental aspect, both by reducing the use of herbicides as taking advantage of the benefits of no-till system.
