“…Pinnerup (1982) and Froud-Williams et al (1983). On the other hand, however, Andersen (1987) and Skuterud et al (1996) wrote that the method of tillage did not show any eff ect on the abundance of this species.…”

“…Gruber et al, 2012;Pollard & Cussans, in Tørresen & Skuterud, 2002). The reason why some annual species occur more frequently consists probably in the fact that in the reaction to a reduced depth of soil processing some species produce more seeds so that the number of specimens in the soil weed seedbank is gradually increasing (Schwerdtle, 1977;Froud-Williams et al, 1983). Many authors very o en reported perennial species as typical weeds occurring in minimum tillage systems (Boström & Fogelfors, 1999;Locke et al, 2002;Streit et al, 2002;Tørresen & Skuterud, 2002).…”

The semipilot-scale fi eld experiment was established in the cadastre of the village Letkovice in the South Moravian Region (Czech Republic). The study area was situated in a warm climatic region T2. Winter wheat was cultivated in two variants of tillage, viz. conventional tillage (CT) and minimum tillage (MT) and a er three diff erent forecrops (fodder beet, late potatoes, and broad (faba) bean). Weed infestation of wheat stands was evaluated in spring seasons of 2007 and 2008, always before the application of herbicides. Numbers of weed specimens and their species were defi ned by means of a calculation method. Recorded data were processed by means of multidimensional analyses of ecological data, viz. Data Correspondence Analysis (DCA) and Redundancy Analysis (RDA). Within the study period, altogether 22 weed species were identifi ed in all variants with diff erent tillage technologies and diff erent forecrops. In the MT variant, the degree of winter wheat stand infestation with weeds was lower. As far as the forecrops were concerned, the most and the least intensive degrees of infestation were recorded on plots with faba bean and late potatoes, respectively.

“…decrease (Derksen et al 2001) in density in ZT cropping systems. Dandelion (Froud-Williams et al 1983;Derksen et al 1993;Arshad et al 1994;Moyer et al 1994) and perennial sowthistle (Miller and Nalewaja 1985;Derksen et al 1993) have previously been found to increase in density in ZT systems. Lamb's-quarters and wild mustard were associated with MT and stinkweed and volunteer wheat were associated with CT.…”

. 2001. Tillage intensity and crop rotation affect weed community dynamics in a winter wheat cropping system. Can. J. Plant Sci. 81: 805-813. Development of improved weed management systems requires more knowledge on how various weed species respond to changing agronomic practices. A long-term study was conducted to determine weed population responses to various tillage intensities and crop rotations in a winter wheat (Triticum aestivum L.) dominated cropping system. Weed density and species composition differed with tillage, rotation, year, and date of sampling within years. Weed community dynamics were most affected by year-to-year differences in environmental conditions, followed by crop rotation, and then tillage intensity. and its use in canola resulted in an increase in these species in a winter wheat-canola rotation. Total weed densities were often greater in zero tillage than in either minimum or conventional tillage. Russian thistle, downy brome, kochia, and redroot pigweed (Amaranthus retroflexus L.) were associated with zero tillage while wild buckwheat (Polygonum convolvulus L.), lamb's-quarters (Chenopodium album L.), flixweed, and wild mustard (Sinapis arvensis L.) were associated with conventional tillage. Perennials such as dandelion and perennial sowthistle (Sonchus arvensis L.) were associated with zero tillage but Canada thistle was associated with conventional tillage. Information will be utilized to implement more effective weed management programs in winter wheat production systems. . L'utilisation de cet herbicide dans les cultures de canola augmente la densité des peuplements de ces espèces dans l'assolement blé d'hiver-canola. En général, les adventices sont souvent plus nombreuses quand on ne travaille pas le sol que lorsqu'on le travaille un peu ou normalement. La soude roulante, B. tectorum, le kochia à balais et l'amarante racine rouge (Amaranthus retroflexus L.) affectionnent les champs non travaillés tandis que la vrillée bâtarde (Polygonum convolvulus L.), le chénopode blanc (Chenopodum album L.), le sisymbre sagesse et la moutarde sauvage (Sinapis arvensis L.) préfèrent les terrains remués de la manière habituelle. Les vivaces comme le pissenlit et le laiteron des champs (Sonchus arvensis L.) sont associés au non-travail du sol, mais le chardon des champs se retrouve là où on retourne la terre. Les données de l'étude serviront à élaborer des programmes de lutte contre les mauvaises herbes plus efficaces pour la production du blé d'hiver.

“…lntent Agricultural research will also be more concerned in prob ing the "memory" of agricultural systems than in monitbring the short term response to particular interventions. T1nre ton[-term memory of a system may be manifested in changes in weed populations with tillage practices (Froud-Williams et al 1983), or changes in pasture species with grazing management, or changes in nutrient cycling with fertility management (Bagayoko et al 1992 …”

The structure and function of agricultural research. Can. J. Plant Sci. 76: 603-{10. Contemporary agricultural research is founded upon short-term conholled studies to examine, screen, and rank performance of genetic improveients or managerial processes. This approach has performed admirably in support of the resource-intensive, highlyielO paraAigm which has guided agricultural development since the second World War. Changes to this paradigm, which riay occui in ..rlponr. to economic, rocGtal, or environmental issues, may require increased emphasis on farm-based, system-orienied research to complement the experiment-station-based research which has proven so successful to date' Corresponding changes to the form, structuri, intent, and ultimately, the beneficiaries of agricultural research are discussed.
