Associating wheat crop and undersown forage legumes in organic agriculture: Incidence of forage legumes species [PDF]

open access: yes, 2010
One of the key issues of organic arable systems is to increase use of N2 fixation from legume plants while enhancing autonomy by the limitation of off-farm inputs. Wheat yield in organic agriculture is generally low and variable.

A bioeconomic model for determining the optimal response to a new weed incursion in Australian cropping systems [PDF]

open access: yes
Invasions by non-indigenous plant species pose serious economic threats to Australian agricultural industries. When an invasion is discovered a decision has to be made as to whether to attempt to eradicate it, contain it or do nothing.

Weed Control with Straw Residues in Occasional Direct Seeding of Faba Bean (Vicia faba sp.) in Organic Agriculture [PDF]

open access: yes, 2010
In order to gain momentum in the consolidation process of no-tillage systems in Europe’s Organic Agriculture, occasional direct seeding (DS) of faba bean (FAB) into a mulch layer of residues from precrop oats should be scrutinized.

Demonstrations of Improved Weed Management Options for Malt Barley in Central Ethiopia Region

open access: yesJournal of Applied Sciences and Environmental Management
Barley (Hordeum vulgare L.) production is seriously affected by weed infestation due to the absence of effective management strategies. A field experiment was conducted to demonstrate the effect of post emergence herbicides on the management of malt ...

Impact of weed infestation on projective soil cover changes during the sunflower vegetation period

open access: yesЛюдина і довкілля: Проблеми неоекології
Weed infestation is one of the key factors influencing the formation of plant cover in agroecosystems. In the context of sunflower cultivation, projective soil cover varies depending on the intensity of weed competition, especially during critical ...

Remote Sensing for Site-Specific Crop Management: Evaluating the Potential of Digital Multi-Spectral Imagery for Monitoring Crop Variability and Weeds within Paddocks [PDF]

open access: yes
This paper analyses the potential and limitations of airborne remote sensing systems for detecting crop growth variability and weed infestation within paddocks at specified capture times. The detection of areas of crop growth variability can help farmers
