The agro-ecological transition aims at reducing the anthropogenic impacts of crop
production on the environment, for instance by decreasing drastically the applications of …

Cereals are among the most competitive of crops, but under organic management, weeds
remain the foremost production problem. Understanding the ecology of both weeds and …

This report shows that weed harrowing in organic cereal fields is an efficient alternative to
herbicides since weed harrowing does not reduce yields compared to weed-free plots …

Kolb LN, Gallandt ER & Molloy T (2010). Improving weed management in organic spring
barley: physical weed control vs. interspecific competition. Weed Research 50, 597–605 …

Composite variables are variables derived from measurable traits. They are commonly used
in agronomy: two well-known examples being the harvest index and the relative water …

Much research on cereal‐weed competition has been directed towards finding cultivars that
have high 'competitive ability'with weeds. I argue that this objective is insufficient, because …

POST weed harrowing and other cultivation methods to control weeds in early crop growth
stages may result in crop damage due to low selectivity between crop and weeds. Crop …

Effective weed management strategies are limited in organic crop** systems because
herbicide use is prohibited. Enhancing crop competitive ability by integrating both cultural …

We investigated the tolerance to weed harrowing of four spring barley varieties and
examined the possible interactions between varietal weed suppressive ability and two …

Physical rather than chemical treatments are preferred for integrated production and are
required for organic production to ensure a sustainable production. Weed management in …
