Abstract
The sprouting of weeds was followed over a 9-year period (1977 – 1978 to 1985 – 1986) in a triennial rotation alternating between two spring cultures (barley–pea) and one winter culture (wheat) grown on two agricultural plots. The plots, one superficially worked while the other tilled, did not undergo any weeding treatment. A simultaneous increase in sprouting was observed in both plots at the beginning of the second rotation. However, this increase was greater on the superficially worked plot. The modifications within the adventitious community are qualitative in the first rotation, but become essentially quantitative at the beginning of the second rotation. Some species increase in density (Alopecurus myosuroides, Avena fatua, Galium aparine, Fallopia convolvulus, Sinapis arvensis, Thlaspi arvense) while others decrease (Amaranthus retroflexus, Kickxia spuria, Stellaria media). Key words: community, long term evolution, factorial analysis of correspondences, weeds. [Journal translation]
