The presence of scentless chamomile -Matricaria inodora (Matin-Bayer code) in cultivated fields, can result of agricultural practices and adapt it to the potential of that environment. On the podzolic soils of the South part, the weed is perfectly adapted like an invasive species. In dense crops such as: forage grasses, winter barley, winter wheat and fallow land on, weeds vegetate well, proving the potential for competition known and in highlighting the influence of morphology, possible as a result of growing (or not) of these agricultural lands. Biodiversity studies have been performed on numerous capitula and marginal -type flowers namely ligulae, which were analyzed the number and length of their petals. The data obtained showed that the number of flowers had type ligulae maximum frequency depending on the culture: 45/Lolium, 80/barley, 43/wheat and 90/uncultivated land (fallow). Modal value revealed 21 ligulae flowers. The length of the flowers to group around 1.0 cm, to a maximum of 80/Lolium, 60/barley, wheat and fallow land. Both determinations expressed specific asymmetric histograms. Flowers of the type ligulae revealed that the shape of botanical long-petal represented between 4.0 %/wheat and 11.5%/Lolium, from of all scentless chamomile analyzed.
