Abstract
Yield losses caused by Bromus sp. in winter cereal in Setif region
range from 40 to 80 %. Bromus rigidus Roth. and Bromus rubens L.
are the most important weeds. In order to formulate non-chemical control
methods, experimental studies were carried out during the period from 1996 to
1999, to determine the effect of burial depth (0 to 25 cm) on seed germination
in three soils, the effect of different plows (disk, molbord, chisel and
cover-crop) and the period of tillage (early and late) on the distribution of
the two species. The results showed that the germination rate ofB.
rigidusseeds in clay soil and sandy soil was null when the burial depth was
more than 15 cm. This rate was less than 20 % for B. rubens in the three
soils when the burial depth exceeds 5 cm. The species infestations are
significantly reduced by early molbord and disk plowing.
