Abstract
Among the technological factors that contribute to the yield of maize, the fight weeds is a mandatory requirement. In 2007, a factorial yield test was performed at the Agricultural Research and Development Station (ARDS) Turda, where was studied the influence of the two systems, the classic (CS) and the minimum tillage one (MT) on the weeds and the yield maize, for a period of 12 years. Generally the total number of weeds in MT was higher (343 pcs. m-2 ) than CS (324 pcs.m2), because, without soil inversion, weed seeds remained in the soil surface layer where climate conditions stimulated weed germination. The cultivation of maize in minimum tillage system could be recommended as a viable alternative to the classical system in the hilly area from Transylvania, this recommendation is also based on the rather small quantitative differences (133 kg ha-1 ) between the two tillage systems.
