Sažetak
Barnyardgrass (Echinochloa crus-galli L. ) is annual narrow-leaved weed from the Poaceae family. The success of this weed species may be attributed to large seed production, easy seed dispersal, seed dormancy, ability to flower under different photoperiods and existence of biotypes resistant to herbicides. Therefore, barnyardgrass is considered one of the most important weed species in the world. In Croatia it is ranged on the first place of the most common annual narrow-leaved weed in summer crops. Barnyardgrass is a cosmopolitan species with an area of distribution of 63 °N to 55 °S latitude. It is capable of adapting to different climatic conditions and its biological minimum varies, depending on climate, from 5.5 to 10.8 ° C. It can germinate even at high water stress conditions (-0.97 MPa) as well as in a wide pH range of soil (4.7-8.3). With its presence in crop, depending on the density and growth stage of crop, it can significantly reduce potential yield of row and vegetable crops.
