The comparative competitiveness to sugarbeet of A. fatua, Alopecurus myosuroides and Stellaria media was also studied. A. fatua competition caused significant loss in the growth, leaf chlorophyll content and yield of sugarbeet. In general, time of A. fatua emergence and plant density were both important factors in determining the severity of crop yield loss. The order of competitiveness seemed to be A. fatua > A. myosuroides > S. media. However, at higher densities no significant causal T2 - Aspects of Applied Biology ER -
