dc.description.abstractThis chapter examines the importance of crop competition to weed management. Improvements in the competitive ability of crops can be achieved by breeding and by crop management, and often crop management has a larger effect on weed management than crop genotype. Weeds cause significant losses in yield and reduce the quality of grain crops. Whenever two plants grow near to one another, they will interact by altering the environment in which they grow, which influences their acquisition of these resources and their growth. Plants can sense the presence of neighbors through changes in the ratio of red:far red light even before the onset of competition for physical resources. There is some evidence that roots can respond to the presence of neighboring roots and can distinguish roots from the same plant from roots of neighboring plants, which has been described as "self" versus "non-self" recognition. However, what impact such recognition systems have on the behavior of different species and the outcome of competition has not been investigated.-
