Studies on Interaction and Managment of Wild Oats in Spring Wheat: Weed Ecology and Management Imtiaz Khan

Results showed that wild oats is an aggressive weed and reduces the grain yield of wheat even if present at density of one plant m-2 in wheat fields. However, the yield reduction is dependent on wild oat density i. e. higher the wild oats density, greater will be the yield losses of wheat. Presence of wild oats decreased all the yield components of wheat whereas the greatest reduction was recorded in tillers. It was concluded from the results of two years of experimentation that presence of wild oats density even at 1 m-2 caused substantial yield losses, hence it must be controlled to mitigate the yield and quality losses of wheat. Herbicide carfentrazone ethyl ester is proved to be best herbicide for controlling wild oats in spring wheat. It is thus recommended that judicious thinking is desired to manage different wild oats biotypes infesting farmers fields.
