Abstract :
to evaluate the different levels of silicon with the selective of wheat herbicides on control of wild oat, yield and yield components of wheat, was conducted a factorial experiment base on completed block randomized design with three replications in the city Eghlid in crop year 1393.The first factor consisted of seven treatments herbicide application topic , Puma super, Atlantiha, Aperous, Suffix , weedy and weed control, and the second factor has two levels of silicon (application and non-application). The results of dry weight wild oats showed that in terms of silicon utilization increased and were significantly different than the non-application of silicon. The height of dry weight wild oats was related to topic and pumasuper herbicides that in control wild oats weren’t succeeded. Herbicides Atlantis and Suffix herbicides had the height control of wild oats. The results of yield and components yield also showed that the use of silicon in herbicides Topic and Puma super were lead to reduction characteristics. In the case of herbicides Atlantis and Pumasuper in terms of the non-application of silica reduction yield and components yields were observed due to phytotoxicity the effects of herbicides on wheat plants. Silicon is used in treatments of herbicides Aperous and atlantis grain yield were significantly increased. The results showed that the silicon leads to reduce the phytotoxicity of herbicides aperous and Atlantis in weather condition Eghlid.
