Abstract :

Survey effects of  new herbicides on control of weed and  ear characteristics  of  maize, an experimental was carried out  as complete randomized block design with three replications in the research station of Islamic Azad University- Arak Branch, Iran in 2012. Three different herbicides were applied after maize emergence, namely Nicosolfuron, Rimsolfuron  and (Rimsolfuron +Nicosolfuron) With treatment weeding in compared to twice Weeding and Weedy checktreatment in the maize variety Sc-704. Results showed that  application of  Rimsolfuron +Nicosolfuronat+ Weeding decreased weeds dry weight as compared to Weedy checktreatment by 88.96%.  Application of  Nicosolfuron at rate of 2 liter per ha-1  decrease weeds dry weight as compared to Weedy checktreatment by 37.22%  that  between  herbicide treatments had least effects. The maximum of grain yield equal 4514 kg/ hawas obtained from Rimsolfuron +Nicosolfuronat + Weeding.
