Abstract :

In order to study the effect of  applying different herbicides on the properties of wheat, an experiment was conducted in the farming year 2011-2012 on the research farm of agriculture faculty of Islamic Azad University Arak branch, in the form of split plot in the random perfect blocks base plan mode with 12 tretments in 3 repetitions. The treatments included the main factor of herbicides 2-4-D %75 DF, Tribenuron methyl %72 SL and the combination of 2-4-D %75DF + Tribenuron methyl %72SL and the minor factor of herbicides consumption different times included initial establishment, Tillering, stemming and witness with no consumption of herbicides. The experiment results showed that the witness treatment (with no consumption of herbicides), 89.33 cm high and that the consumption of herbicides 2-4-D at the time of stemming brought about the highest (86.33 cm) bush in the spraying using herbicide 2-4-D at wheat stemming was 41.88g. The most weight of straw and mulch was also reported to be 1638.70 g at the time of spraying using the combination of herbicides 2-4-D and Granstar at stemming meanwhile, the least wheat density was at the time of spraying using Granstar at initial establishment.
