Abstract

The experiment was conducted in one of Salah Aldeen province’s fields in Aldjel city during the fall season of 2016.This experiment used herbicides namely Lumax with the active material of S-metochlor+terbthylazine+Mesotrion at the recommended 3L.h dose in presence and absence of the residue from the last season and half of the recommended dose in presence and absence of the residue, all have done with and without herbicide control. A second herbicide namely Camix with an active ingredient of S-metochlor +Mesotrion was used at  the recommended dose in presence and absence of the residue from the last season and  half of the recommended dose in presence and absence of the residue, all have done with and without  herbicide control. The experiment was implemented according to Randomized Complete Block Design (RCBD) with three repetitions. The results showed that percent of control increases for all blocks in wide and slim leaf at different concentrations and types of herbicides. Camix  showed highest percentage of control at 2.8 L/h for slim leaf in absence of residue, Lumax showed highest percentage of control at 1.5L/h for wide leaf in present of residue and 3 L/h in absence of residue. Treatment in present of residues showed the highest length of plant, 202 cm, at 3 L/h of Lumax for the slim leaf and the highest leaf area and leaf area index(LAI) , 4890 cm2 and  26.1 respectively. The highest total yield obtained was 3801 ton/h  at 3 L/h of Lumax absence of residues.
