Abstract
To evaluate the reaction of some sweet corn varieties to new urea sulfonyl and mixture herbicides, an experimental research based on a randomized complete block factorial design with three replications was conducted. The first and second factor were sweet corn variety and chemical control included nicosulfuron (Cruz), nicosulfuron (Cruz) + bromoxinyl+MCPA (brimicide MA), foramsulfuron (equip), Rimsulfuron +Nicosulfuron (Ultima), Mesotrion+ S-Metolacholor+ Terbuthlazine (Lumax 537.5 SE), with three cultivars of sweet corn including golden (KSC403su), Merit and Chase, weed free, weed infested with three replication in each block. Assessment rate included injury sweet corn on EWRC, sweet corn varieties and weeds biomass at 4 weeks after spraying. Merit variety was ruined by nicosulfuron, nicosulfuron+ bromoxinyl+MCPA, rimsulfuron and foramsulfuron +nicosulfuron application as susceptible cultivar, and Golden and Chase with minimum injury by these herbicides usage known as tolerance varieties. Mesotrion+ S-Metolacholor+ Terbuthlazine was only herbicide which applicable on Merit variety. The herbicides effect was significant on stem diameter, leaf number, plant dry weight, plant height, ear length, ear diameter, cob weight and grain weight per ear. The highest and lowest grain yield related to Chase and Merit varieties, respectively. Golden variety had medium grain yield between two varieties. Also, the result showed that red root pigweed, common purslane, binweed, common lambsquarter, purple nutsedge, black nightshad density and dry weight reduced by all of the herbicides compared control treatment, significantly. Totally, Mesotrion+ S-Metolacholor+ Terbuthlazine were only herbicide that applicable in all of sweet corn varieties without any injury to crop and high effect to all weeds control.
