Abstract: To evaluate a new method of weed control in Corn (Zea mays) fields of Fars province of Iran and integrating in row cultivation and band spraying of Atrazine in fields of this region and their effects on yield and weed control during 2004 and 2005 crop season a new sprayer with band and broadcast spraying ability was designed and used in corn fields. Results of the first year showed band and broad cast spraying alone or combined with cultivator application in any plant heights increased yield and gave adequate weed control. In rows cultivator applications in any plant heights had not any effect on yield increasing and weed control alone. The second year results showed increasing of yield by using cultivator, but timing of cultivation had not any effect on yield. Band and broad cast spraying combined with cultivation and timing of cultivation gave similar maize yield. These results allow us to extrapolate the band application and mechanical weeding practice in the farm management of corn in Fars province.
