In order to evaluate the effect of integrated weed management on the yield quality and quantity of Sugarcane, variety CP69, a field experiment was conducted during 2009-2010 at the Argo-Industrial farm of Deabel-e-Khozaie located on the Southeast of Ahvaz. The research was a randomized complete block design (RCBD) with 3 replications, including 9 diferent control mathods in three groups (i.e. Chemical, Agronomical and Integrated) with three replications. The control methods were 1: the combination of Atrazin and Ametrin+2.4D by the ratio of 5kg and 2.5kg + 2litre; 2: The combination of E.P.T.C +Metribuzin by the ratio of 8litre +2kg. 3: The combination of Tebuteyouran + Atrazin and Ametrin + metribuzin by the ratio of 2liter + 2kg and 3kg + 2kg in the hectar, respectively (Chemical Control). 4: only Sugarcane leaves; 5: only cultivation; 6: The combination of Bagas and mud (Agronomical). 7: The integration of Atrazin and Sugarcane leaves. 8: The combination of E.P.T.C and cultivation; 9 The combination of Tebuteyouran + Atrazin by the ratio of 2liter + 2kg and mud + bagas, respectively (integrated methods). The yield quality and quantity and yield components of Sugarcane and the weed's status were calculated. Results showed that the highest Cane's diameter, weight of main stem, cane yield and sugar yield were obtained in integrated method, treatment No. 8 (including herbicide & cultivation). Also, the best sugar quality including sugar purity and polarity was obtained in this treatment (i.e. method No. 8). Inaddition, based on these results we found that integrated approches had a higher quality and quentity for sugarcane yield compared to other methods (i.e. chemical & agronomical methods). Therefore, for ideal weed management and reduction of herbicide use, the integrated herbicide with interrow cultivation was the best weed management method in sugarcane.

Sugarcane is a tropical plant and a member of the poaceae family which, despite its low tolerance to cultivation in chilly climates shows no resistance to planing them in subtropical region. In order to evaluate different management methods in sugarcane fields damaged by cooling and yield reduction, a completely randomized block design (RCBD) was carried out with 3 replications and the 4 treatments (CP 48-103 cultivar) in 2008-2009 in Amirkabir Sugar cane company in the south of Ahvaz. The treatments were cutting of plant residue (Base Cutting), burning, application of Cytokinins hormone, and control. The results showed that the treatments had no significant differences in stalks numbers while the treatments of hormones and Base Cutting were significant in height, and the Base Cutting treatment had a maximum height. The Base Cutting, Burning and hormones treatments had significant differences in chlorophyll rate of leaf blade. Qualitative properties such as Recoverable Sugar (R.S) marked no significant differences between other treatments. The sugarcane yield showed a significant difference, where the treatment of Base Cutting had highest yield, but in the case of sugar yield production there were no differences between the treatments. Control, cutting of plant residue, burning and application cytokinins hormone treatments yield were 55375, 57625,56562 and 49125 kg/ha cane and 4651, 4955, 4049 and 4092 kg/ha sugar, respectively. Results indicated that when chilling occurring injury, the suitable economic method is leaving the injured fields without any field practices.
