ترجمة الملخص

The experiments were carried out at Deir Ezzor Research Center, Salou Research Station during the growing season 2008 and 2009. The cotton variety Deir Ezzor 22 was grown and the soil was treated, one day before cultivation date, with herbicides: Trifluralin 48% EC at 960 g a i/ ha, Pendimethaline 50% EC at 1320 g a i/ ha Prometryn 50% SC at 1000 g a i/ ha. The broad-leaved weeds were dominated, while narrow-leaved weeds were very lowin the experiments, Prometryn and Trifluralin have shown some insignificant phototoxic symptoms following 30 days of treatment; however these symptoms were sooner disappeared, while Pendimethaline has shown no toxicity on cotton plants.. The hand weeded control was better than other treatments in terms of cotton average plant height. recorded 91.75-92.13 and 96 cm, and number of bolls per plant (30.63-40.47) for drip, furrow and traditional irrigation methods respectively., Pendimethaline had higher average plant height 86 cm under the flood irrigation system, and it was between 71.25-81.88 cm for other treatments,. While the non weeded control had the lowest average plant height 61.38 cm. The weeded control treatment had the highest yield under traditional irrigation method 4368 kg/ha. Trifluralin was better than other treatments in term of number of bolls per plant reached 31.34; also this treatment was the best in terms of yield estimated to 2226 kg/ha under furrow irrigation method. The yield in Prometryn treatment was low and arranged between 531.3-907.6 kg/ha for three irrigation methods, and. there is no significant differences between this treatment and noon weeded control. Trifluralin was the best in reduction of broad-leaved weeds and better than other herbicides treatments recording after 30 days of application 81.-82.8 and 75.6% for drip, furrow and traditional irrigation methods respectively, and kept superiority after 45 and 60 days from treatment with efficiency of 60.3-71.2% after 60 days for three irrigation methods. Trifluralin and Pendimetha line treatments were better than Prometryn in controlling of narrow-leaved weeds after 30-45-60 days from treatment. at efficiency 100%, after 30 days, and kept superiority with efficiency of 69-100% for booth herbicides after 60 days from treatment for three irrigation methods, while the efficiency in Prometryn treatment was very low in controlling booth broad-leaved and narrow-leaved weeds at 16effectiveness of 33-40-50% after 60 days of treatment for drip, furrow and traditional irrigation methods respectively
