چکیده مقاله :

به منظور بررسی اثر چند علف کش بر مهار علف های هرز و عملکرد و اجزای عملکرد سه رقم ذرت، آزمایشی به صورت کرت های خرد شده در قالب طرح بلوک های کامل تصادفی با چهار تکرار انجام شد. علف کش های مورد بررسی شامل ارادیکان، ارادیکان + توفوردی و لاسو + توفوردی در کرت های اصلی و رقم ذرت شامل سینگل کراس 604 ، 700 و 647 در کرت های فرعی قرار داده شدند. اثر تیمار علف کش بر صفت وزن خشک علف های هرز معنی دار بود. در تیمار لاسو + توفوردی حداقل وزن خشک علف هرز در متر مربع به دست آمد. این علفکش، همچنین از کارایی بیشتری در مهار علف های هرز نسبت به سایرین برخوردار بود. عملکرد دانه، طول و قطر بلال نیز تحت تأثیر علف کش قرار گرفتند. اثر رقم بر وزن هزار دانه نیز معنی دار شد و رقم 647 ظرفیت تولید بیشتری نسبت به سایر ارقام داشت. بالاترین عملکرد دانه ذرت از مصرف پس رویشی لاسو و توفوردی حاصل گردید. بنابراین، استفاده از این تیمار به دلیل مهار مؤثر علف های هرز به ویژه در اوایل دوره رشد ذرت که از توان رقابتی کمی برخوردار است قابل توصیه می باشد.

چکیده انگلیسی:

To study the effect of herbicides on weeds control and yield and yield components of three corn cultivars,  an experiment was conducted in split plot experiment based on randomized complete block design with four replications. The herbicides included Eradican, Eradican + 2,4-D, and Laso + 2,4-D assigned in main plots and maize cultivars included SC604, SC700, and SC647 SC were placed in in subplots. The effect of herbicide on dry weight of weed characteristics was significant. The lowest weed dry weight per square meter was obtained from the treatment of Laso + 2,4-D. In comparison to other herbicide, this herbicide also had more efficiency in weeds control.  Grain yield, ear length and ear diameter were also influenced by herbicide. The effect of cultivar on 1000-grain weight was meaningful and SC647 had higher production capacity compared to other cultivars. The highest yield of corn was obtained from combination treatment of post-emergence of Laso and 2,4-D. Therefore, it is recommended to use this treatment because of the effective control of weeds, especially in the early period of corn growth, which has little competitive ability.
