| چکیده | ||
| به منظور بررسی اثر رقابت چاودار (Secale cereale) با گندم آزمایشی در سال زراعی 1379-1378 در مراکز تحقیقات کشاورزی مشهد و گناباد به صورت سری جایگزینی در قالب طرحهای کامل تصادفی با چهار تکرار در مشهد و سه تکرار در گناباد اجرا شد. فاکتورهای آزمایش عبارت بودند از کشت خالص گندم در تراکم های 450، 460، 470، 490 و 530 بوته در متر مربع و کشت مخلوط گندم و چاودار با تراکم های 10، 20، 40 و 80 بوته در مترمربع چاودار که به صورت مخلوط با 450 بوته در مترمربع گندم کشت گردید و فاکتور دوم شامل دو سطح کنترل و عدم کنترل علف های هرز بود. نتایج به دست آمده نشان داد که چاودار رقیب قوی تری نسبت به گندم می باشد و تقریباً در تمام تیمارهایی که چاودار وجود داشت عملکرد گندم کمتر از کشت خالص بود. البته با تراکم 20 بوته در متر مربع تفاوتها معنی دار نبود. این روند برای عملکرد دانه و همچنین عملکرد بیولوژیک گندم نیز مشاهده شد. نتایج مربوط به کنترل و عدم کنترل علف های هرز نشان داد که تمام تیمارهای عدم کنترل علف های هرز باعث کاهش در عملکرد دانه، عملکرد بیولوژیکی و اجزاء عملکرد گندم شدند. | ||

| چکیده [English] | ||
| In order to analyze the competition of volunteer rye (Secale cereale) with wheat (Triticum aestivum), two experiments were carried out at Mashhad and Gonabad Agricultural Research Stations during the 1998-1999 growing season. In this study, wheat at 450, 460, 470, 490 and 530 plant m-2 and feral rye at of 10, 20, 40, and 80 plants m-2 in association with 450 wheat plants m-2 were considered as the main treatments. The second factor included two weed free and weedy checks. Results indicated that volunteer rye had a higher competitive ability compared to wheat. Wheat yield was significantly lower in treatments associated with rye plants compared to pure stands of wheat. However, at a density of 20 plants m-2 of rye weed, no significant differences in grain as well as biological yield were observed. There were significant differences between weed free and weedy treatments considering grain yield, biological yield and yield components. | ||
