چکیده

به‌منظور تعیین مناسب‌ترین آرایش کاشت کلزا رقم زرفام، آزمایشی در دو سال 1389 و 1390 به‌صورت کرت‌های خردشده در قالب طرح بلوک‌های کامل تصادفی در چهار تکرار در مزرعه ایستگاه تحقیقات کشاورزی ورامین اجرا شد. کرت­های اصلی شامل روش کاشت یک خط روی پشته 60 سانتی‌متری، دو خط روی پشته 60 سانتی‌متری، دو خط روی پشته 50 و یک خط روی پشته 50 سانتی‌متری و کرت‌های فرعی شامل میزان بذر 6، 8 و 10 کیلوگرم در هکتار بودند. نتایج تجزیه مرکب دوساله نشان داد که اثر برهمکنش روش کاشت در مقدار بذر بر تعداد روز تا جوانه‌زنی، روز تا رسیدگی، تعداد خورجین در بوته و وزن هزار دانه معنی‌دار بود. مصرف بذر تا 8 کیلوگرم نتایج خوبی داشت و با افزایش تعداد ردیف و کاهش فاصله کاشت بذرها عملکرد و ویژگی‌های عملکردی کاهش یافت. از روش کاشت یک خط روی پشته 60 سانتی‌متری بیشترین تعداد دانه در خورجین و درصد روغن حاصل گردید. همچنین روش کاشت یک خط روی پشته 60 سانتی‌متری و 8 کیلوگرم بذر در هکتار در اکثر صفات مورد بررسی نتایج مناسبی داشت؛ بنابراین در کاشت کلزا روش کاشت یک خط روی پشته 60 سانتی‌‌‌متری و مصرف 8 کیلوگرم بذر در هکتار توصیه می‌شود.

چکیده [English]

To determine the best planting pattern of rapeseed cv. Zarfam, an experiment was carried out during two years of 2010 and 2011 at Agricultural Research Station of Varamin, Iran. The experiment was in split-plot design based on complete randomized block with 12 treatments and four replications. The main plots included four planting methods including one or two rows on furrow with 60 or 50 cm spacing and the sub plots included three seed rates of 6, 8 and 10 kg/ha. Combined analysis showed that interaction between planting methods and seed rates was significant on day to germinate, day of ripening, and number of silique per plant and weight of 1000 seed. Planting method of one row on furrow with 60 cm spacingcaused longest period of crop maturity, number of pod per plant, number of seed per silique, 1000 seed weightand oil percentage.Seed rate up to 8 kg had proper resultsandincreasing the number of rows and reducing space between caused decrement in yield and yieldcomponents.The method of one row planting on furrow with 60 cm spacing had the most seed number in silique and oil percentage. Also, 60 cm spacing on one row and 8 kg/ha seed rate had suitable effect on most of the studied traits would be recommendable for rapessed cv. Zarfam in this region.
