| چکیده | ||
| کشت چغندر علوفه‌ای در پاییز باعث کاهش قابل توجه در آب مصرفی برای تولید علوفه شده و از این منظر دارای اهمیت فراوان است. به همین منظور بررسی عملکرد ارقام مختلف و تاریخ کاشت چغندر علوفه‌ای پاییزه به صورت کرت‌های خرد شده و در قالب طرح بلوک‌های کامل تصادفی با چهار تکرار به مدت دو سال در منطقه کردکوی استان گلستان اجرا شد. فاکتورهای این پروژه عبارت بودند از تاریخ کاشت به‌عنوان عامل اصلی در سه سطح: دهه اول و سوم مهر و دهه دوم آبان ماه، رقم به‌عنوان عامل فرعی در سه سطح، دو رقم خارجی به نام‌های کی‌روش(KYROS) و رقم گریور (GRIOUR) و یک ژنوتیپ داخلی (SBSI 051) بیشترین عملکردریشه و وزن تر اندام‌هوایی از تاریخ کاشت دهه اول مهر حاصل شد، که با تاریخ کاشت دهه سوم مهر از نظر آماری در یک سطح قرار گرفت. در میان ارقام، رقم کی‌روش با عملکرد ریشه 97/1 تن در هکتار بیشترین عملکرد را داشت و ژنوتیپ داخلی با عملکرد 62/29 تن در هکتار حائز کمترین عملکرد بود. در مجموع در بررسی اثرات متقابل، رقم کی‌روش در تاریخ کاشت دهه اول مهر با عملکردریشه 104/46 تن در هکتار به‌عنوان مناسب‌ترین تیمار بود. | ||

| چکیده [English] | ||
| Cultivation of fodder beet in autumn causes a significant reduction in water consumption for fodder production which is a very important issue. For this purpose, to evaluate the effect of planting date on the yield of different autumn fodder beet cultivars , an experiment was performed in split plot based on randomized complete block design with four replications in Kordkuy region of Golestan province. Factors included the planting date as main plot in three levels of the last of September, the first half of October, and November and three cultivars including the Iranian cultivar called SBSI 051 and two foreign cultivars named Kyros and Griour as sub-plot. The highest root yield and shoot weight were obtained from the planting date of the last of September which was statistically at the same level as the planting date of the first half of October. Among cultivars, Kyros and domestic genotype had the highest and lowest root yield of 97.1 and 62.29 t ha-1, respectively. In total and in the study of mutual effects, the Kyros was the most suitable treatment in the planting date of the last of September with root yield of 104.46 t ha-1. The comparison of the two-year results also indicated the superiority of the Kyros with root yield of 97.1 and 15.69 t ha-1 of fresh and dry matter, respectively | ||
