چکیده
ادوات خاکورزی باید به نحوی انتخاب شوند که ضمن مصرف حداقل انرژی، شرایط مناسب جهت جوانهزنی و رشد ریشه در بستر بذر را در حد مطلوب فراهم آورند. در این تحقیق تأثیر روشهای مختلف خاکورزی شامل (آمادهسازی زمین با گاوآهن برگرداندار و دو دیسک، گاوآهن قلمی و دو دیسک، دو بار دیسک و شاهد (خاکورزی مرسوم) بر اجزای عملکرد محصول گلرنگ (درصد سبز شدن، تعداد غوزه در بوته، تعداد دانه در غوزه، وزن هزار دانه، درصد روغن، عملکرد دانه و عملکرد روغن) و شاخصهای انرژی بررسی شد. نتایج تحقیق نشان داد که از نظر درصد سبز شدن بین تیمارها اختلاف معنیدار وجود داشته، ولی از نظر اجزای عملکرد هیچگونه اختلاف معنیداری وجود ندارد. انرژی ورودی در تیمارها، دارای اختلاف بسیار معنیدار آماری بود که کمترین انرژی مربوط به تیمار دوبار دیسک با میانگین 9652 مگاژول بود. تأثیر روشهای خاکورزی بر انرژی خروجی از مزرعه و بهرهوری انرژی معنیدار نبود. نتایج این تحقیق نشان داد که بیشترین کارآیی انرژی مربوط به روش خاکورزی دوبار دیسک میباشد.

چکیده [English]
Agricultural machineries must be chosen in such a way that provides the best condition for seed germination and root-growth through consuming less energy. In this research, the effect of different tillage methods (moldboard plow with two disks, chisel plow with two disks, two disks and control (Conventional tillage) on yield and energy indexes was studied. The results showed that different tillage methods had significant effect on emergence percentage, but any significant effect in yield components was not observed. Input energy of treatments was qualitatively significant and minimum energy was related to two disks treatments with 9652 MJ. Influence of tillage methods on output energy and energy productivity was not significant. Results revealed that the maximum energy efficiency was related to tillage method with two disks.
