چکیده

به‌منظور بررسی برخی خصوصیات کمی و کیفی علوفه تاج خروس زراعی تحت اثر برخی تیمارهای پیش از کاشت بذری، آزمایشی بر پایه طرح بلوک کامل تصادفی با شش تیمار و سه تکرار در مزرعه تحقیقاتی دانشگاه ارومیه در سال 1393 انجام گرفت. تیمارها شامل پیش‌تیمار بذری کود کبوتری (به نسبت یک در 10)، ونیاز تغلیظ شده 39/68 درصد (به نسبت سه در 1000)، کود نانو کلات سوپر میکرو کامل (به نسبت سه در 1000)، آب مغناطیسی، همیوپاتی x12 و شاهد (بدون پیش‌تیمار) بودند. بذرها به مدت هشت ساعت در تیمارهای ذکر شده غوطه ور شدند، سپس به مدت 24 ساعت در دمای 25 درجه سانتی گراد به رطوبت اولیه رسانده شدند و جهت کشت به مزرعه منتقل شدند. برداشت علوفه در مرحله گلدهی مزرعه، از مساحت یک متر مربع هر واحد آزمایشی انجام شد. در این آزمایشوزن خشک ساقه، برگ، نسبت برگ به ساقه، وزن خشک علوفه، عناصر پتاسیم، فسفر و کلسیم علوفه، وزن بذر، درصد روغن، عملکرد روغن، درصد پروتئین و عملکرد پروتئین مورد ارزیابی قرار گرفتند. اثر تیمار بر صفات وزن خشک ساقه (5/306 گرم در متر مربع)، برگ (8/255 گرم در متر مربع)، خشک علوفه (7/7809 کیلوگرم در هکتار) و عناصر فسفر (8/3 گرم در کیلوگرم)، کلسیم (4/20 گرم در کیلوگرم)، وزن بذر (2/1797 کیلوگرم در هکتار)، درصد روغن (2/12)، عملکرد روغن (5/217 کیلوگرم در هکتار)، درصد پروتئین (3/13) و عملکرد پروتئین (5/234 کیلوگرم در هکتار) معنی دار و افزایشی بود. در تحقیق حاضر اعمال تیمارهای پیش از کاشت آب مغناطیس و کود کبوتری از نظر حصول خصوصیات کیفی اثرگذاری بیشتری نسبت به سایر پیش‌تیمارها داشتند.

چکیده [English]

To study the effect of seed priming on forage and seed quality and quantity of cultivated amaranthus, a field experiment was conducted as randomized completely block design with six treatments and three replications in experimental of college of agriculture of Urmia University on 2013 cropping season. Treatments were seed priming of pigeon manure (10%), concentrated vaniaz 68.39% (3*1000) super macro plus nano chelate fertilizer (3*1000), magnet water, Homeopathy 12x and control. The seeds were soaked in the listed treatments for 8 hours; therefore those were brought to the initial moisture content for 24 hours at 25C.therefore those were brought to the initial moisture content for 24 hours at 25 ◦C and transmitted to field for planting. Harvest was at flowering stage in one square meter of each experimental unit. In current study were including Steam dry matter, Leaf dry matter, Leaf to stem ratio, Forage yield, P, K, C and seed yield, oil percent and yield, protein percent and yield were evaluated. Treatment effect on steam dry matter (306.5 gr m-2), leaf (255.8 gr m-2), Forage yield (7809.7 kg ha-1), CaO (20.4 gr kg-1), P2O5 (3.9 gr kg-1), seed yield (798.2 kg ha-1), oil % (12.2%), oil yield (217.5 kg ha-1), protein % (13.8%), protein yield (234.5 kg ha-1) was significant and increasing. According to obtained results, using magnetic water and nano chelate pretreatment was lead to quantitative enhancement more than others.
