چکیده

به منظور بررسی اثر کود ورمی‌کمپوست و کودهای اوره و سولفات‌ آهن بر خصوصیات رویشی و عملکرد دانه آفتابگردان (Helianthus annuus L.) آزمایشی در شهرستان درگز واقع در استان خراسان رضوی در سال 1391 اجرا شد. آزمایش به صورت فاکتوریل در قالب طرح بلوک‌های کامل تصادفی با سه فاکتور و سه تکرار انجام شد. در این آزمایش سه سطح کود اوره (50،150 و 250 کیلوگرم در هکتار) به‌ عنوان فاکتور اول و دو سطح ورمی‌کمپوست (مصرف 7 تن بر هکتار و عدم مصرف) به‌ عنوان فاکتور دوم و دو سطح سولفات‌آهن (مصرف 80کیلوگرم در هکتار و عدم مصرف) به‌ عنوان فاکتور سوم در نظر گرفته شدند. نتایج نشان داد که اثر ترکیب تیماری اوره × ورمی‌کمپوست بر ارتفاع ساقه، قطر طبق، وزن خشک ساقه و عملکرد در سطح احتمال یک درصد معنی‌دار شد. ترکیب 250کیلوگرم در هکتار نیتروژن × ورمی‌کمپوست × سولفات‌ آهن سبب افزایش ارتفاع ساقه، قطر طبق، وزن خشک دمبرگ و ساقه گردید. ترکیب تیماری ورمی‌کمپوست × سولفات‌آهن بر وزن خشک برگ، دمبرگ، ساقه و طبق بسیار معنی‌دار (p≤0.01) بود. کاربرد ترکیب تیماری ورمی‌کمپوست × سولفات ‌آهن بیشترین میزان قطر ساقه، وزن خشک برگ را به همراه داشت. بیشترین عملکرد به مصرف 250کیلوگرم در هکتار نیتروژن× ورمی‌کمپوست تعلق داشت. کاربرد سولفات‌آهن به همراه مقادیر مختلف کود اوره موجب کاهش عملکرد شد. کمترین میزان عملکرد مربوط به ترکیب تیماری 250کیلوگرم در هکتار نیتروژن × سولفات ‌آهن بود. بنابراین چنین به نظر می‌رسد که کاربرد تلفیقی کودآلی ورمی‌کمپوست و کودهای شیمیایی اوره و سولفات‌آهن در منطقه درگز می‌تواند در بهبود خصوصیات رویشی و عملکرد دانه آفتابگردان مؤثر باشد.

چکیده [English]

To study the effect of vermicompost and urea and iron sulfate fertilizers on the growth characteristics and yield of sunflower seed (Helianthus annuus L.) an pediment was conducted in Darreh Gaz located in Khorasan Razavi province in 2012. Factorial experiment in a randomized complete block design with three factors and three repetition. In this experiment three levels of urea (50; 150 and 250 kg per hectare) as the first factor and two level of vermicompost (7 tons per hectare consumption and non-consumption) as the second factor and two iron sulfate (80 kilogram per hectare consumption and non- consumption) were considered as the third factor. The results showed that the effect of urea × vermicompost treatment combination on stem height, head diameter, stem dry weight and yield was significantly at one percent probability level. The treatment combination of 250 kg. ha-1 × iron sulfate× vermicompost increased plant height, head diameter, petiole dry weight. Vermicompost × iron sulfate treatment combination on the dry weight’s leaf, petiole, stem and head were the highest significant (p≤0.01). The application of vermicompost × iron sulfate treatment combination resulted in the highest rate of stem diameter, leaf dry weight and stem the highest yield belonged to 250 kg.ha-1 × vermicompost. Iron sulfate use different amounts of urea fertilizer redact yield. The lowest yield of 250 kg.ha-1× iron sulfate was related to treatment combination. So it seems that the combined application of organic vermicompost fertilizer and urea and iron sulfate fertilizers on the growth and yield of sunflower Darreh Gaz can be effective in improving properties.
