چکیده مقاله :
به منظور تعیین اثر کودهای آلی بر عملکرد و اجزای عملکرد گلرنگ، آزمایشی در مزرعهی پژوهشی دانشگاه آزاد اسلامی واحد شیروان در سال زراعی 92-1391 اجرا شد. تیمارهای آزمایش شامل ورمی کمپوست، کمپوست زبالهی شهری، کود گاوی کاملاً پوسیده و کود شیمیایی بود که در دو محیط آبیاری کامل و کم آبیاری اجرا شد. آزمایش به صورت کرت های خرد شده در قالب طرح بلوک‌های کامل تصادفی با سه تکرار اجرا شد. تیمار آبیاری در کرت های اصلی و تیمارهای کودی در کرت‌های فرعی قرار گرفتند. بیشترین عملکرد دانه در شرایط آبیاری کامل متعلق به تیمارهای کود شیمیایی، 50 تن در هکتار کود دامی، 10 تن در هکتار ورمی کمپوست و 5 تن در هکتار کمپوست زباله شهری بود که با هم اختلاف معنی‌داری نداشتند و در مقایسه با شاهد به ترتیب 9/25%، 4/18%، 4/17% و 15% افزایش عملکرد نشان دادند. در شرایط کم آبیاری استفاده از 15 تن کمپوست زبالهی شهری در مقایسه با تمامی تیمارها عملکرد دانه بیشتری تولید نمود و در مقایسه با تیمار کود شیمیایی 7/25% افزایش عملکرد داشت. بنابراین، در شرایط آبیاری کامل مصرف 5 تن در هکتار کمپوست زباله شهری و در شرایط کم آبیاری مصرف 15 تن در هکتار کمپوست زباله شهری نتیجه مطلوبی داده است و قابل توصیه برای استفاده در زراعت گلرنگ می باشد.
This study was conducted in Islamic Azad University, Shirvan branch during the growing year in 2012-2013 to determine the effect of organic fertilizers on yield and yield components of safflower. The treatments consisted of vermicompost, urban waste compost, cow manure and chemical fertilizer which were applied in two full and limited irrigated conditions. The experiment was conducted in split plot based on randomized complete block design with three replications. Irrigation and fertilizer treatments were conducted in main plot and sub-plot, respectively. The highest seed yield in full irrigated condition obtained from chemical fertilizer, 50 t/h cow manure, 10 t/h vermicompost and 8 5 t/h urban waste compost treatments which had no significant difference with each other but in comparison with check increased seed yield up to 25.9%, 18.4%, 17.4% and 15% , respectively. The highest seed obtained from the application of 15 t/h urban waste compost and was increased 25.7% seed yield in comparison with chemical fertilizer. Therefore, application of 5 t/h urban waste compost in full irrigation condition and 15 t/h in limited irrigation condition had desirable results and it is recommended for safflower production but further studies are needed to confirm these results.
