چکیده

به منظور ارزیابی اثرگذاری‌های کود­های شیمیایی و زیستی بر غلظت عناصر نیتروژن، فسفر و پتاسیم، ویژگی­های بیوشیمیایی و عملکرد کاسه­های گل چای ترش (مکّی)، آزمایشی به صورت طرح کرت­های خردشده در قالب بلوک­های کامل تصادفی در سه تکرار در مزرعة تحقیقاتی دانشگاه زابل در سال­های 1392 و 1393 اجرا شد. عامل اصلی شامل کودهای شیمیایی با سه سطح فسفر، نیتروژن و NPK و عامل فرعی شامل کود زیستی با پنج سطح نیتروکسین، سوپرنیتروپلاس، سوپربیوفسفات، قارچ‌ریشه (میکوریزا) و بدون کاربرد کود زیستی بودند. نتایج به‌دست‌آمده از تجزیة مرکب دو سال زراعی نشان داد که تأثیر تیمار کودهای شیمیایی و زیستی بر همة صفات مورد بررسی معنی­دار (01/0P£) بود. تأثیر برهمکنش کودهای شیمیایی و زیستی برای همة صفات مورد بررسی به جز میزان نیتروژن، پروتئین و فسفر برگ معنی­دار شد. بیشترین میزان نیتروژن برگ و کاسبرگ، میزان پروتئین برگ و کاسبرگ، میزان پتاسیم کاسبرگ، محتوای آنتوسیانین کاسبرگ، محتوای ویتامین C کاسبرگ، میزان اسیدیتة کاسبرگ و عملکرد کاسه­های گل در تیمار تلفیق کود شیمیایی NPK با کود زیستی نیتروکسین به‌دست آمد. بیشترین میزان فسفر برگ و کاسبرگ در تیمار کود شیمیایی NPK در تلفیق با کود زیستی سوپربیوفسفات به‌دست آمد. بنابراین با توجه به ضرورت تولید گیاهان دارویی در نظام­های زراعی، کاربرد کودهای شیمیایی به همراه کودهای زیستی برای بهبود کارایی کاربرد کودهای شیمیایی در راستای دستیابی به کشاورزی پایدار و حفظ محیط‌زیست توصیه می­شود.

چکیده [English]

To evaluate the effect of chemical and bio-fertilizer on nitrogen, phosphorus and potash concentration, biochemical traits and calyxes yield of roselle, an experiment was conducted in the split plot based on randomized coplete block design with three replications, at the Research Station in Zabol University, during 2013 and 2014. The main plot consisted of three levels: phosphorus, nitrogen and NPK fertilizer and the subplot involved five levels: Nitroxin, supernitroplus, superbiosulphate, mycorrhizal and non-bio-fertilizer. The results of combined analysis of variance showed that the effects of chemical and biological fertilizers were significant (P≤0.01) for all studied traits. Interaction of chemical and biological fertilizer was significant for all traits except for percentag of leaves nitrogen, phosphorus and protein. The highest values for the percentage of leaves and sepals nitrogen, leaves and sepals protein, percentage of sepals potash, sepals anthocyanin content, sepals vitamin C content, sepals acidity and calyxes yield belong to the NPK fertilizer in combination with nitroxin bio-fertilizer treatment. The highest values for the percentage of leaves and sepals phosphorus triates belong to the NPK fertilizer in combination with superbiophosphate bio-fertilizer treatment.Thus, with respect to the production of medicinal plants in cropping systems, the use of chemical fertilizers with bio-fertilizers to improve the efficiency of chemical fertilizers in order to achieve sustainable agriculture and environmental protection are recommended.
