چکیده

     به منظور بررسی تأثیر کودهای آلی و شیمیایی نیتروژنی و فسفردار بر درصد روغن و برخی خصوصیات زراعی گلرنگ رقم محلی اصفهان، آزمایشی در سال 1392 به صورت فاکتوریل در قالب طرح پایه بلوک­های کامل تصادفی با سه تکرار انجام شد. تیمار مصرف کود دامی در سه سطح شامل عدم مصرف کود دامی (شاهد)، مصرف 20 تن در هکتار کود دامی و مصرف 40 تن در هکتار کود دامی و تیمار ترکیب کودهای شیمیایی در چهار سطح شامل عدم مصرف کود­های شیمیایی (شاهد)، مصرف 25 کیلوگرم در هکتار فسفر +50 کیلوگرم در هکتار نیتروژن، مصرف 50 کیلوگرم در هکتار فسفر + 100 کیلوگرم در هکتار نیتروژن، مصرف 75 کیلوگرم در هکتار فسفر + 150 کیلوگرم در هکتار نیتروژن بود. نتایج نشان داد که اثر متقابل کودهای شیمیایی در کود دامی بر صفات تعداد شاخه فرعی فرعی، عملکرد بیولوژیکی بوته­، درصد نیتروژن دانه، کارایی فیزیولوژیک فسفر، کارایی زراعی فسفر و بازیافت ظاهری فسفر معنی دار بود. به طوری که تیمار مصرف 25 کیلوگرم در هکتار فسفر + 50 کیلوگرم در هکتار نیتروژن خالص + 40 تن در هکتار کود دامی با میانگین 88/65 کیلوگرم بر کیلوگرم و تیمار مصرف 25 کیلوگرم در هکتار فسفر + 50 کیلوگرم در هکتار نیتروژن خالص + 20 تن در هکتار کود دامی با میانگین 21/6 کیلوگرم بر کیلوگرم به ترتیب بیشترین و کمترین مقدار کارایی فیزیولوژیک فسفر را داشتند.

چکیده [English]

The effect of organic fertilizers, chemical nitrogen and phosphorus on oil content and some of agronomic traits of safflower (Carthamus tinctorius), was studied in 2014. A factorial arrangement of treatments in a randomized complete block design with three replications was used. Animal manure treatments (M1= Control, M2= 20 ton.ha-1, M3= 40 ton.ha-1), and Chemical fertilizer treatments (F1= Control, F2= 50 kg.ha-1 of nitrogen + 25 kg.ha-1 of P2O5, F3= 100 kg.ha-1 of nitrogen + 50 kg.ha-1 of P2O5, F4= 150 kg.ha-1 of nitrogen + 75 kg.ha-1 of P2O5) were assigned in plots. In this study characteristics such as: stem diameter, number of sub branch, number of kernels per m-2, biological yield, phosphorus agronomic efficiency, grain weight of capitol, phosphorus physiological efficiency, oil content, nitrogen content of grain, number of unfertile capitol, phosphorus appear recovery and capitol diameter were assessed. Results indicated that the interaction effects of chemical fertilizer and animal manure on the characteristics such as: number of sub branch, biological yield, and nitrogen content of grain, phosphorus agronomic efficiency, phosphorus physiological efficiency and phosphorus appear recovery was significant. The maximum and minimum of phosphorus physiological efficiency (65.88 and 6.21 kg.kg-1) were obtained in  treatment of 50 kg.ha-1 of nitrogen + 25 kg.ha-1 of P2O5 + 40 ton.ha-1 of animal manure and 50 kg.ha-1 of nitrogen + 25 kg.ha-1 of P2O5 + 20 ton.ha-1 of animal manure, respectively.
