چکیده

چکیده      به منظور تعیین اثر کمپوست کرمی و کود مرغی بر عملکرد و اجزای عملکرد سیب زمینی در شرایط کرمانشاه، آزمایشی به صورت فاکتوریل در قالب طرح بلوک­های کامل تصادفی با تیمارهای کمپوست کرمی در چهار سطح صفر شاهد، 3، 6 و 9 تن در هکتار و کود مرغی در چهار سطح 0، 10، 12 و 14 تن در هکتار با سه تکرار در ایستگاه تحقیقاتی ماهیدشت کرمانشاه اجرا شد. تعداد ساقه و غده در بوته، وزن غده و عملکرد غده به طور معنی داری با مصرف کمپوست کرمی و کود مرغی افزایش یافتند. اثر متقابل کمپوست کرمی و کود مرغی نشان داد که بیشترین‌عملکرد‌ غده ‌سیب‌زمینی در تیمار 3 تن کمپوست کرمی و 10 تن کود مرغی و کمترین مقدار عملکرد متعلق به تیمار بدون کود بود، بطوریکه عملکرد در تیمار 3 تن کمپوست کرمی و 10 تن کود مرغی در مقایسه با شاهد دو برابر گردید. تیمار 3 تن کمپوست کرمی و 10 تن کود مرغی بیشترین تأثیر را بر تعداد غده در بوته داشت. همچنین، بیشترین وزن غده و تعداد ساقه در بوته در تیمار 3 تن کمپوست کرمی و 12 تن کود مرغی به دست آمد. بررسی همبستگی­ها نشان داد رابطه  مثبت و معنی­داری بین تعداد ساقه در بوته و عملکرد نهایی وجود داشت. به طور کلی، بر اساس عملکرد سیب زمینی مصرف 3 تن کمپوست کرمی و 10 تن کود مرغی برای افزایش تولید محصول سیب زمینی توصیه می­گردد.

چکیده [English]

To determine the effect of vormicompost and chicken manure on potato yield and yield components in Kermanshah climate condition, a factorial experiment based on randomized complete block design with three replications was conducted with four vormicompost rates of 0 as control, 3, 6 and 9 t/ha and poultry manure rates of 0, 10, 12 and 14 t/ha. Number of stems and tubers per plant, tuber weight and tuber yield significantly increased with chicken manure and verrmicompost application.  Interaction between vormicompost and chicken manure showed that the potato received 3 t/ha of vermicompost and 10 t/ha of chicken manure caused the highest yield two times more than control. This treatment had the highest effect on the number of tubers per plant.Also, the highest tuber weight and number of stems per plant were obtained in 3 t/ha of chicken manure and 12 vormicompost and 12 t/ha, respectively. Correlation evaluation showed that there was a significant positive relationship between the number of stems per plant and final yield.Generally, 3 t/ha of vormicompost and 10 t/ha of chicken manure was recommended to increase potato yield production.
