چکیده

آزمایشی با هدف بررسی اثر سطوح مختلف آبیاری و کود ورمی­کمپوست بر عملکرد و میزان بهره­وری آب آبیاری محصول کینوا به­صورت کرت­های خرد شده بر پایه بلوک­های کامل تصادفی در سال 1400 در مزرعه تحقیقاتی دانشگاه کردستان واقع در شهرستان دهگلان انجام شد. تیمارهای آزمایش شامل چهار سطح آبیاری  شامل 50، 75، 100 و 125%،  نیاز آبی گیاه کینوا و متغیر فرعی شامل چهار سطح کود ورمی­کمپوست صفر، 5، 10 و ton/h 15 بود. روش آبیاری مورد استفاده در این آزمایش از نوع سیستم آبیاری قطره‌ای –نواری بود. میزان آب آبیاری توسط یک کنتور حجمی تعبیه شده بر روی لوله اصلی اندازه‌گیری گردید. نتایج نشان داد بالاترین عملکرد دانه کینوا معادل kg/h 2375 در تیمار 125% نیاز آبی و ton/h 15ورمی­کمپوست، عملکرد بیولوژیک kg/h 5560 در تیمار 100% نیاز آبی و ton/h 15 ورمی­کمپوست مشاهده شد. بیشترین مقادیر بهره­وری آب مصرفی و کارایی مصرف آب در تیمار 50% نیاز آبی بود. همچنین کاربرد ton/h 15 ورمی­کمپوست موجب افزایش معنی­دار بهره­وری آب مصرفی و کارایی مصرف آب در مقایسه با تیمار شاهد شد. بالاترین شاخص برداشت کینوا در تیمار 125% نیاز آبی گیاه به دست آمد.

چکیده [English]

To investigate the effect of different levels of vermicompost and irrigation on the yield and irrigation water efficiency of Quinoa, this experiment was conducted as a split plot based on a randomized complete block design in the research field of the University of Kurdistan located in Dehgolan in 2021. The experimental factors included four levels of irrigation water 50, 75, 100, and 125% of the water requirement of the quinoa crop and the variable included four levels of vermicompost fertilizer to 0, 5, 10, and 15 tons/ha, respectively. The irrigation method used in this experiment was a drip-strip irrigation system. The amount of irrigation water was measured by a volumetric meter installed on the main pipe. The highest yield of quinoa seed equaled 2375 kg/ha was observed in the treatment of 125% of the water requirement and 15 tons/ha of vermicompost and a biological yield of 5560 kg/ha in the treatment of 100% of the water requirement and 15 tons/ha vermicompost. The highest values of water consumption efficiency and water use efficiency were observed in the treatment of 50% water requirement. The application of 15 tons/ha vermicompost caused a significant increase in water use efficiency compared to the control treatment. The highest quinoa harvest index was observed in the treatment of 125% of the crop water requirement.
