در پژوهش حاضر تأثیر کود اوره و آب مغناطیسی بر عملکرد و کارایی مصرف آب و کود در گیاه خیار بررسی شد. پژوهش به صورت آزمایش کرت‌های خرد شده در قالب طرح بلوک‌های کامل تصادفی با سه تکرار در مزرعه تحقیقاتی دانشگاه زنجان در سال 1397 انجام گرفت. تیمارهای آزمایش شامل سطوح کود نیتروژن از منبع اوره در 5 سطح (صفر، 25، 50، 75 و 100 درصد نیاز کودی اوره) و آب آبیاری (مغناطیسی و غیرمغناطیسی) بودند. آبیاری با سیستم قطره‌ای-نواری و کوددهی به صورت کودآبیاری تقسیطی انجام گرفت. نتایج نشان داد اثر سطوح کود اوره بر عملکرد میوه، کارایی مصرف آب و کود، تعداد میوه، سطح برگ و شاخص کلروفیل معنی‌دار بود. تیمار آب مغناطیسی بر کلیه صفات مورد ارزیابی بجز شاخص کلروفیل اثر معنی‌داری داشت. اثر متقابل تیمارهای آزمایش بر صفات کارایی مصرف آب و کود اوره و تعداد میوه معنی‌دار شد. بر اساس یافته‌ها، متوسط عملکرد، کارایی مصرف آب و کود اوره تیمار آب مغناطیسی به ترتیب 9/14، 13 و 5/110 درصد بیش‌تر از آب غیرمغناطیسی شد. نتایج نشان داد بهترین سطح کود اوره، 75 درصد نیاز کودی اوره بود که در شرایط استفاده از آب مغناطیسی نسبت به آب غیرمغناطیسی عملکرد، کارایی مصرف آب و کود را به ترتیب 4/18، 4/18 و 0/78 درصد افزایش داد.
