| افزایش جهانی تقاضای آب منجر به کاهش قابل توجه منابع آب شده است و ارزیابی محتوای آب مجازی و عملکرد را برای مدیریت آب کشاورزی بسیار مهم میکند. این پژوهش در سال زراعی 1402 و 1403 برای یک کشت با هدف بررسی اثر مقادیر مختلف زئولیت بر برخی صفات گندم، آب مجازی در شرایط استفاده از آب شور در مزرعه تحقیقاتی دانشکده مهندسی آب انجام گردید. تیمارهای مورد مطالعه در این پژوهش شامل مقدار کاربرد زئولیت (M0: صفر، M1: دو گرم و M2: چهار گرم در هر کیلوگرم خاک در عمق سی سانتیمتری خاک)، نوع زئولیت از نظر دانهبندی (Z1: 1-0 میلیمتر و Z2: 3-1 میلیمتر) و کیفیت آب آبیاری (I1: 5/2 دسی زیمنس بر متر و کیفیت I2: 02/6 دسی زیمنس بر متر) در سه تکرار برای هر تیمار و در 36 کرت آزمایشی بود. طرح آزمایشی مورد نظر به صورت اسپلیت – اسلیت پلات در قالب بلوک کامل تصادفی در کرتهای 1×1 متر مربع پیاده گردید. کیفیت آب آبیاری به عنوان فاکتور اصلی، مقدار زئولیت فاکتور فرعی و نوع زئولیت فاکتور فرعی-فرعی بود. نتایج نشان داد تیمار M2 به طور معناداری عملکرد گندم را افزایش داد. اثر تاثیر کیفیت آب ابیاری بر صفات مورد بررسی در سطح پنج درصد معنیدار بود اما اثر مقدار و اندازه زئولیت و برهمکنش آنها معنیدار نشد. بیشترین عملکرد دانه گندم برحسب تن بر هکتار با مقدار 2/8 در تیمارM2 به همراه I1 مشاهده شد و کمترین آب مجازی بر حسب مترمکعب بر کیلوگرم 66/0 هم مربوط به تیمار تیمارM2 به همراه I1 بود. | ||

| چکیده [English] | ||
| The increasing global demand for water has led to a significant reduction in water resources, making the assessment of virtual water content and yield crucial for agricultural water management. This research was conducted in the crop years 2023-2024 for a single crop with the aim of investigating the effect of different amounts of zeolite on some wheat characteristics and virtual water under saline water use conditions at the research farm of the Faculty of Water Engineering. The treatments studied in this research included the amount of zeolite application (M0: zero, M1: two grams, and M2: four grams per kilogram of soil at a depth of 30 cm), the type of zeolite in terms of particle size (Z1: 0-1 mm and Z2: 1-3 mm), and the quality of irrigation water (I1: 2.5 dS/m and I2: 6.02 dS/m) in three replicates for each treatment and in 36 experimental plots. The experimental design was a split-split plot in a randomized complete block design in 1×1 square meter plots. Irrigation water quality was the main factor, the amount of zeolite was the sub-factor, and the type of zeolite was the sub-sub-factor. The results showed that the M2 treatment significantly increased wheat yield. The effect of irrigation water quality on the studied traits was significant at the 5% level, but the effect of the amount and size of zeolite and their interaction was not significant. The highest wheat grain yield in tons per hectare was 8.2 in the M2 treatment with I1, and the lowest virtual water in cubic meters per kilogram was 0.66, also related to the M2 treatment with I1. | ||
