| کمآبیاری و انتخاب رقم مناسب از راهکارهای مطلوب جهت مصرف بهینه آب به‌ویژه در مناطق خشک و نیمهخشک هستند. بر این اساس آزمایش بهصورت کرت‌های خرد شده بر پایه بلوک‌های کاملاً تصادفی در سه تکرار در دو سال 1394 و 1395 بر روی گوجهفرنگی در دشت مغان در شرایط مزرعهای اجرا شد. تیمارها شامل چهار سطح آبیاری IR1 (100 درصد نیاز آبی)، IR2 (80 درصد نیاز آبی)، IR3 (70 درصد نیاز آبی) و IR4 (50 درصد نیاز آبی) بهعنوان عامل اصلی و ارقام تجاری گوجهفرنگی (Cul1: سوپربیتا، Cul2: 08و Cul3: متین) بهعنوان عامل فرعی بودند. نتایج حاصل از مقایسه میانگین داده‌ها نشان داد که کمآبیاری موجب کاهش عملکرد، اجزاء و بهرهوری آب و افزایش صفات کیفی (مواد جامد محلول، ویتامین ث وpH میوه) در تمامی ارقام میشود. بر اساس نتایج تحقیق حاضر در شرایط مغان رقم 08 از نظر عملکرد و رقم سوپربیتا از نظر صفات کیفی برترین ارقام در شرایط آبیاری نرمال و کمآبیاری بودند. | ||

| چکیده [English] | ||
| Deficit irrigation and suitable choice of variety are essential optimization methods for water consumption in irrigated special in arid and semi-arid area. In order to, an experiment was conducted in a split plot arrangement based on randomized complete block design with three replications in Moghan plain under field condition at 2015 and 2016 years. Main-plot was Normal irrigation (IR1), 80 percent of full irrigation (IR2), 70 percent of full irrigation (IR3) and 50 percent of full irrigation (IR4). Cultivar included Super Bita (Cul 1), 08 (Cul 2) and Matin (Cul 3) as a sub-plot. The results of comparing the means of the data demonstrated that deficit irrigation decreased water productivity and yield of all cultivars and increased quality characteristics (TSS, present C Vitamin and pH) of all cultivars. Therefore, 08 was the best variety under normal irrigation and water deficit conditions about yield and Super bita was the superlative variety about quality characteristics to the deficit irrigation in Moghan Plain. | ||
