چکیده

فراهمی عناصر ریزمغذی از طریق تغذیه گیاهی می‌تواند به رشد گیاه و تأمین نیاز انسان به این عناصر کمک نماید. در آزمایشی بر روی لوبیا چشم‌بلبلی اثر تیمارهای محلول‏پاشی سولفات روی (عدم کاربرد، کاربرد غلظت‌های2 و 4 گرم در لیتر سولفات روی)، محلول‏پاشی سولفات آهن (عدم کاربرد، کاربرد غلظت‌های 3 و 6 گرم در لیتر سولفات آهن) و پرایمینگ بذر با پلی‏اتیلن‏گلایکول 6000 (بدون پرایم و کاربرد پرایم ( bar2- )) به­صورت فاکتوریل در قالب طرح پایه بلوک‌های کامل تصادفی با سه تکرار در بهار 1396 در مزرعه پژوهشی دانشگاه علوم کشاورزی و منابع طبیعی خوزستان بررسی گردید. نتایج نشان داد پرایم بذر بر سرعت و درصد سبزشدن گیاه‏چه و اکثر صفات مورد بررسی اثر منفی داشت. بیش‌ترین عملکرد دانه (3784 کیلوگرم در هکتار)، عملکرد پروتئین (1114 کیلوگرم در هکتار) و شاخص برداشت (9/39 درصد) به‌ترتیب در اثرات متقابل سه‌گانه بدون پرایم × عدم کاربرد روی × محلول‌پاشی سولفات آهن (3 گرم در لیتر)، بدون پرایم × عدم کاربرد سولفات روی × عدم کاربرد سولفات آهن و بدون پرایم × عدم کاربرد سولفات روی × کاربرد سولفات آهن (6 گرم در لیتر) مشاهده شد. نتایج کلی نشان داد که کاربرد آهن و روی در غلظت‌های پایین می‌تواند تاحدودی باعث بهبود برخی صفات رشدی گیاه لوبیا شود، اما پرایم بذر بر صفات رشدی این گیاه تاثیر چندانی نداشت.

چکیده [English]

Plant access to micronutrients helps to plant growth and the human need for these elements by eating vegetative food. In order to investigate the effects of foliar spraying of zinc sulfate (0, 2 and 4 g.l-1 of zinc sulfate), iron sulfate (0, 3 and 6 g.l-1 of iron sulfate) and seed osmopriming (control and polyethylene glycol 6000 (-2 bar)) an experiment was carried out in factorial based on a randomized complete block design with three replications at the research farm of Agricultural Sciences and Natural Resources University of Khuzestan (spring, 2017). The results showed that seed priming had a negative effect on most traits including seedling emergence percentage, seedling emergence rate (SER) and mean emergence time (MET). It was also observed that the highest grain yield, protein yield, and harvest index were obtained from triple interactions effects of non-priming × non-application of zinc sulfate × application of iron sulfate (3 g.l-1), no priming × non-application of zinc sulfate × non-application of iron sulfate, non-priming × non-application of zinc sulfate × application of iron sulfate (6 g.l-1) respectively. The general results showed that the application of iron and zinc in low concentrations can be somewhat improved bean plant growth traits. But seed priming had little effect on the growth traits of this plant.
