چکیده

به منظور بررسی اثر سطوح مختلف آب و کود بر کارایی مصرف آب، عملکرد و درصد پروتئین دانه گندم، آزمایشی به مدت دو سال زراعی در ایستگاه تحقیقات کشاورزی و منابع طبیعی بروجرد اجرا شد. آزمایش با استفاده از طرح کرت‎های دوبار خرد شده در 3 تکرار انجام شد. پلات اصلی شامل سطوح آب مصرفی (6000 I2= و 5000 I1= و 4000 I0= متر مکعب  در هکتار) و  پلات فرعی سطوح کـودی شامـل F1=NPK+ME، ME 3/1 +F2=NPK و ME 7/0 +  F3=NPK ، مـنـظور از «ME » مصـرف عناصـر کـم مصـرف شامل آهن ، روی ، منگنز ، مس و بور و پلات­های فرعی-فرعی شامل ارقام مرودشت، M -75-7 و M -75-10 بودند. میانگین دو ساله تیمارهای مورد بررسی نشان داد که بالاترین عملکرد دانه از مصرف سطح کودی F1 و سطح آبی I1 (5000 مترمکعب آب) برای رقم M-75-10 به دست آمد. بیشترین کارایی مصرف آب از کاربرد تیمار کودی F2 و سطح آب مصرفی I0 مربوط به رقم مرودشت بوده و بیشترین پروتئین دانه از کاربرد سطح آبی I0 و سطح کودی F0 برای رقم M -75-7  به دست آمد.

چکیده [English]

In order to study the effect of various irrigation water levels and fertilizers on water use efficiency, yield and seed protein content, a two year field experiment was conducted in agricultural and natural resources research station of Broujerd. Experiment was carried out in a split split plot design in three replicate. Main plot was involved three irrigation water levels (I0=4000, I1=5000, I2=6000 m3) and three levels of fertilizer including F1=NPK+M, F2=NPK+1.3M and F3=NPK + 0.7M are allocated to sub plot. M means microelement consumption including iron, zinc, manganese, copper and boron. Sub sub plot was allocated to three wheat cultivar including Marvdasht, M -75-7, M -75-10. Two years results of studied treatments showed that highest seed yield is related to M-75-10 cultivar; highest water use efficiency is related to Marvdasht cultivar and highest protein content is related to M-75-7 cultivar.
