چکیده مقاله :

به‌‌منظور بررسی اثر محتوای فسفر اولیه بذر بر خصوصیات رشدی و عملکرد سه رقم جو، پژوهشی به ‌صورت فاکتوریل در قالب طرح بلوک‌های کامل تصادفی در سه تکرار طی دو سال زراعی 1392-1390 در مؤسسه تحقیقات کشاورزی دیم کشور، ایستگاه مراغه انجام شد. عامل اول شامل سه رقم جو سهند، آبیدر و دایتون و عامل دوم نیز مقادیر مختلف فسفر مصرف شده در گیاهان والد در سال قبل 0، 15 ، 30 و 45 کیلوگرم در هکتار از منبع سوپر فسفات تریپل بود. محتوای فسفر دانه بر حسب درصد در گیاهان والد در میزان‌های مختلف فسفر مصرف شده اندازه‌گیری و نتایج نشان داد که در اثر مصرف مقادیر مختلف کود فسفره، غلظت فسفر در بذور تولید شده اختلاف معنی‌دار داشت و تیمارهای 30 و 45 کیلوگرم فسفر در هکتار از نظر غلظت فسفر در بذور نتاج، نسبت به بقیه تیمارها برتر بودند. ترکیب رقم سهند × 30 کیلوگرم فسفر در هکتار به غیر از عملکرد بیولوژیک، از نظر درصد فسفر بذر، عملکرد دانه، در جه باردهی، شاخص برداشت و درصد پوشش سبز در مرحله گلدهی نسبت به بقیه تیمارها برتر بود و این ترکیب تیماری می‌تواند برای کشت پائیزه جو دیم در منطقه و نیز سایر مناطق مشابه آب و هوایی توصیه گردد.

چکیده انگلیسی:

To evaluate the  effects of primitive seed phosphorus content through different phosphorus use on parent plants on growth traits and grain yield of three barley cultivars; a research was conducted as factorial experiment based on randomized complete block design with three replications during 2012- 2013 at Dryland Agricultural Research Institute (DARI), Maragheh station, Iran. Factors were cultivars including Sahand, Abidar and Dayton and primitive seed phosphorous contents that applied in previous year on parent plants at 0, 15, 30 and 45 kg.ha-1 rates. Seed phosphorus percentage was measured in parent plants in different seasons and results showed significant difference in seed phosphorus content through different phosphorus fertilizers application in parent plants and using of 30 and 45 kg.ha-1 of phosphorus fertilizer was more effective than other treatments. Sahand × 30 kg.ha-1 combination was a superior treatment in seed phosphorus content, grain yield, productivity degree, harvest index and green cover percentage but biological yield and can be recommended in fall cultivation of rainfed barley in this and other climatically similar regions.
