| چکیده | ||
| بهمنظور مطالعه تاثیر چند روش کنترل علفهرز بر عملکرد و اجزای عملکرد برنج، آزمایش مزرعهای در سال زراعی 1390 اجرا شد. آزمایش در قالب طرح بلوک های کامل تصادفی در سه تکرار با 7 تیمار شامل دوبار وجیندستی، دوبار وجینکن موتوردار، وجینکن موتوردار+ وجیندستی، دوبار وجینکن کونویدور، علفکش+ وجین دستی، بدون اعمال مدیریت علف های هرز و علفکش یکبار انجام گرفت. نتایج تحقیق حاکی از اختلاف معنی دار بین تیمارها بر صفاتی مانند عملکرد دانه، تعداد دانه در خوشه، تعداد دانه پر و پوک در خوشه، تعداد پنجه بارور، تعداد خوشه، عملکرد بیولوژیک، تراکم و وزن خشک علفهرز بود. بهطورکلی در بین تیمارها، علفکش+ وجین دستی بیشترین عملکرد دانه را بهخود اختصاص داد درحالی که تیمار بدون اعمال مدیریت در این آزمایش بهعلت داشتن تعداد دانه پوک بیشتر در خوشه، تعداد خوشه کمتر، تراکم و وزن خشک بالاتر علفهرز، دارای عملکرد کمتری بود. در بین صفات مورد مطالعه تعداد پنجه بارور و تعداد خوشه بیشترین همبستگی را با عملکرد دانه داشتند. تعداد دانه پوک در خوشه، تراکم و وزن خشک علفهرز نیز با عملکرد دانه همبستگی منفی و معنیداری داشتند. | ||

| چکیده [English] | ||
| In order to study the effects of several weed control methods on yield and yield components of rice, a field experiment was carried out in Babol city- during 2011. The experiment was on the basis of randomized complete blocks design with 3 replications and 7 treatments including hand weeding twice, powered weeding twice, powered weeding+hand weeding, conoweeder weeding twice, herbicide application+hand weeding, weedy check and herbicide application only were used. Results showed that there was significant difference among treatments on grain yield, grain number per panicle, filled grain number per panicle, unfilled grain number per panicle, fertile tillers, panicle number, biological yield, density and dry weight of weed. In general herbicide application+hand weeding produced highest grain yield, while weedy check with high unfilled grains per panicle, less panicle number, and highest density and dry weight of weed had less grain yield. Among the mentioned traits, fertile tillers and panicle number had the highest correlation with grain yield. Unfilled grain number per panicle, density and dry weight of weed, had negative and significant correlation with grain yield. | ||
