چکیده

هدف از این تحقیق، مقایسه‌ی سه نوع کارنده گندم در تولید گندم در اراضی شور منطقه مورد مطالعه بود. پژوهش حاضر به‌صورت طرح آزمایشی بلوک کامل تصادفی در سه تکرار در سال زراعی 1400-1399 در اراضی کشاورزی کشت گندم در منطقه شادگان استان خوزستان اجرا شد. تیمارهای آزمایشی شامل سه نوع کارنده‌ی گندم (1- کارنده‌ی کشت مسطح با دستگاه کارنده خطی کار 2- کارنده‌ی کشت روی پشته 3- کارنده‌ی کشت کف جوی با دستگاه کارنده کف کار) بود که بر روی گندم نان رقم چمران 2 اعمال شد.نتایج به‌دست‌آمده حاکی از تأثیرپذیری صفات مورد بررسی از روش‌های مختلف کاشت بود. بر اساس نتایج مقایسه میانگین مشاهده شد که بیشترین تعداد بذور سبز شده با میانگین 400 بذر در واحد سطح مربوط به روش کاشت مسطح با خطی کار بود که از این نظر برتری معنی‌داری نسبت به سایر روش‌های کاشت داشت. در بین اجزای عملکرد دانه مشاهده شد که بیشترین وزن هزار دانه مربوط به روش کاشت کف جوی با میانگین 34 گرم و کمترین وزن هزار دانه با میانگین 28 گرم مربوط به روش کاشت روی پشته بود. از نظر عملکرد دانه نیز مشاهده شد که بیشترین عملکرد دانه با میانگین 2273 کیلوگرم در هکتار مربوط به روش کاشت کف جوی بود. مقایسه میانگین صفات نشان داد که بیشترین میزان عمق کاشت مربوط به کاشت روی پشته با میانگین 7/42 میلی‌متر بود که از این نظر برتری آماری معنی‌داری نسبت به دو تیمار دیگر داشت. ب

چکیده [English]

The aim of this study was to compare three types of wheat planters in wheat production in saline lands of the study area.This study was conducted as a randomized complete block design with three replications in the crop year 2020-20211400 in agricultural lands of wheat cultivation in Shadegan region of Khuzestan province. Experimental treatments included three types of wheat cultivators (1- flat planter with grain drill 2- planter on beds3- grain drill-furrower) which were applied on bread wheat of Chamran 2 cultivar.
The obtained results showed that the studied traits were affected by different planting methods. Based on the average comparison results, it was observed that the highest number of sprouted seeds with an average of 400 seeds per unit area was related to the flat sowing method with linear work, which had a significant advantage over other sowing methods. Among the grain yield components, it was observed that the highest 1000-seed weight was related to atmospheric floor planting method with an average of 34 grams and the lowest 1000-seed weight with an average of 28 grams was related to ridge planting method. In terms of grain yield, it was observed that the highest grain yield with an average of 2273 kg / ha was related to atmospheric floor planting method. Comparison of mean traits showed that the highest planting depth was related to planting on the ridge with an average of 42.7 mm, which in this regard had a statistically significant advantage over the other two treatments.
