چکیده | ||
برای تعیین عرض مناسب جویچهسازها در خطیکار کفکار و اثر آن بر عملکرد گندم، این پژوهش در قالب طرح آماری بلوک کامل تصادفی با چهار تیمار و چهار تکرار اجرا شد. تیمارها شامل کاشت گندم با دستگاه خطیکار کفکار با عرض جویچهسازهای 60 ، 75 و 100 سانتیمتر و کاشت گندم روی پشته با خطیکار مرسوم با عرض جویچهساز 60 سانتیمتر (شاهد) بود. پارامترهای شوری خاک (EC)، درصد سبز گندم، وزن هزاردانه و عملکرد محصول اندازهگیری شد. نتایج نشان داد که استفاده از خطیکار کفکار بر توزیع شوری در پروفیل خاک، درصد سبز و عملکرد گندم موثر است. شوری خاک در روی پشته و کنار پشته نسبت به کف جوی به ترتیب 7/50 و 1/17 درصد افزایش داشته است. خطیکار کفکار با عرض جویچهسازهای 75 سانتیمتری نسبت به روش کاشت گندم روی پشته، باعث افزایش درصد سبز گندم (1/43 درصد)، وزن هزاردانه (9/5 درصد) و عملکرد گندم (3/39 درصد) شد. | ||

چکیده [English] | ||
This study was a randomized complete block experimental design with four treatments and four replications to determine the suitable furrows width for in-furrow grain drill and also wheat yield. Treatments were planting wheat by in-furrow grain drill with furrows width of 60, 75 and 100 cm and planting wheat on raised bed by conventional grain drill with furrow width of 60 cm (control). In this project, the effect of in-furrow grain drill on EC, seeds germination percent, 1000 seeds weight and crop yield were studied. Results indicated that in-furrow grain drill affected distribution of salinity (EC) in soil profile, seeds germination percent and wheat yield. The salt concentration at the top-center of beds and at the sides of the beds increased by 50.7% and 17.1% compare to mid-furrow, respectively. In-furrow grain drill with furrow width of 75 cm increased seeds germination (43.1%), 1000 seeds weight (5.9%) and crop yield (39.3%) compare to planting wheat on raised bed. | ||
