چکیده

در این تحقیق تاثیر مدیریت بقایای گیاهی و زمان انجام پی آب در قالب طرح آماری اسپیلیت بلوک و در سه تکرار بر عملکرد گندم، میزان آب مصرفی و هزینه و درآمد هر تیمار بررسی شد. تیمار اصلی، مدیریت بقایای گیاهی شامل سوزاندن بقایای گیاهی (B)، خارج کردن قسمت عمده بقایای گیاهی و استفاده از ساقه خردکردن (R)، و خارج کردن قسمت عمده بقایای گیاهی و استفاده از ساقه خردکردن و شخم با گاوآهن برگردان دار (RP) بود. تیمار فرعی زمان انجام پی آب شامل آبیاری 7 روز پس از کاشت (I7)، آبیاری 14 روز پس از کاشت (I14)، و آبیاری 21 روز پس از کاشت (I21)  بود. نتایج نشان داد که مناسب ترین تیمار با توجه به بررسی های اقتصادی انجام شده تیمار RI21 بود که نسبت به تیمار شاهد حدود 1220000 ریال در هر هکتار افزایش سوددهی داشته است.

چکیده [English]

A split-block experiment of three replications was employed to study the effect of residue management and post-irrigation regimes on wheat yield, water use and cost and benefit of treatments. Three levels of residue management including burning entire crop residue (B), removing part of crop residue and using stalk shredder (R), removing part of crop residue, using stalk shredder and moldboard ploughing (RP), were considered as main plots. Three levels post-irrigation regimes including irrigating 7 days after planting (I7), irrigating 14 days after planting (I14), and irrigating 21 days after planting (I21) were considered as sub plots. Results of economical analysis indicated that proper treatment was RI21 that increased profitability by 1220000 Rial/ha relative to the control treatment.
