اثر عصاره آبی چریش در مقایسه با باوستین جهت کنترل پژمردگی فوزاریومی نخود

نویسندگان

چکیده

تحقیقات مزرعه‌ای جهت تعیین اثر چریش (عصاره آبی بذر چریش به نسبت 40 میلی‌لیتر در لیتر و وانگارد به نسبت 5 میلی‌لیتر در لیتر) در مقایسه با قارچ‌کش باوستین به نسبت 5/1 گرم در لیتر علیه قارچ پژمردگی نخود (Fusarium oxysporum f.sp. ciceri) صورت پذیرفت. قارچ‌کش باوستین در این تحقیق بیشترین تأثیر را در کنترل قارچ پژمردگی مورد مطالعه داشت. بیشترین ارتفاع گیاه مورد مطالعه به ترتیب مربوط به تیمارهای وانگارد و عصاره آبی چریش گزارش گردید. همچنین، بیشترین پیله‌های جمع‌آوری شده از گیاهان تیمار یافته توسط وانگارد به دست آمد. بالاترین مقدار تولید از تیمارهای باوستین که در زمان‌های 30، 50 و 70 روز بعد از کشت تیمار شده بودند، گزارش گردید، اما بیشترین نسبت سود به هزینه، زمانی گزارش شد که از عصاره آبی بذر چریش 70 روز بعد از کشت استفاده گردید که در مقایسه با بقیه تیمارها از نظر اقتصادی حائز اهمیت بود.

چکیده [English]

A field trial was conducted to find out the efficacy of neem based [neem seed water extracts (NSWE) @ 40 ml/lit and Vanguard @ 5 ml/lit], comparison with bavistin @ 1.5 g/lit, against the Fusarium wilt of chickpea (Fusarium oxysporum f.sp. ciceri). Bavistin proved to be the most effective against the Fusarium wilt between these treatments. Maximum plant height was recorded in case of plot treated with Vanguard followed by seed water extract. Maximum number of pods was collected from plots sprayed with Vanguard. Highest grain yield was obtained due to bavistin, applied at 30, 50 and 70 days after sowing (DAS) but the benefit/cost ratio was highest (3.03:1) in one spray of NSWE, applied at 70 DAS which was more economical than other treatments.
