چکیده مقاله :
مدیریت تلفیقی تغذیه گیاه، راهکاری مناسب برای افزایش بهره‌وری گیاهان زراعی و بهبود محیط زیست به شمار می رود. به منظور بررسی اثر کاربرد باکتری‌های محرک رشد همراه با سطوح مختلف ورمی‌کمپوست بر عملکرد کمّی و کیفی کلزا، آزمایشی در سال زراعی 94-1393 به صورت مزرعه‌ای به اجرا درآمد. تیمارهای آزمایش شامل تلقیح و عدم تلقیح (شاهد) بذرهای کلزا با باکتری‌های محرک رشد و کاربرد سطوح مختلف ورمی‌کمپوست به مقدار صفر (شاهد)، 4، 8 و 12 تن در هکتار بودند. نتایج نشان داد که اثرات ساده و برهم‌کنش کاربرد ورمی‌کمپوست و باکتری‌های محرک رشد بر صفات کمّی و کیفی کلزا معنی‌دار بودند. به طوری که با افزایش مقدار کاربرد ورمی‌کمپوست از ۴ تا ۱۲ تن در هکتار، افزایش معنی‌داری در صفات مورد بررسی نسبت به شاهد مشاهده شد. هم چنین، تلقیح بذرها با باکتری‌های محرک رشد نیز باعث افزایش مقدار صفات اندازه‌گیری شده نسبت به شاهد گردید. کاربرد 12 تن ورمی‌کمپوست در هکتار به همراه باکتری‌های محرک رشد ، باعث افزایش تعداد خورجین در بوته، وزن هزار دانه، عملکرد بیولوژیک، عملکرد دانه، شاخص برداشت و عملکرد روغن به ترتیب به میزان 28.63 عدد، 4.68 گرم، 2.10785 کیلوگرم، 3484.2 کیلوگرم، 38.02% و 1795.93 کیلوگرم در هکتار نسبت به شاهد شد. کاربرد 12 تن ورمی‌کمپوست در هکتار به همراه باکتری‌های محرک رشد در سه صفت عملکرد دانه، شاخص برداشت و عملکرد روغن منجر به افزایش به ترتیب 83، 45 و 43 درصد نسبت به شاهد گردید. بنابراین، در خاک‌هایی با کمبود مواد آلی، کاربرد هم‌زمان ورمی‌کمپوست و باکتری‌های محرک رشد می‌تواند سبب افزایش معنی‌داری در عملکرد کمی و کیفی کلزا شود.
Integrated plant nutrition management is a good method to increase the productivity of crops and improve the environment. To evaluate the effects of using growth promoting bacteria and different levels of vermicompost on quantitative and qualitative yield of rapeseed (Brassica napus L.), a field experiment was conducted in 2014-2015. The treatments consisted of inoculation and non-inoculation of canola seeds with growth promoting bacteria and application of different levels of vermicompost (0, 4, 8 and 12 t.ha-1). The results showed that simple effects and interaction of vermicompost and growth promoting bacteria on quantitative and qualitative traits of canola were significant. That is to say with increasing the application of vermicompost from 4 to 12 tons per hectare, a significant increase was observed in the traits under study as compared to the control. Inoculation of seeds with growth promoting bacteria also increased the amount of measured traits as compared to the control. The application of 12 tons of vermicompost per hectare, along with growth promoting bacteria, resulted in an increase in the number of pods per plant, 1000-seed weight, biological yield, grain yield, harvest index and oil yield, (28.63, 4.68 g, 10785.2 kg, 3484.2 kg, 38.02% and 1795.93 kg.ha-1, respectively, as compared with control). Application of 12 t.ha-1 of vermicompost per hectare along with growth promoting bacteria resulted in grain yield, harvest index and oil yield increase by 83%, 45% and 43%, respectively, as compared with control. Therefore, in soils with low organic matter content, simultaneous application of vermicompost and growth promoters bacteria can improve the quality and quantity of rapeseed yield .
