| به منظور مطالعه تاثیر مقادیر مختلف کود نیتروژن و تعداد نشاء بر عملکرد و اجزای عملکرد دو رقم برنج فجر و شیرودی، آزمایشی مزرعه ای در شهرستان بابل در سال زراعی 1389 اجرا شد. آزمایش به صورت اسپلیت اسپلیت پلات در قالب طرح بلوک های کامل تصادفی در سه تکرار با سه عامل شامل مقادیر کود نیتروژن ) 0، 5/ 57 و 115 کیلوگرم در هکتار( به عنوان عامل اصلی، تعداد نشاء در کپه ) 3، 4و 5 بوته( عامل فرعی و رقم )فجر و شیرودی( به عنوان عامل فرعی فرعی انجام گرفت. نتایج نشان داد که مقادیر مختلف کود نیتروژن بر صفاتی مانند عملکرد شلتوک، شاخص برداشت، تعداد پنجه بارور، تعداد خوشه و عملکرد بیولوژیک اثر معنی داری داشته و بین سطوح مختلف نشاء در همه صفات مورد مطالعه بجز تعداد خوشه، عملکرد شلتوک و عملکرد بیولوژیک تفاوت معنی داری وجود نداشت. مصرف کود نیتروژن به طور معنی داری موجب افزایش عملکرد شلتوک در مقایسه با تیمار شاهد )عدم مصرف کود نیتروژن( شد. اثرات متقابل رقم در مقدار کود نیتروژن نیز برای صفات عملکرد شلتوک و تعداد خوشه معنی دار گردید، بدین صورت که بیشترین مقدار عملکرد در تیمار با مقدار نیتروژن 115 کیلوگرم در هکتار و رقم شیرودی مشاهده شد. در بین صفات مورد مطالعه تعداد پنجه بارور، تعداد خوشه و عملکرد بیولوژیک بیشترین همبستگی را با عملکرد شلتوک داشتند. | ||

| In order to study the effects of nitrogen fertilizer rates and plant number on yield and yield components of two rice cultivars, a field experiment was carried out in Babol city- during 2010. A split-split plot experiment on the basis of randomized complete block design with 3 replications and 3 factors including fertilizer rate (0, 57.5 and 115 kg.ha-1), plant number per hill (3, 4 and 5) as sub plot and cultivars (Fajr and shiroudi) as sub sub plot were used. Results showed the rates of nitrogen fertilizer had significant effect on grain yield, harvest index, fertile tillers number, panicle number and biological yield. Also, different levels of plant number have not significant effects except of panicle number, grain yield and biological yield. With increasing nitrogen fertilizer application, grain yield was increased significantly compared with control treatment (without nitrogen fertilizer application). Interaction effect between nitrogen fertilizer rate and cultivar was significant at 1% probability levels for grain yield and panicle number in which the highest yield was belong to the nitrogen fertilizer rate of 115 kg.ha-1 and Shiroudi cultivar. Among the mentioned traits, fertile tillers number, panicle number and biological yield had the highest correlation with grain yield | ||
