Effect of Different Sowing Rates and Nitrogen Levels on Grain Yield, Yield Components and Some Quality Traits of Triticale

Zeki Mut, Ismail Sezer and Ali Gulumser    

Abstract: The study was carried out to determine the effects of nitrogen level (0, 60 120, 180 kg ha- 1), sowing rate (200, 350, 500, 650 seed m- 2) on grain yield, yield components and some quality traits of two triticale cultivars under rainfed conditions in Samsun, Turkey, in the 2001-02 and 2002-03. Increasing nitrogen applications increased grain yield, plant height, number of ear m- 2, number of kernel ear- 1, thousand-grain weight, test weight and grain protein content. Plots treated with 500 number seed m- 2 recorded maximum grain yield. This study indicated that sowing rate should be 500 number seed per square meter and nitrogen dose should be between 120 and 180 kg ha- 1 to obtain high grain yield from triticale in Samsun located in the middle Blacksea region and similar ecological conditions.
