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

摘要

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.
