Changes of quality properties of spring wheat grain resulting from some agrotechnical factors

Technological value of grain of two cultivars of spring wheat (cv. Broma and cv. Torka), cultured in years 2002-2004 with two levels of N-fertilization applied, was tested. Yield, thousand kernel weight, bulk density, protein content, wet gluten content, gluten index and failing number were estimated. Influence of weather conditions in each of vegetation period on quality of grain was analysed. Results showed higher yield of grain of Broma cultivar. Significant differences between years of experiment were observed. Higher level of N-fertilization caused increase of protein content in grain of both cultivars; higher protein content and gluten index for Torka was observed. Weather conditions in 2003 caused decrease of grain quality.
