The aim of this study was to determine the quality of flour, dough and bread made from the grain of winter wheat grown in a continuous cropping system or after oil plants (winter rapeseed, spring rapeseed, white mustard, brown mustard) in production systems of different intensity. The above products, obtained from wheat grain harvested in three growing seasons (2006/2007, 2007/2008, 2008/2009), were analyzed to determine the whiteness, ash content and water absorption capacity of flour, the development time, stability, softening, resistance, extensibility and energy of dough, and the baking volume and yield of bread. The grain of winter wheat grown in a continuous cropping system produced whiter flour with a lower ash content than the grain of winter wheat plants grown after oil plants. The intensification of wheat grain production contributed to flour darkening and a decrease in flour ash content. Monoculture had no adverse effects on the water absorption capacity of flour, the development time, stability or softening of dough. Intensification of production improved water absorption of flour, the development time, stability and softening of dough. The extensibility and energy of dough made from flour obtained from wheat grown in a continuous cropping system were substantially lower, compared with wheat grown after winter rapeseed. Intensification of production also improved dough extensibility and energy. The resistance of dough made from wheat grain produced under medium-input technology was significantly lower, compared with grain produced under low-input technology. Intensification of wheat grain production contributed to a greater increase in the yield of bread made from winter wheat grown after oil plants (primarily winter rapeseed and brown mustard), compared with monoculture.
