Abstract
A significant increase in grain yield was observed following soil fertilization with nitrogen up to the level of 90 kg·ha-1, independently of foliar fertilization. Among the examined variants of foliar fertilization on average, the significantly highest grain yield was obtained in the objects in which nitrogen and magnesium were administered in parallel. Within the entire range of nitrogen doses administered to soil, a moderately significant increase was noted in total protein content, to the level of 90 kg N·ha-1 a moderately increased content of wet gluten, sedimentation ratio and bread volume were recorded and following application of 60 kg N·ha-1 an increase in water absorbability of flour was observed. Independently of the soil fertilization with nitrogen, the most favourable of the studied variants of foliar fertilization for principal parameters of baking value proved to be a parallel application of nitrogen and magnesium or administration of nitrogen only.
