Among the elements of crop cultivation technologies, mineral fertilization and plant protection
have a decisive effect on the quantity and quality of wheat grain yield. Therefore, learning the
responses of wheat hybrid cultivars introduced into cultivation to the intensity of a cultivation
technology should be considered useful. In 2013-2016, a controlled field experiment was carried
out, the aim of which was to evaluate the responses of winter wheat hybrid cultivars (Hystar,
Hyfi) grown in the low, medium and high input technologies. The growing intensity of a cultivation technology resulted in a significant increase in grain yield and the content of protein, gluten, phosphorus and magnesium, as well as iron, zinc and manganese in grain. Wheat grain
from the high input technology was characterized by a higher proportion of the fractions
of gliadins and glutenins and their subunits, without differentiating the fractions of albumins
and globulins. A lower total precipitation during the grain formation and maturing resulted
in a decrease in the grain yield and an increase in grain quality parameters and the content
of gluten subunits with the exception of ω gliadins. The cultivar Hystar was characterized
by a higher grain yield (by 0.97 t ha-1). The cultivar Hyfi had higher quality parameters with
a more favorable proportion of storage proteins and a higher content of phosphorus, magnesium,
zinc and manganese in grain.
