Abstract
The solution to the problem of stabilizing the high-quality wheat grain production is of great urgency. The current study was conducted at the experimental plot of the «North Caucasus FARC» on ordinary medium-loamy, moderately deep, lowhumus blackearth in the unstable moisture area of the Stavropol Territory from 2023 to 2025. The purpose of the study was to characterize the economically valuable traits of new winter wheat varieties bred by the FSBSI «North Caucasus FARC» undergoing the state variety testing and to demonstrate their response to nitrogen top dressing during the heading growth stage. There have been studied two new winter common wheat varieties Taisiya and Aidariya. The varieties were studied according to the Methodology of the State Variety Testing and compared with the standard Grom. For three years of testing the average productivity of the varieties Taisiya and
Aidariya was 8.04 and 8.11 t/ha, that of the standard variety was 6.98 t/ha, the productivity excess over the standard variety was 15.2 and 16.2%. The largest mean productivity increase due to the use of urea was obtained from the standard Grom (0.23 t/ha), the varieties Aidariya and Taisiya produced 0.14 t/ha and 0.07 t/ha, respectively. Foliar nitrogen top dressing significantly increased gluten percentage in the varieties Aidariya and Taisiya by 2.6% and 5.2%, respectively, and by 3.4% in the standard Grom. The new varieties Taisiya, Aidariya, and the standard Grom demonstrated responsiveness to nitrogen top dressing during the heading growth stage, producing better grain according to a range of quality indicators, demonstrating the potential of foliar nitrogen top dressing during the heading growth stage.
