THE YIELD OF WINTER WHEAT DEPENDING ON THE METHODS OF BASIC TILLAGE AND GROWTH REGULATORS IN THE CONDITIONS OF FOOTHILL DAGESTAN
In the conditions of the Foothill province of Dagestan, in order to improve the elements of winter wheat cultivation technology, field experiments were laid in the period from 2021 to 2023. The following wheat varieties were studied: Bezostaya 1 (standard), Tanya, Thunder, Power. From agrotechnical techniques, against the background of pre-sowing seed treatment with growth regulators Albit and Siliplant, we studied the options of experience: dump processing, non-dump processing. As a result, it was found that the highest grain yield of wheat varieties was formed during dump tillage. So, on average, according to the variants with growth regulators, the yield of the Bezostaya 1 variety was 3.32 t/ha. The highest indicator, at the level of 4.18 t/ha, was recorded on the crops of the Grom variety, the excess compared to the standard was 25.9%. Sufficiently high yield data were also noted in the Sila variety, on average 3.78 t/ha, which is 13.8% more than the Bezostaya 1 variety. In addition, experimental data indicated the effectiveness of the use of growth regulators. So, on average for varieties, in the variant with Albit growth regulators, grain yield was 3.91 t/ha, and against the background of the Siliplant regulator - 3.78 t/ha. The data of the control variant (water treatment) were lower than these variants by 11.1 - 7.4%. Approximately the same dynamics was also observed in the variant with non-tillage tillage. Comparative data of winter wheat varieties on the formation of yields, depending on the methods of tillage used, showed that according to the options with growth regulators, they were higher during dump processing than non-dump processing - by 8.6, 8.1 and 8.0%, respectively.
