Abstract

The paper presents the results of research on the effectiveness of using new plant growth regulators (PGRs) of carbamates and oxamates series on daikon when treating seed material. The effect of growth regulators on seed quality, growth, and yield of daikon (Raphanus sativus L. subsp. acanthiformis Stanken.) of Sasha variety was studied. The research was conducted in laboratory-field conditions from 2022 to 2023 at the Educational Scientific and Production Center for Horticulture and Vegetable Growing named after V.I. Edelstein. In both laboratory and field experiments, the seed material was treated once, followed by plant development using classical technology. All treatments applied had a stimulating effect on seed germination and showed statistically significant differences compared to the control variant. Treatment of seed material with growth regulators of the carbamate series had a significant effect on the size of the assimilation apparatus. The maximum root crop weight was recorded in the variant with the Kartolin-2 preparation, with a difference compared to the control variant of 15%. The obtained data over two years on average showed an increase in yield by 9% and 12% in variants treated with Oxamate and Kartolin-2 preparations.
