Abstract
Field experiments were conducted in 2019–2020 in the cultivation of winter wheat of the KWS Ozon variety. The growth retardant trinexapac ethyl + prohexadione calcium (TE + Pca) and its mixtures with adjuvants and citric acid were used in the BBCH 32/33 phase of winter wheat. The effectiveness of the growth retardant depended on the dose of the preparation, the type of adjuvant, and weather conditions. Lower average daily air temperatures favored the effectiveness of the full dose of the preparation. Different relationships were noted in variants in which TE + Pca was used at a reduced dose together with adjuvants and citric acid. Among the tested variants, the greatest shortening of the canopy was achieved after the use of a mixture of the retardant and the AS (ammonium salts of polybasic acids) adjuvant compared to the control and plots treated with a lower dose of the preparation. The method of application of the tested agent in most combinations did not have a significant impact on the yield and quality of the obtained grain in both years of the study. In the case of the mixture of TE + Pca retardant with AS adjuvant, inconclusive results were obtained. In 2019, a significant reduction in the weight of one thousand seeds was recorded compared to the control variant.
