| Abstract | The purpose. To reveal the peculiarities of the passage of phenological phases of growth and development of white and black mustard plants depending on the ecotype of varieties and growing conditions. Methods. Field observation of the growth and development of plants, the passage of phenological phases and the conditions of the external environment, calculation and comparison. The results. It was established that the duration of the mustard growing season depended on the weather conditions during its cultivation and varietal characteristics. On average, over three years, the duration of the growing season of the varieties in the conditions of the Right Bank Forest Steppe was 65 days, and it varied by variety from 62 days (the Etalon variety) to 64 days – the Pidpecheretska variety. The longest vegetation period (68–73 days) of all varieties was in 2022, the shortest (58 days) in 2021. In 2023, there was a slight change in the length of the vegetation period by variety (60–65 days). Among the investigated varieties, the longest vegetation period was characterized by the Oslava variety – 73 days, the Pidpecheretska variety – 72 days, and the Tsarivna Pivnochi variety – 71 days. In Etalon and Ariadna varieties, it was shorter and amounted to 68 and 66 days, respectively. Conclusions. The onset and passing of the phenological phases of growth and development of black and white mustard plants and the duration of its growing season depend on the beginning of the growing season, weather conditions during the growing season, and varietal characteristics. A direct linear relationship was established between the amount of precipitation and the appearance of full seedlings (r = 0.97). Depending on the varietal characteristics, minor deviations of 1–5 days were recorded in the passage of the phenological phases of growth and development of black and white mustard plants. | ||
