| Abstract | Objective. To determine the optimal parameters for forming tobacco raw material. Methods. Field, laboratory, measuring, calculation-comparative, analytical, and statistical methods. Results. Research findings indicate that the highest yield of raw material was achieved by growing the tobacco variety Temp 321 during the first planting date and Burley 46 during the second planting date. The lowest yield was shown by the Burley 38 variety – 2.40–2.70 t/ha depending on the planting time. Yield varied significantly depending on the year of the research. For instance, in 2018, the highest yield was observed – 4.32–6.24 t/ha, whereas in 2019, it ranged from 1.61 to 3.34 t/ha depending on the variety during the first planting time. It is noteworthy that the second planting time of seedlings resulted in even lower yields. The highest seed yield during the first planting time was recorded for the Burley 9, Ternopilskyi 14, and Virginia 27 varieties – 1.51–2.01 t/ha. For the second planting date, this figure was 1.14–1.36 t/ha, or 32–48% lower. The lowest seed productivity was shown by the Ternopilskyi 7 variety during the first planting time – 1.13 t/ha. During the second planting time, the Ternopilskyi 7, Burley 38, and Temp 321 varieties yielded 0.91–0.93 t/ha. Seed yield varied less significantly depending on the year of research. During the first planting time, the seed yield in 2018 ranged from 1.24 to 2.48 t/ha, in 2019 from 0.99 to 1.90 t/ha, and in 2020 from 1.14 to 2.22 t/ha. During the second planting time, this indicator was lower compared to the first. Conclusions. The highest tobacco yield was achieved by cultivating the Temp 321, Burley 46, Virginia 27, and Ternopilskyi 14 varieties — from 3.06 to 4.53 t/ha. It has been proven that under the agro-climatic conditions of the central part of the Forest-Steppe zone of Ukraine, tobacco plants produce seeds of high sowing quality. The Ternopilskyi 14 and Virginia 27 varieties were the best in terms of seed productivity, with seed yields of 2.34 and 2.88 t/ha, respectively. | ||
