| Abstract | Purpose. To determine the formation of growth indicators of different willow species depending on the elements of cultivation technology. Methods. Laboratory, mathematical and statistical. Results. It was established that when growing willow of the cv. Panfylska, shoot height was the lowest during the first assessment – 42–75 cm depending on the research year. The tallest plants at the end of the growing season reached 133–182 cm. The application of fertilizer increased plant height by 13–34% depending on the storage method of willow cuttings. At the same time, the significance of the storage method decreased when fertilizer was applied. It should be noted that when willow was grown without fertilizer, the effect of the storage method varied depending on the research year. Thus, in 2023, the best results were obtained when cuttings were stored in polyethylene bags in a storage facility with the cut surfaces treated with lime. However, in 2024 and 2025, the storage method of willow cuttings had no such significant effect. The plant height of willow cv. Zbruch was 6–12% lower compared to cv. Panfylska. The number of shoots at the beginning of the assessments either did not differ or was the same as at the end of the growing period. Under fertilizer application, the number of shoots in cv. Panfylska at the beginning of assessments ranged from 3.4 to 4.5 shoots per plant. At the end of the growing season, the number of shoots varied from 3.8 to 6.7 shoots per plant depending on the research year. When willow was grown without fertilizer, the number of shoots at the beginning of the assessments ranged from 2.5 to 3.7 shoots per plant, and at the end of the season—from 2.6 to 5.4 shoots per plant depending on the year. In the cv. Zbruch, the number of shoots also changed significantly depending on fertilizer application. At the beginning of assessments, this indicator ranged from 2.5 to 6.4 shoots per plant, and at the end of the growing season—from 3.4 to 8.1 shoots per plant. In unfertilized plots, the number of shoots at the beginning of May was 1.8–5.7 shoots per plant, and at the end of the season – 2.4–7.9 shoots per plant depending on the year. The number of shoots in fertilized plots was 3.0–42% higher compared to unfertilized plots. Conclusions. The number of shoots at the beginning of assessments either did not differ or corresponded to the number at the end of the growing period. Under fertilizer application, the number of shoots in cv. Panfylska at the beginning of assessments ranged from 3.4 to 4.5 shoots per plant, and from 3.8 to 6.7 shoots per plant at the end depending on the year. Without fertilizer, the number of shoots ranged from 2.5 to 3.7 at the beginning and from 2.6 to 5.4 shoots per plant at the end. In cv. Zbruch, the number of shoots varied significantly under fertilizer application: 2.5–6.4 at the beginning and 3.4–8.1 at the end of the growing season. | ||
