| Abstract | Goal. To determine the economic efficiency of propagating species of the genus Hydrangea L. by cuttings using rooting stimulants. Methods. Field and laboratory studies on the cultivation and propagation of Hydrangea L. species were conducted at Uman National University and the National Dendrological Park ''Sofiyivka'' of the National Academy of Sciences of Ukraine during 2020–2024. Cuttings for vegetative propagation were collected in mid-July from current-year shoots. To promote rooting, stimulate root formation, and enhance plant growth, the rooting agent Heteroauxin Super and the biologically active biostimulant Radifarm + were used. The annual economic efficiency of growing one-year-old hydrangea plants was calculated taking into account the yield of planting material obtained under laboratory conditions and production costs, in accordance with established methodological guidelines for conducting agricultural research. Results. It was found that treatment of green cuttings with the rooting stimulant Radifarm + resulted in the highest annual economic efficiency, amounting to 196.0 UAH. The lowest cost per seedling was observed in the control treatment (6.56 UAH), whereas the highest cost (9.90 UAH) was recorded when green cuttings were treated with the rooting stimulant Radifarm +. In the propagation of hydrangea by green and woody cuttings, the application of the growth stimulant Radifarm+ and heteroauxin improved rooting efficiency, which contributed to obtaining profits from the sale of green cuttings in the range of 3,067.4–3,194.4 UAH and woody cuttings 2,887.4–3,014.4 UAH. According to the analysis of the costs of propagating 100 seedlings, the highest expenses were associated with the use of both rooting stimulants. In particular, the cost of Radifarm+ accounted for 34% and heteroauxin for 26% of the total production costs. The rooting efficiency of hydrangea cuttings propagated from woody cuttings was lower than that of green cuttings, which accordingly affected the economic indicators. With identical costs for hydrangea cultivation, sales revenue in the control treatment was 315 UAH lower, and 180 UAH lower when cuttings were treated with rooting stimulants, compared to propagation by green cuttings. At the same time, treatment of woody cuttings with Radifarm+ and heteroauxin resulted in an increase in profit from sales by 331.0 UAH and 204.0 UAH, respectively, compared to the control. Conclusions. Propagation of hydrangea by green and lignified cuttings treated with the growth regulator Radifarm + and heteroauxin increased rooting efficiency, resulting in higher yields and, consequently, additional profit from the sale of green cuttings (3067.4–3194.4 UAH) and lignified cuttings (2887.4–3014.4 UAH). Treatment of both green and lignified cuttings with the rooting stimulator Radifarm+ proved to be more effective, ensuring a higher rooting percentage and, accordingly, greater profit compared to heteroauxin treatment. | ||
