Abstract: The article presents the results of studies on the rooting of tall blueberry cuttings conducted in 2022–2024 in the foothill zone of the KBR (LLC “Yug Agro”). Layering, when in contact with a wet peat substrate, is capable of rooting directly in the field. The advantage of this method of reproduction is its simplicity, which does not require the use of expensive technological elements, a high percentage of rooting, as well as the absence of the need for additional cultivation for planting in a permanent place. The purpose of the study – is to optimize the method of propagation of tall blueberries by layering in the conditions of the foothill zone of Kabardino-Balkaria. Research methods. The furrowing of the bark of the part of the shoot buried in the ground was carried out with a knife with teeth. In variants with stimulation of root formation with Phytactive Extra Plus, the gel was applied to the buried part of the shoot after furrowing (or without it) with a brush. Each experimental version was laid and accounted for in three repetitions of 100 accounting layers in each repetition. Research results. It was found that furrowing the bark and subsequent treatment of this area with Phytactive Extra Plus gel before the shoots are sunk into the ground ensures the rooting of 81% of the layers. At the same time, the roots are strong, white, well-branched, and penetrate into the soil by an average of 16 cm. This ensures that the planting material is suitable for planting in a permanent place without additional regrowth during one growing season.
