| Abstract | The publication contains research materials aimed at improving the elements of technology for growing cassette planting material of strawberry. They are related to the selection of the optimal composition of the substrate for rosettes rooting and increasing the yield of high-quality seedlings by improving the substrate for runners rooting with substances of a biological nature in the conditions of the Right-Bank Forest-Steppe of Ukraine. In order to establish the efficiency of the applied substrate compositions, a control variant with a ready-made peat mixture for strawberry rosettes rooting was included in the experiment scheme. Variants with two types of substrate were accepted as experimental – one with Biohumus adding, and the other one with additional treatment with Trichodermin. Establishing the efficiency of these agricultural measures was carried out on two strawberry varieties - Dukat and Malvina. It was experimentally confirmed that better rosettes rooting with increased growth rates of seedlings was achieved by saturating the substrate peat mixture with Biohumus and Trichodermin. Nutritional and phytosanitary properties of the substrate for strawberry rosettes rooting were improved by filling the peat mixture with Biohumus and Trichodermin. Such biologization of the substrate increased rosettes rooting by 9 % and their leaves density by 25 %. The growth of stem part of strawberry seedlings was more intensive when adding Biohumus and Trichodermin to the peat mixture, which led to the increase in the diameter and the number of stolons by 30 %. Better formation of the root system occurred in the biologically filled peat mixture with Biohumus and Trichodermin. Such a substrate contributed to the improvement of quality indicators of seedlings which increased its market value by 15 %. | ||
