    BLACK CURRANT PRODUCTIVITY FORMATION AS AFFECTED BY THE COMPONENTS OF CULTIVATION TECHNOLOGY
    (УНУС, 2021-10-08) Чернега, Андрій Олегович
    Studied in the experiment were the following components of cultivation technology for black currant: maintaining the soil between rows as black fallow or grassed; maintaining the rows as black fallow, mulched with straw or covered with polyethylene mulch film; foliar dressing in the budding stage with liquid suspended organic fertiliser Riverm at the concentrations of 1, 3 or 5% against the background of complete mineral fertiliser N60P90K90. According to the results of the research, it was found that the best growth and development of black currant plants was for maintaining the soil between rows as black fallow and maintaining the rows mulched with straw. Such practices activate the soil microbiota and facilitate the availability of nutrients to plants. Mulching with straw effectively protects against weeds, prevents damage to plants by tillage tools, and does not prevent rainfall from entering the soil. Accordingly, the best indicators of the maximum number of bunches of black currant (604) fruit number per bush (1315) were obtained in the treatment with maintaining the rows as black fallow and the use of fertiliser N 60P90 K90 (background) + Riverm 5 %. However, the highest fruit weight (1.66−1.74 g) was obtained in the treatment with maintaining the soil between rows as black fallow, the use of fertiliser background N60Р90K90 + Riverm 3 % or Riverm 5 %. In general, the use of mineral fertilisers along with foliar dressing using Riverm increased the fruit yield in the treatment with N60P90K90 + Riverm 3 % under maintaining the rows as black fallow and mulching the rows using the straw up to 13.44 t/ha; for the use of Riverm 5 %, the fruit yield was 13.28 t/ha.
