The paper presents the results of research conducted during the years 2015–2020 and the analysis of the influence of changing climatic conditions during the year on plant development, the number of crops obtained from gooseberry, Josta, black currant, red currant and white currant. The average fruit harvest obtained for the studied species varies depending on several factors, especially on the species, variety and changing climatic conditions of the year. Among the studied species, the gooseberry is the most productive, followed by the hybrid Josta, the red currant, the black currant and the white currant. As a result, the analysis of the data obtained regarding the fruit production allowed us to establish that depending on the species, the harvest of gooseberry varied between 7.36-11.9 t/ha, on Josta between 4.7-8.2 t/ha, for black currant – 4.3-8.1 t/ha, red currant – 4.3-8.5 t t/ha and for white currant – 3.7-7.8 t/ha. The crop according to variety increases the harvest on gooseberry by 3.13 %, blackcurrant by 1.49%, red currant by 2.99 %, and the harvest of white currant is not influenced by variety. In the conditions of a favorable year (year 2015), high harvests were obtained for the black currant with 8.1 t/ha; in 2016 year for gooseberry with 11.8 t/ha, Josta – 8.2 t/ha, red currant – 8.5 t/ha, for white currant – 8.2 t/ha. In the conditions of an unfavorable year (year 2020 compared to 2016), the harvest decreased on gooseberry by 36.1%, Josta by 42.7 %, black currant by 46.9 %, red currant by 49.4%, white currant by 52.6 %.
