Plants cover more than 70 % of the global land surface and are among the most important resources on the Earth; their distributions are also intensively and closely related to human activities. Terrestrial plants that can perform photosynthesis are the energy and organic matter providers for almost all ecosystems and are also the main products of the vast majority of terrestrial ecosystems. The plants importance has provided the obtaining of plants information based on various approaches and methods as a constant interest.

The research work contains results of the study on chlorophyll content in currant leaves and its mass, as well as yield of berries depending on the elements of the agricultural technology. It was found that the highest chlorophyll content was after applying N₆₀P₉₀K₉₀ and top dressing with 5 % solution of Riverm fertilizer. That is 0.36% at keeping space between rows as the complete fallow.

Applying mineral fertilizers without top dressing increased this characteristic to 0.24–0.28% depending on the soil consistency near bushes. Top dressing with 1% solution of Riverm fertilizer increased chlorophyll content to 28–40% and application of 2–5% solution increased it to 60–65% depending on the soil consistency near bushes.

A similar tendency is observed in growing currants when there is land resting of the space between rows. However, the chlorophyll content was always significantly lower compared with variants in which space between rows was kept as the complete fallow. The highest chlorophyll content was after applying N60P90K90 and top dressing with 3% solution of Riverm fertilizer. The lowest chlorophyll content was in the variant without fertilizers – 0.19–0.20%.

Studies show that the mass of chlorophyll varied to a large extent and the value of it has changed significantly because of the currant leaves mass. Thus, after keeping the soil between rows as the complete fallow in the variant without fertilizers this characteristic was 3.67 kg/ha in case of the complete fallow near bushes. It was 4.70 kg/ ha after straw mulching and 4.55 kg/ha after mulch planting. Application of N₆₀P₉₀K₉₀ significantly increased this characteristic to 4.83, 6.47 and 5.51 kg/ha respectively or by 32–38% in comparison with the check variant. Top dressing also influenced on the increase in mass of chlorophyll. However, the optimal variant was after application of 3% solution of Riverm fertilizer.

Growing black currants is optimal after applying N₆₀P₉₀K₉₀ and 3 % solution of Riverm fertilizer with keeping space between rows as the complete fallow and straw mulching or mulch planting of bushes.
