| Summary: | One of the most promising agricultural crops is red clover, which can be used as forage for farm animals and for energy purposes. In addition, this crop plays an important agri-environmental role as it helps to improve soil fertility. The aim of this work is to establish the dependence of the production processes of red clover, as the main component of legume-grass agrophytocoenosis, on the use of lime, inoculant, growth enhancers, and phosphorus-potassium fertilizer. The study was conducted in the conditions of a stationary field experiment in the Western Forest-Steppe of Ukraine. Determination of the main parameters of red clover crop formation was carried out by theoretical calculations, which are based on the share of red clover in legume-grass, which originated in 2011.
The highest share of red clover in legume-grass was noted in the second and third years of use. The multiplicity of use had the greatest influence on the formation of the assimilation surface of red clover. Three times cutting of grasses stipulated the formation of up to 61 % of leaves. The highest percentage of leaves was recorded when composite organo-mineral fertilizer on the background of phosphorus-potassium fertilizer and liming was used. Liming also had a noticeable effect on the increase in the proportion of red clover leaves. The usage of limestone fertilizers on legume-grass increased the proportion of red clover leaves by 3–4 % in the first cut, 18–22 % in the second, and 5 % in the third, and increased the net productivity photosynthesis of red clover by 33 %. Inoculation of seeds with rhizobophyte on the background of phosphorus-potassium fertilizer and double mowing of grasslands provided the highest indicators of photosynthetic potential (31.8–34.1 million m2/day/ha) of red clover. The reduction of the periods between cuts due to three-time use reduced the photosynthetic potential of each cut, however, as a whole during the growing season, this indicator slightly increased.
Therefore, to make fuller use of the potential of red clover when growing it in a mixture in the meadow agrophytocoenosis, it is advisable to conduct liming of the soil, apply phosphorus-potassium fertilizer and inoculation of seeds with rhizobophyte, and cut the grass twice during the growing season.
