In this article, we analyze the variability of aboveground dry plant biomass and yield of aboveground phytomass in Trifolium pratense L. and Trifolium repens L. under different growing conditions. The studied species are valuable melliferous, fodder and medicinal plants, which accumulate ascorbic acid, carotenoids, higher fatty acids, glycosides, phenols, flavonoids and other substances. During the growing seasons 2018-2020, we studied 15 natural coenopopulations of T. pratense and T. repens, distributed in the southern taiga, subtaiga, broad-leaf and forest-steppe landscape subzones within the Republic of Tatarstan, Russia. The yield of aboveground dry phytomass in the coenopopulations of T. pratense and T. repens noticeably varied: 59-622 kg/ha and 20-210 kg/ha, respectively. The high yield of dry aboveground phytomass in T. pratense (434-622 kg/ha) and T. repens (178-210 kg/ha) is observed in the subzone of broad-leaf forests, which is characterized by light gray and gray forest soils, as well as the highest precipitation per year, 500-540 mm. At the same time, a significant positive correlation (R=0.63; p<0.05) was revealed between the dry aboveground plant biomass and its yield in T. pratense, and a high significant positive correlation was determined between these parameters in T. repens (R=0.87; p<0.05). The conditions of the broad-leaf forest subzone within the Republic of Tatarstan are the most favorable for the accumulation of aboveground phytomass in T. pratense and T. repens. Therefore, the territories within this zone can be recommended for the collection and procurement of herbal medicinal raw materials of these species.
