Study of the influence of the timing of sowing grass mixtures on the quality of lawn in the forest-steppe of Western Siberia

Lawn is one of the main elements of landscaping of any territory, where the effect of fast and high-quality landscaping is fundamental. To solve this issue, many manufacturers offer short-lived but rapidly developing types of herbs (grassland ryegrass) or try to dilute high-quality grass mixtures with them, which subsequently negatively affect the quality of the herbage and require additional costs. In this work, the germination rate, the dynamics of the formation of the density of shoots of the herbage and the decorative coating were studied at different sowing periods, various grass mixtures. As a result, it was found that the lowest rates of shoot formation are formed during the sowing of grass mixtures in the autumn (1.9-2.2 thousand units/m 2 ), and the highest (17.2 – 24.1 thousand units/m 2 ) during the spring sowing period. It has been established that the dynamics of shoot formation strongly depends on the sown grass mixture. Thus, the highest rates in terms of standing density were achieved on single-species meadow bluegrass crops, which, due to their characteristics, formed 100% coverage of the territory at all sowing periods and had a closed-diffusion addition, which means that this grass mixture forms an almost continuous stand resistant to systematic mowing.
