e1“The following have a negative impact on product yield: temperature changes in late summer and early autumn, especially on southern slopes, which can make it difficult for plants to overwinter”
e2“thaws in March, causing the formation of an ice crust on the soil surface and damaging the tillering nodes of plants”
e3“The yield monitoring (1998–2023) of cloverothymothy grass stands of 1 year of use within the moraine hill was carried out in order to find patterns in the influence of weather conditions on it”

Other claims from this paper (11)
- Association Average daily temperatures, their amplitude, precipitation and the hydrothermal coefficient together explain about 43% of the variability in grass productivity.
- Association Fluctuations in temperature amplitudes account for 32% of the temporal variability of grass yield.
- Association Herb yield is affected by the variability of growing conditions both in time and in space.
- Association Air temperature changes reduce grass yield in all parts of the landscape except the flat top.
- Association On the flat top, productivity increases with growth of the hydrothermal coefficient.
- Association On the flat top, productivity decreases with increasing air temperatures in the pre-harvest period.
- Association Temperature changes in late summer and early autumn reduce product yield, especially on southern slopes.
- Association Hot days in the pre-harvest period accelerate the ripening of grasses.
- Association Hot days in the pre-harvest period reduce the intensity of biomass accumulation in grasses.
- Association February thaws increase grass yield by promoting moisture accumulation in the soil.
- Recommendation Autumn mowing of young grass, snow retention in meadows and sprinkling of grass on the hottest pre-harvest days are recommended to reduce the negative impact of temperature changes on the grass harvest.
