Seed productivity and viability of weed seeds in various soil types
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45The results of long-term field experiments on two types of soils (chernozem and kastanozems) are presented. The indicators of average seed productivity of more than 50 species of weeds growing in these soils are presented. The duration of the viability of seeds planted in a 0–30 cm soil layer, the quality of seeds during their layer-by-layer placement in the soil, on its surface and during storage in a dry warehouse is indicated. It was revealed that early spring and wintering weeds in chernozem soils had the highest seed productivity (more than 50 thousand seeds per plant).
