The effect of some methods for the presowing improvement of seeds of amaranth of the cultivar Rawa (Amaranthus cruentus L.) on their sowing value was assessed in laboratory conditions. The results of seed soaking in solutions of commercial preparations were examined, where the active substance was synthetic growth regulators – auxin and giberelin. The experiments were conducted in 2010-2012 at the time preceding sowing seeds in the field (in April each year). It was indicated that under laboratory conditions germination energy and capacity of amaranth seeds of the cultivar Rawa depends to a much larger degree on germination temperature than on choosing the preparation in which sowing seeds are soaked, and germination capacity at 25ºC can be regarded as quite satisfactory in all the treatments. Soaking amaranth seeds in solutions of bioregulators turned up to be effective, although only in definite conditions.
