The residual effect of presowing soaking seeds in solutions of commercial preparations containing GA₃ and IAA on the growth, development and yield of amaranth of the cultivar Rawa (Amaranthus cruentus L.) was assessed over 2010-2012. It was found that plants grown from treated seeds showed much more abundant growth than the control plants. This activity will be continued also in later developmental phases, although it not always contributed to an increase in plant yield. It appeared that conditioning did not mobilize seeds for more numerous emergences as had been expected when taking up the study. During the growth season the field crop remained under a strong influence of unfavourable weather conditions. Difficulties in obtaining satisfactory density after emergences as well as rainy and windy weather during harvest pose a threat to success in growing amaranth in field.

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.
