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.
