Now the wide spectrum of plants growth-regulating preparations of biological and synthetic
origin appeared in the agrarian market of Ukraine. However, efficiency of their applications in
growing of grain-crops remains weakly studied. In publicity aims, often companies-producers
not always give objective and reliable information about application of such preparations in
concrete soil-climatic conditions and not take into account the features of growing of separate
agricultural plants.
In the Institute of Agriculture Crimea of National Academy of Agriculture Sciences of
Ukraine efficiency of the pre-sowing treatment of grain-crops seeds by the different of plant
growth-regulating preparations (such as Mars, Agate-25K and so on) was studied in the field
experiments in the zone of Steppe of Ukraine during 4 years (2007-2010). It is established,
that this agrotechnological method allows to increase the productivity of winter wheat by
0.23-0.29 t.ha -1 , the net income by 28.2-37.5 $/ha at recoupment of expenses - 0.4-0.5 $. The
application this preparations on a winter barley allows to increase the seeds productivity by
0.24-0.34 t.ha -1 , the net income by 24.6-38.1 $/ha at recoupment of expenses – 0.2-0.4 $.
