APPLICATION OF ORGANIC ACIDS AND ITS MIXTURES AS A STIMULATOR OF SEED GERMINATION

The intensification of the germination of seed material of different crops is a promising direction for improving agricultural technologies. The use of safe and highly effective germination activators allows to accelerate the biological processes of plant growth, to reveal the productivity potential inherent in each variety. Increasing the rates, such as energy and germination, significantly increase crop yields. The scientific work objective was to expand the range of universal crop growth stimulants that would be able to provide uniform germination, increased energy and the ability to germinate seed material, as well as shorten the period from sowing to seedlings. The use of organic acids is proposed: nicotinic (3-pyridinecarboxylic), folic (pteroylglutamic), succinic (butanedioic) with a given concentration of active substances. This technological solution allows to intensify the processes of seed germination of various crops. The presented organic acids and their solutions are recommended to be used in pre-sowing treatment of seeds by spraying or one-time soaking in aqueous solutions of these acids. The studies were carried out on the base of the scientific and production laboratory for determining the quality of grain and grain products of the Dnepropetrovsk State Agrarian and Economic University. The studied growth stimulants have established themselves as substances with a stable effect and low toxicity. They can be used both in crop production in pre-sowing seed treatment in order to intensify growth, and for the production of germinated grain in the production technologies of alcohol, beer, mono-and polysalt malt extracts in order to obtain malt.
