Vinyukov O. Agrobiological features of increasing the productivity of spring cereal crops in the eastern part of the northern Steppes of Ukraine

Object of study - the processes of growth, development, yield formation and grain quality of spring barley and wheat depending on the application of organic and mineral fertilizers, growth regulators and biopreparations in the eastern part of the northern Steppe of Ukraine. Purpose - definition of agrobiological features of increasing the productivity of spring spiked cereals by improving existing and developing new efficient methods improve adaptability of spring barley and wheat plants. Methods – field; laboratory; measuring and weighing; calculating and comparative; mathematical-statistical. Results improved existing and developed new agrobiological techniques of organic-adaptive technology for growing spring crops that can improve and stabilize the level of grain production in the eastern part of the northern Steppe. Production check and application made in SI “Donetsk state agricultural experimental station of Institute of plant production named after V.Y.Yurjev of NAAS of Ukraine”, and farms of different ownership of Donetsk and Lugansk regions an area of over 180 hectares. Novelty - the first time in the eastern part of the northern Steppe of Ukraine were developed and implemented energy-saving and cost-effective elements of the organic-adaptive technology of cultivation of spring crops and determined their effectiveness. For the first time the effect of sowing making granular biohumus and biofertilizers Aidar seed treatment and crop productivity spring spiked cereals. Found that the use of granular biohumus promotes long-term maintenance and efficient use of productive moisture of the soil. Developed and proposed method of growing root crops for the research, which provides an intact root system of plants for further study. Scientific novelty: was obtained positive effect by using a growth regulators to development and functioning of plant roots, providing better performance and stability of eco-safe products of plant production in the eastern part of the northern Steppe. Sector – agriculture.
