It’s established, that most economically used a moisture hybrids Nadiinyi; Zaporizhs’kiy 28; Sava at sowing term 10–13.05. The factor of water consumption has made accordingly 928, 971 і 910 m³/t. At early sowing (18–22.04) the given parameter has increased for 7–8 %. The greatest productivity of hybrids Nadiinyi and Sava has been received at sowing in the second term (28.04–3.05)– 3,25 і 3,31 t per ha. The hybrid Zaporiz’kiy 28 has generated the greatest productivity at sowing in the first term – 3,06 t per ha.

 The article presents the results of the research into the influence of herbicides Granstar 75 (10; 15; 20 и 25 g/ha) and  2,4-DA  500 (1,0 l/ha) applied separately and in combination with plant growth regulator Emistim C on the development of certain ecological-trophic groups of microorganisms in rhizosphere of spring barley. It has been established that nitrifiers and bacteria of the type Azotobacter showthe greatest susceptibility to the impact of investigated herbicides. At the same time under the application of herbicides Granstar 75 and 2,4 DA 500 in mixtures with plant growth regulators Emistim C the negative impact on the development of these bacteria groups decreased. In this case there was the tendency to the increase of the total number of other bacteria groups in the rhizosphere of spring barley.
