The research carried out during three years allow to draw conclusions that use of preparations sapronit, phytostimophos and rhizobakterin with microbe-vegetative interaction at cultivation of Alfalfa Belarusian for sowing on forage not only raises its productivity, but also increases the content of digestible protein in dry matter. Seed processing by the preparation of diazotrophy microorganisms sapronit raises productivity on 12,2 c/hectares (12,4%). Spraying by this preparation of crops in spring plant regrowth also it is effective: the productivity increase makes 13,3 c/hectares of dry matter (13,6%). Application of the combined bacterization (sapronit + phytostimophos, sapronit + phytostimophos + rhizobakterin) provides the greatest efficiency at processing of seeds and not root processing of crops. The productivity increase on 13,5-14,1% at seed processing and spraying of herbage in spring by a binary mix. Use of a threefold mix at the given ways of application of preparations has raised dry matter gathering on 15,0-18,6%. Mixes of studied preparations considerably raise the content of digested protein in lucerne plants: a binary mix at processing of seeds and spraying of a herbage in spring regrowth on 7,3-7,5%; threefold - at all ways of application on 8,0-9,0%. At use of studied preparations by way of processing of seeds or sprayings of plants in spring regrowth the exit of exchange energy, gathering fodder and feed-protein units about 1 hectare of crops essentially increases. The maximum action is rendered thus by a threefold mix of studied preparations. The data obtained as a result of three-year research on application of diazotrophy and phosphate-mobilizing preparations and to their influence on efficiency and quality of lucerne for sowing allow to recommend to include this agroreception in technology of culture cultivation
