On the results of three years fields experiment carried out during the 2007–2009 periods in the Research Institute of Mountain Stockbreeding and Agriculture in Troyan an analysis of the economic and ecologic effect of leaf organic fertilized mixed cereal-legumes stand of maize and white lupine is done. On the basis of experimental scheme tested it is estimated that variant of dabble treatment of the stand with 4 l/ha BioLIFЕ has the highest economic effect expressed by net income of 99 lеvs/ha and additional effect from this technological choice on value of 60 lеvs/ha. Application of BioLIFЕ in doses of 2 l/ha decreace net income compare to controle by 24 l/ha and this dose is not recommended because added production can not compensate additional expenses done. Application of BioLIFЕ 3 l/ha increase net income obtained by12 lеvs/ha. It definitely transforms the organic fertilization of maize-white lupine mixtures by 3 and 4 l/ha BioLIFЕ into the economically advisable technological decision for the practice. Besides of economic, it is available some ecological effect of organic leaf BioLIFЕ fertilization reflecting in lower weed invasion of the stand. Figured in this way, ecologic efficiency of maize-white lupine mixture increase by 2.64 to about 5 percentage points as much respectively as the decrease of the percentageandrsquo;s weeds presence in the stand. The most practically valued variant is the one including organic fertilization in dose of 4 l/ha which economize 24.11 levs on every hectare weed controls expenses.
