EFFECT OF BIOSTIMULATOR ON YIELD COMPONENTS AND CRUDE PROTEIN CONTENT OF THE POPULATION OF WHITE LUPINE (Lupinus albus L.)

The white lupine population tested in the experiment had a high alkaloid content and is not suitable for animal and human consumption, but can be grown for green manure. According to the soil, lupins are not demanding. The seeds of the autochthonous population of white lupine were used, taken from the gene bank of the Institute of Genetic Resources, University of Banja Luka. White lupine seeds were treated before sowing with the microbiological biostimulator, fertilizer containing: nitrogen fixers - bacteria that perform the process of nitrogen fixation; phosphomineralizators - bacteria that break down organic phosphorus compounds (which make up 50-80 % of phosphorus in the soil) and convert them into an accessible form (P2O5) and growth regulators - auxins, which contains indole-3 acetic acid.
