In soil and climatic conditions of Grodno region of the Republic of Belarus on sod-podzolic sandy loam soils there was studied the efficiency of application of the associative nitrogen fixer Azobacterin for cultivation of winter rape (Brassica napus) of Lider variety. In course of the realized study it was stated that application of the biological preparation against the background of NPK nitrogen fertilizers exercised the positive influence on yielding capacity of winter rape and wasn't inferior to the variants in which there wasn't used Azobacterin and dozes of nitrogen fertilizers were much more higher. The highest yield increase (4,1 c/ha) the analyzed associative nitrogen fixer provided in the variant with nitrogen application in doze of 110 kg/ha in the beginning of renewal of spring crop vegetation. The maximum rapeseed yields (33,4 c/ha) the winter rape of Lider variety were formed after application of Azobacterin in combination with 3-time nitrogen application (N100 + N50 + N20) with the stated yield increase of 3,2 c/ha
