On the farm Strazdi, Tervete region, Dobele district (Latvia) demonstration for determination of different outside root fertilizers impact on spring rape yield and quality have been carried out. Conclusions: (1) the largest crop yield - 3.8 t haE-1 have been obtained in variant with use of Mikrotop, in control variant crop yield was 2.7 t haE-1, the smallest yield from treatment variants have been obtained using Suplo - 3 t haE-1 and Vito - 3 t haE-1; (2) largest 1000-grain weight increase - 131% in correlation against control have been ascertained in variant with Mikrotop. The smallest 1000-grain weight increase in correlation against control have been obtained in variant with Suplo - 116%; (3) the largest oil content have been ascertained in variant, where have been used Mikrotop - 38%. In the control variant oil content was 35%; (4) once spraying of microelements in spring oilseed rape not provide insufficient level with microelements; (5) the largest economical efficiency was using of Mikrotop - 528.5 Ls haE-1; using others fertilizers, have been obtained such brutto coverage: with Hydro Plus - 460.5 Ls haE-1, Suplo - 402.0 Ls haE-1, Vito - 389.5 Ls haE-1.
