The article reveals the research results of influence of fertilizers and meliorants on the phytoproductivity plants of white cabbage in various phenophase at simulated levels of soil contamination by lead. It was investigated that, the applying of the organic and organo-mineral fertilizer system together with liming of the soil provides the slightest phytotoxic influence of lead ions on the whit cabbage plants in different phenophase, as well as its lowest concentration in various organs cabbage in a phase of technical maturity. The results of researches have revealed that the highest phytoproduction parameters of white cabbage plants (height of plants, diameter of the socket, leafs area, head diameter, height of external cabbage stalk, head mass, yield) noted by application of the organic and organicmineral fertilizer system at norms Biohumus 8 t/ha + CaCO3 and N68P68K68 + Biohumus 4 t/ha + CaCO3 5 t/ha.
