In course of the research there was studied the influence of fertilizers on productivity of tomato (Lycopersicon esculentum). The research was realized in the conditions of the Republic of Belarus on sod-podzolic sandy soil during 2008-2009. It was revealed that application of full mineral fertilizer N80P120K100 has provided an increase of a crop yield of tomatoes fruits of 10.1 t/ha at total crop yield 35.7 t/ha, mass of 1 fruit 79 g and ovary fruits of 77.2%. Processing of tomato plants by a bacterial preparation Fitostimofos has provided identical agronomical efficiency in comparison with a full mineral fertilizer. Nitrogen content in tomato fruits was 1.09 -1.17%, phosphorous – 0.28 - 35%, potassium – 2.07 - 2.09%; in shaw – 2.63 - 2.75, 0.82 - 0.95 and 5.02 - 21% respectively. Specific nitrogen yield in 1 t of fruits and relevant quantity of tomato shaw made 2.0 – 2.1 kg/ha, phosphorous – 0.6 – 0.7, potassium – 3.8 – 4.0 kg/ha.
