The aim of this study was to highlight the action effects of a fertilizer containing microelements – REACOM (Ukraine) and a biostimulator – ATONIK (Romania). It was followed: the effect of different concentrations of REACOM on seeds germination and growth of Lycopersicum aesculentum L. seedlings, in the ase of Ace 55 VF, Sf. Pierre and Russian black varieties; the influence of REACOM treatment time on tomatoes seeds on some physiological processes (germination, growth); the influence of various concentrations of ATONIK and of treatment time on germination and growth of Lycopersicum aesculentum L., in the case of Ace 55VF, Sf. Pierre and Russian black varieties (germination, growth); comparing the action of the two growth stimulating products on the physiological yield of Lycopersicum aesculentum L. The obtained results recommend for the tomato culture the ATONIK product as a growth stimulator in the mentioned concentration on the label; the use of higher or lower concentrations leads to unsatisfactory results. In the case of REACOM, the strict failure of prospectus has led to the slowing or even to the destruction of tomato seeds. The growth of tomato seedling is stimulated by the presence of ATONIK AIII - 6 days for the Sf. Pierre variety, and in the case of Russian black variety, AII-6, 9 or 12 days.
