Popis: The most important role in crop formation and its chemical composition is fulfilled by the balanced nutrition of plants with macro and microelements. The agrochemical approach to plant nutrition regulation is based on the removal of nutrients from the soil, the content and availability of macro- and microelements and their compensation by applying fertilizers to the planned yield. An insufficient content of several necessary microelements, namely Zn, Mo, Mn, and B, characterizes the Penza region soils In this regard, the issue of using complex forms of microfertilizers remains relevant. The influence of various concentrations from 0.1 to 10 % of the micro fertilizers preparation based on chelated complexes of elements on the germination of spring wheat seeds Triticum aestivum L. (the Tulaykovskaya 108 variety) and sunflower Helianthus annuus L. (hybrid P62LE122) was studied. The positive effect of low concentrations of the working preparation of microfertilizers on the germination of sunflower seeds was found out: an increase in germination energy from 17 %, seed germination from 5 %, and seedling biomass from 2%. With an increase in the preparation concentration, the suppression of seed germination was found. It was especially seen on spring wheat. It is assumed that the increased content of copper and zinc has a toxic effect on the cells of seedlings. The studied preparation of microfertilizers can be recommended for pre-planting treatment of sunflower seeds. Its concentration of elements includes: Mn - 30-150 mg/l, Zn - 20-80 mg/l, Cu - 3-10 mg/l, B - 10-50 mg/l.
