Summary: The article presents the studies results of the foliar fertilization influence with microfertilizers and growth stimulants on the formation of the leaf surface area of corn hybrids, as the maincomponent of photosynthetic potential of plants and their productivity in general. One of the modern directions of increasing the yield and quality of crop products is the introduction of energy-saving technologies in agricultural production with the use of plant growth regulators and microfertilizers.Their use for pre-sowing seed treatment provides intensive plant growth and development, high field germination, and spraying plants during the growing season promotes plant growth and development, increasing their resistance to adverse weather conditions, diseases, increasing yields. As a result, growth regulators and microfertilizers are increasingly becoming an integral part of intensive crop technologies. In addition, ensuring the productivity of plants and the optimal leaf surface area can be achieved not only by using a single growth stimulant or microfertilizer, but also their complex. Therefore, it is important to study the use of a complex of plant growth stimulants and microfertilizers, which, in turn, will ensure the realization of the biological potential of corn plants, and reduce costs per unit of output.According to the program of our research, we studied the influence of microfertilizers and growth stimulants on the growth, development and formation of the assimilation surface of corn hybrids of different maturity groups. According to the research results, the highest leaf surface area was recorded in the medium-ripe hybrid Monica 350 MW, 42,74 thousand m2 / ha using foliar fertilization in the phase of 5−9 leaves with a complex of microfertilizers Nanomix-corn and growth stimulant Emistim S. Area leaf surface in the middle-early hybrid yield of 37,96 thousand m2 / ha, was also recorded for the use of this complex. Also, the use of only microfertilizers Nanomix-corn, led to an increase in leaf area for all studied hybrids.
