Kovalenko Oleg Anatolyevich – Candidate of Agricultural Sciences, Associate Professor of the department of plant growing and landscape gardening in Nikolaev National Agrarian University (54020, Nikolaev, st. Georgi Gongadze, 9. e-mail: kovalenko_oleh@ukr.net).

In the article the results of the study of the influence of extracorporeal feeding on microfertilizers "Ekolist monozink", "Corn germ," а bacterial preparation "Biomag" and а regulator of plant growth on the area of the leaf surface of the pumped leaf in maize hybrids are highlighted. Different variants of application of preparations in a phase 5-7 and 10-12 leaves of a corn and their influence on а square at a swollen leaf are investigated. The effectiveness of the products of foliar fertilization on the formation of an assimilation apparatus of corn is analyzed.
