Abstract
Treatment of corn seeds with growth stimulants is a newer measure in the process of seed processing and production. The aim of the study was to determine the effect of different growth stimulators on the initial growth of young maize plants. The research was conducted on three maize hybrids whose seeds were treated with four commercial variants of growth stimulator treatment. After germination, measurements of plant height and mass of the aboveground part of the plant in the vegetation phase of the initial growth of maize were performed. The results of the research showed a statistically very significant influence of growth stimulators on the height of the plant and also on the mass of the aboveground part of the plant. The greatest positive effect was measured in maize hybrids OSSK 403 for both observed agronomic traits. The application of growth stimulators on maize hybrid seeds is very simple in the finishing process and due to the subsequent positive effect on the initial growth of maize hybrids can be recommended in maize production. The positive effects of growth stimulants on plant metabolism greatly help the maize plant to overcome negative agroecological impacts.
