In the experiment, we examined the effect of water deficit and amino acid foliar treatments on the development of maize in the year 2023. The experiment was carried out under controlled conditions in an experimental climate cabinet. The growing pots had a volume of 0.5 liters, in which 4 water supply levels were examined. We looked at the growth and development of maize at 20, 40, 60 and 80% of the soil water capacity. We examined root length, shoot growth, biomass and leaf surface development. With the improvement of the water supply, the development of the maize improved as expected! The favorable effect of the amino acid treatments was confirmed in the lower water supply level! Amino acid foliar fertilization increased the root mass by 7-19%! The root length also changed positively. Relative chlorophyll content (SPAD) was measured in the shoot. The relative chlorophyll content also developed favorably, slightly increasing as a result of the amino acid foliar treatment. The positive effect was also visible in the case of an increase in the leaf area, the leaf area index (LAI) increased by 6.8 - 20.1 % as a result of the amino acid treatments. During the treatments, we found that amino acid treatments can reduce the stress effects caused by drought! The treated plants were stronger and more developed! These treatments may play an important role in the treatment of drought stress in the future! We would like to continue the experiments in the future in order to develop an efficient technology for the conditions of dry farming.
