Climate changes towards global warming and drought are leading to disruption of the world's water balance. Maize is a crop of strategic importance for agriculture. Therefore, it is important to study the potential capabilities of the crop at different levels of agrotechnics. For this purpose, a field experience with five hybrids of corn was set. Observations were made on the productivity of hybrids for silage and for grain. The development of the hybrids during the growing season was monitored. We tested three levels of foliar fertilization. The obtained yields and parameters of the structural elements of the yield of the five hybrids show how responsive each is to optimizing the nutritional regime. The field experience was carried out under irrigated conditions. Trends are registered after conducting a statistical analysis of the results.
