The article reflects the results of the research conducted with studies on the performance of maize hybrids and shows the economic efficiency of cultivation of different maize hybrids depending on mineral fertilizer. Mineral fertilisers are the most important element in the technology of growing new maize hybrids Therefore it is very important to study the effect of fertilizers. Therefore, it is very important to study the effect of fertilizers on grain productivity corn hybrids, which are most common in our region and important economic importance. The aim of the research was to analyze influence and interrelation of productivity and economic efficiency cultivation of maize hybrids. Ukrainian agrarians traditionally grow maize for grain, and it occupies a significant place in the structure of grain production. In recent years In recent years, all agricultural producers note a sharp increase in gross yield The crop has been appreciated as one of the most important high-yielding and versatile cereal crops Cereals with a versatile purpose, which are grown for food, fodder and technical purposes, Forage and technical uses In Ukraine maize is used for both food and feed purposes. both for food and technical purposes, as well as for the feed industry. fodder production. An important area of sustainable development of the global Farming is one of the most important areas of sustainable global economic development at the beginning of the 21st century. An important element of sustainable development in global economic development in the beginning of the 21st century, including in the agricultural sector, is the improvement and implementation of new resource-, energy-saving and environmentally friendly technologies. It is proved that use of mineral fertilizers has a positive impact on for formation of grain productivity indicators of maize hybrids. What can be noted with the following statement, the more nitrogen fertilizers were applied the more was the yield. When comparing to the variant without fertilizer corn hybrids yield increased by 83-90% and amounted to 12,18-12,88 t/ha. From this we can conclude that the most promising fertilization system for maize hybrids is the application of cultivation of N128P128K128 with a subsequent addition of nitrogen in a dose of N70 in the phase of 6- 7 leaves of maize providing a gross yield of 12.18-12.88 t/ha of grain with an level of profitability of production 219-232%. In addition it is indicated in the publication of the main aspects of the technology of growing maize on grain, which underlie the improvement of production efficiency indicators first of all, yield, profit and level of profitability.
