ECONOMIC EFFICIENCY IN CULTIVATION OF MAIZE HYBRIDS OF DIFFERENT GROUPS OF MATURITY IN CONDITIONS SRF «AHRONOMICHNE»

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