Economic and energy efficiency of maize cultivation depending on mineral fertilizers and foliar fertilization

The purpose of the research was to determine the economic and energy efficiency of maize cultivation technology for the application of mineral fertilizers N158P52K52 and fertilizing fertilizers with Nutrimix (1.0 kg / ha), Nutribor (0.5 kg / ha) and Micro Mineralis Maize (1.0 l / Ha). Application of mineral fertilizers to corn and non-root fertilization of crops with fertilizers with a trace element contributed net profit at the level of 41773 - 47064 UAH / ha, profitability of 142-151% and energy efficiency factor (Kee - 4,73-4,87) in the Ajax hybrid and respectively, 237 MB in the hybrid Orzhitsa, the indicated indices were: 39298-44787, 144-155% and 4,56 -4.72 respectively. Such a range of indicators is due to the use of fertilizers in nutrition, distinctly and consistently for one and two single applications in the phenological phases of the 4th, 8th and 4th and 8th leaves. The application of fertilizers with trace elements in foliar nutrition provided a slight increase in the energy and economic efficiency of corn cultivation.
