  The consumption of sweet maize is beneficial in the prevention of cardiovascular diseases, is effective in the prevention of lung diseases, stimulates brain function and its cellulose content helps the stomach and intestines. It is high in magnesium, phosphorus and iron and contains vitamins C, E and D in their natural form.
  The Hungarian-bred Honey normal sweet maize hybrid is excellent for fresh consumption at a tender stage of development. Laboratory tests have shown that Honey sweet maize can play an important role in a healthy diet. It has a favourable mineral content, with a potassium content of almost 10 000 mg/kg, a phosphorus content of 3217 mg/kg, a magnesium content of more than 1300 mg/kg and an important source of iron and zinc with values of 20.3 and 26.5 mg/kg.

  Since 1983, long-term field experiments have been carried out at the University of Debrecen's Látókép Experiment Site, where our research was also carried out. In the years 2021–2022, we examined the efficiency of biological foliar fertilisers under precision drip irrigation. Maize stands were treated at the 7–8-leaf stage with foliar sprays of Natur Plasma T biostimulant, Natur Active complex foliar fertiliser, and Zinc and Sulphur Mono additives. The applied foliar fertiliser treatments resulted in yield gains in both years. The use of these microbiological preparations allows rapid and efficient nutrient incorporation during the vegetative and generative cycles. During the growing season, important parameters of maize hybrids (SPAD, NDVI) were measured at critical phenophases (12-leaf stage, silking, physiological maturity). The obtained results showed that the incorporation of foliar fertilisers and biostimulants into agrotechnology improved the strength of maize stands and resulted in additional yield gains over and above the base fertilisation.
