Sažetak
Selenium (Se) as an essential microelement in the soil is found in very small quantities, which causes malnutrition in plants, animals and humans. Therefore, agronomic biofortification, i.e. the process of applying microelements before or during crop vegetation with the aim of increasing the concentration of a certain microelement in the edible parts of the plant, is a measure to alleviate malnutrition. The aim of the research was to investigate the effectiveness of biofortification of soybean (Glycine max) and corn (Zea mays), which was carried out by foliar application of sodium selenate solution (Na2SeO4) in the amount of 0, 10, 20 and 30 kg/ha Se (Control, Se1, Se2 and Se3) in the locality of Tenja. The time of foliar application with battery sprayers was carried out in the phenophase of flowering. The concentration of selenium in the soybean grain in the control treatment was 0.05 mg/kg Se, and in the corn grain it was 0.11 mg/kg Se. Selenium concentrations in soybean grain in treatments Se1, Se2 and Se3 increased 14, 47 and 62 times compared to the control, while concentrations in grains of corn increased 3, 5 and 7 times compared to the control. No statistically significant difference in soybean grain was found between treatments Se2 and Se3, but both were significantly higher than Se1 and control treatment. In the case of corn, statistically significant differences were found in all treatments since Se3 treatment resulted in the highest Se concentration in corn (0.77 mg/kg), significantly lower were in Se2 (0.58 mg/kg) and Se1 (0.38 mg/kg) and the lowest in control without selenium application (0.11 mg/kg). Field experiments showed that agronomic biofortification was very efficient and could be used for significant increasing of selenium content.
