Soil is the basic source of the elements for plants, and also for animals that eat plants and people who consume plant and animal products. However, if the soil is deficient in a particular element and cannot provide sufficient quantities for plant nutrition, disturbances in the growth and development of the plants, as well as animals occur. Biofortification of forage crops, i.e. fertilization with microelements, is one of the ways how a higher content of essential elements for livestock, primarily Se and Zn, can be achieved in plants. A field experiment with alfalfa was set up in 2014 in Ljutovo, Subotica, with the aim to investigate the effect of foliar fertilization with Se and Se and Zn in combination on the yield, content of Se and other observed elements in alfalfa. The following treatments were investigated: control without fertilization; 5 g Se ha-1 , 10 g Se ha-1 , and 10 g Se ha-1 and 0.5 kg Zn ha-1 . Two-year results showed that the Se fertilization did not affect the yield and content of P, K, Fe, and Mn. Selenium application increased the content of this element in the dry matter (DM) of alfalfa, however, compared with the control treatment, significantly higher only on the treatment with a higher dose of Se. The content of Se in the DM of alfalfa is highly positively correlated (R = 0.85) with the applied dose, ie with the application of 1 g Se ha-1 the Se content in the plant mass is increased by 0.041 mg Se kg-1 DM. Given the antagonism between selenate and sulfate the uptake in plants, the use of Se and Zn in combination did not negatively affect the Se content and, as expected, positively influenced the increase in Zn content as well as Cu. The foliar application of Se or Se and Zn in combination can be recommended as one of the measures in the production of forage plants in the agro-ecological conditions of Vojvodina, with aims to improve the mineral composition of feed.
