Low temperatures, even the frost appearance at the beginning and at the end of maize vegetation are often phenomenon in the mountainous region of the Republic of Srpska. Field experiment with maize hybrid NS 3014 (FAO 300) was set up in the area of Mokro settlement in Pale Municipality (43°52’34.03” (N) 18°36’28.56”(E) i 905mnv) with two treatments (untreated and foliar treatment with “Sinergon 2000”) combined with adding different quantities of nitrogen (N) fertilizer (0,40,80 and 120kg/ha). The paper aims at analyzing their impact on yield and quality of maize forage. Foliar treatment with “Sinergon 2000” did not significantly increase the yield of maize silage, dry matter and proteins. One of the reasons for getting such result could be the absence of low temperatures (including the appearance of frost too) which is prerequisite for maize growth and its development during vegetation period. Increase of proteins content in dry matter using “Sinergon 2000” in all treatments can indicate its positive impact on the protein synthesis which should be further tested in the future researches. Taking into consideration that maize has high demand for N, positive influence of N fertilizers on maize silage yield, dry matter and proteins - which is only visible when the content is very high- could be result of a difficult absorption of mineral fertilizers in the drought period in the maize fields due to small quantities of rainfalls in June and July.
