ABSTRACT / САЖЕТАК:
The aim of the research was to determine the impact of the EM Aktiv preparation in the maize crop (ZP 427 and ZP 548) at 160, 120, 102 kg ha-1 N in 2017 at the location of the municipality of Vladimirovci. During the growing season, there was a pronounced water deficit. The preparation was applied in three variants: EM1 – control, EM2 – foliar 2 x 6 l ha-1 in the phenological stages of 5-7 leaves and after 15 days; EM3 – the preparation was introduced into the soil 7 days before sowing 30 l ha-1 + EM2. The mass of 1000 grains, the height of the yield and the nitrogen content in the grain were determined. Application of 160 kg ha-1 nitrogen had the greatest effect on the weight of 1000 grains, and 120 kg ha-1 The production of maize on a global level takes place in a way that affects the degradation of resources and elements of the environment, the increasing dependence on mineral fertilizers and pesticides, which leads to the production of greenhouse gases and a negative impact on climate change. Today, N on grain yield in all treatments. The treatments had a positive effect on both traits. Higher values of the tested properties were found in the EM3 treatment. The applied factors did not have a statistically significant effect onthe nitrogen content of maize grains.

the municipality of Leskovac, on alluvium land type. In the experiment, 6 maize
hybrids of different vegetation lengths 400-600 were sown (ZP 434, NS 4023, ZP
555, NS 5051, ZP 666, NS 6030). The hybrid NS 6030 (10.248 t ha-1) had the
highest average yield in 2014, while the hybrid FAO group 400 NS 4023 (9.467 t
ha-1) had the lowest. The highest average yield in the year 2015, unfavorable for
corn production, was achieved by the hybrid FAO group 400 ZP 434 (6.938 t ha–

2015, being that the average temperatures were warmer than in 2014, and it had
fewer amounts and worse distribution of precipitation, late sowing had a very
bad effect on all hybrids, especially on FAO 600 hybrids.
