The influence of effective microorganisms on some characteristics of different maize

Abstract

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 on the nitrogen content of maize grains.
