Istraživanja su sprovedena u periodu 2013-2015 na oglednom dobru Instituta za ratarstvo i povrtarstvo u Novom sadu, na zemljištu tipa karbonatni černozem u okviru održive proizvodnje soje...
Institute of Field and Vegetable Crops in Novi Sad, on soil type chernozem carbonate within the sustainable production of soybeans. In the research was included soybean cultivar Valjevka, 0 maturity group, the length of the vegetation period to 120 days. The field experiment was conducted in a split plot design with four replications with randomized design (total 18 variants). The research included three factors: Factor A are years, because on the yield of soybean grain affecting agrometeorological conditions in the phenological stages of vegetative and generative growth. Factor B are different types and amounts of fertilizers. For plant nutrition was used poultry manure (N 4,5%, P2O5 2,7%, K2O 2,2%, MgO) in three different amounts of Ø (control), 750 kg/ha and 1300 kg/ha in combination with microbiological preparation “EM Aktiv” (incorporation of soil and foliar treatments) which are products of life activities large groups of effective microorganisms: Lactobacillus plantarum, Lactoba...cillus casei, Streptococcus lactis, Rhodopseudomonas palustris, Rodobacter sphaeroides, Saccharomyces carevisiae, Candida utilis, Streptomyces albus, Streptomyces griseus, Aspergillus oryzae, Mucor hiemalis. Faktor " is the stimulation of seeds with low-frequency electromagnetic fields, or with dashed sinusoidal wave (sinusoid) so called pulsed electromagnetic field (PEMF), which is performed with the device of specific spectral content of low frequencies from 15 Hz exposure 30 minutes, performed immediately before sowing. The aim of this study was to examine the basic morphological characteristics, the amount of grain yield, the qualitative traits (contents of protein, oil and phytate phosphorus) soybean cultivars grown in the system of sustainable agricultural production. In addition, the aim of the study was to investigate the influence of the applied factors on the production characteristics of the soil: agrochemical properties (content of easily accessible form of nitrogen) and the basic parameters of the biological value of soil as seen through the total abundance of microorganisms, number of physiological and systematic group (Azotobacter, aminoheterotrophs, oligonitrophilic bacteria, fungi and Actinomycetes)...
