The influence of benefit microorganisms on yield and quality of soybean grains under conditions of reduced nitrogen fertilization

Abstract

The aim of this study was to investigate the possibility to reduce the application of mineral nitrogen fertilizers through the application of beneficial microorganisms (genus Bradyrhizobium, Azotobacter, bacteria Pseudomonas fluorescens, Bacillus spp., etc.). Research was conducted during 2013 and 2014 on Eutric brown soil. The experiment was set up in a split-block scheme with 12 different variants in 4 repetitions: two soybean cultivars were used; two different treatments of nitrogen fertilizers and three different treatments of microbiological preparation were applied. Analysed parameters were soybean grain yield (kg/ha) based on 13% moisture, protein content (%), oil content (%) and hectolitre mass (kg). Given that the climatic conditions in the second year of research were more favourable than in the first year of research, all the elements of research, including control variants, achieved better results in the second year of research. All variants treated with microbiological preparations, either by application in soil or by application in soil combined with foliar treatments, also achieved statistically significant differences compared to the control variants.

Soil Organic Carbon and Its Controlling Factors in the Lakeside of West Mauri Lake along the Wetland Vegetation Types

“…Therefore, it is not a scientific choice to unilaterally increase soil carbon sequestration potential through fertilization. According to the report by Kristek et al [44], microbiological preparation is better than chemical fertilizers and can reduce nitrogen fertilizers by 30%, suggesting that biofertilizers may be a good option. In addition, effective nutrient management aimed at curbing phosphorus input has cleaned up many lakes in the western world and successfully controlled cyanobacterial blooms [45,46].…”

Antioxidative Response and Phenolic Content of Young Industrial Hemp Leaves at Different Light and Mycorrhiza

“…Fungi establish symbiotic communities, the so-called mycorrhiza, with more than 90% plant species. In this way, they help the plant absorb water and minerals more quickly and efficiently, and in return, the fungus takes carbohydrates that plants produce with photosynthesis [ 24 , 25 , 26 ]. The symbiotic relationship between mycorrhiza and plants is one of the most abundant symbiotic activities in the plant kingdom, which exists in most ecosystems, and its role in soil and plants has been an interesting scientific subject for more than 200 years [ 27 ].…”

“…are saprophytic fungi that are considered the most important group of microorganisms that can be found in most arable soils, mainly in plant roots, soil, and plant waste. Trichoderma spp., can promote plant growth and increase leaf and dry matter mass, but it also has great potential as a fungicide in biological control [ 25 , 28 , 29 , 30 , 31 , 32 , 33 ]. Zielonka et al [ 34 ] mentioned that plants, including Cannabis sativa, created a unique strategy to counteract biotic and abiotic stress through symbiosis with the environment of microorganisms and soil is the centre of microbial diversity in which plants selectively establish relationships with the microbiome to satisfy their needs.…”
