“…A means of increasing the level of biological fixation of air nitrogen is the inoculation of seeds by highly effective strains of tuber bacteria (Davis, Tim, 2017;Rai et al, 2017;Bollman &, Vessey, 2006, Merkushyna, AS, 2013Xing et al, 2016). In the research papers, there is enough information available on the use of natural growth stimulators and bacterial agents aimed to activate the production process through morphometric changes in the legumes (Xing et al, 2016;Pantsyreva, 2016), cereals (Muhammad and Muhammad, 2013;Luo et al, 2017;Zhao et al, 2017), oilseeds (Khodanitska and Kuryata, 2011;Fu et al, 2014;Froschle et al, 2017), vegetables (Palamarchuk II, 2017, Tubiis et al, 2016Alexopoulos et al, 2017), industrial crops (Khhodanitska and Kuryata, 2011;Mohammad and Mohammad, 2013;Rai et al, 2017), fruit crops (Ahmed et al, 2012;Cru-Castilloa et al, 2014), medicinal and decorative crops (Gouveia et al, 2012;Aremu et al, 2017;Madzikane-Mlungwana et al, 2017). Bacterial agents and growth stimulators also increase crop resistance to adverse environmental and biotic factors due to the changes in hormonal status and the activation of antioxidant plant sustems (Javid et al, 2011;Muhammad and Muhammad, 2013;Piotrowska Niczyporuk et al, 2014;Tubi's et al, 2016;Xing et al, 2016;Pantsyreva, 2017).…”
