“…These findings support the hypothesis of multiple researches triggered by A. brasilense in cereal which go far beyond the capacity of biological nitrogen fixation (Pankievicz et al, 2015) and synthesis of phytohormones (Bashan and De-Bashan, 2010). The inoculation with A. brasilense signals intrinsic absorption processes (Fukami et al, 2017) and solubilization (Rodriguez et al, 2004;Arzanesh et al, 2011;Banik et al, 2016), promoting better use of micronutrients (Galindo et al, 2019b), which, therefore, highlights the need for more specific studies to understand these mechanisms and metabolic pathways of plants.…”

“…Being a constituent of amino acids, proteins, chlorophyll, and several secondary metabolites, N is the most interfering nutrient in the productivity of crops, especially non-atmospheric N 2 fixers (Marschner, 2012). It is among the mineral nutrients that has been noted to have higher concentrations in plant tissues and grains and makes it the most required nutrient in wheat crop productivity (Galindo et al, 2019b). The average accumulation of nutrients in the shoot at the wheat flowering stage of both cultivars resulted in a decreasing trend of K > N > P > Ca > S > Mg. Phosphorous (P) has several important functions in plants, is a constituent element of the ATP molecule, and has a role in the supply and storage of energy in metabolic processes, such as the synthesis of organic compounds and the absorption of nutrients, in addition to being involved in the phosphorylation and electron transport reactions of photosynthesis (Hawkesford et al, 2012).…”

Agricultural practices that allow a productive increase in a sustainable manner are becoming increasingly necessary to feed an ever-growing global population. The inoculation with Azospirillum brasilense has the potential to reduce the use of synthetic mineral fertilizers with efficient capacity to promote plant growth and increase nutrition. Therefore, this research was developed to investigate the potential use of A. brasilense to increase the accumulation of macro- and micronutrients and its influence on grain yield, plant height, and spike population in two wheat cultivars (CD1104 and CD150), under irrigated conditions in the Brazilian Cerrado. The study was carried out in a Rhodic Hapludox under a no-tillage system. The experiment was designed in randomized blocks with six replications, arranged in a 2 × 2 factorial scheme: two cultivars (CD150 and CD1104) and two levels of inoculation (control and with A. brasilense). The inoculation with A. brasilense provided greater accumulation of micronutrients in the aerial part of the wheat. In the cultivar CD1104, B and Cu had an accumulation 27.7 and 57.4% higher compared with those of the control without bacteria. In the cultivar CD150, Azospirillum increased the accumulation of B, Fe, and Mn by 43.8, 49.9, and 22%, respectively, and reduced Cu by 21.9%, compared with those of the control. The cultivar CD150 has greater efficiency to accumulate N (+35.5 kg N ha−1) as compared with the cultivar CD1104. Interactions between inoculation and cultivars resulted in greater accumulation of S and K in the shoot of the wheat cultivar CD150, as well greater accumulation of Cu in CD1104. In growth assessments, inoculation or cultivars did not statistically influence wheat grain yield and spike population. Howevere, for plant height, the CD1104 genotype has 13.1% bigger plant height on average than that of the CD150 genotype. Inoculation can contribute more sustainably to wheat nutrition.

“…the study proved an average yield increase of 36.8% and 13.5% when the inoculation was associated with N application rates of 70 and 140 kg ha −1 , respectively. The inoculation of seed with Azospirillum brasilense together with the application of 140 kg N ha −1 caused an increase in wheat grain yield [21,26]. Inoculation with A. brasilense in treatment with the application of 100 and 150 kg N ha −1 caused an increase in grain yield by 19.6% and 18.8%, respectively [27].…”

The introduction of the “Farm to Fork” strategy in the EU will require a significant reduction in mineral nitrogen fertilization, and therefore the introduction of innovative production technologies to prevent a decline in agricultural production. Studies carried out in several locations in Poland in 2016/17–2018/2019 tested the possibility of replacing 30% of the dose of mineral nitrogen with growth activators alone, in combination with plant growth promoting rhizobacteria in the cultivation of winter wheat. It was confirmed that these two combinations allowed the obtention of a higher yield of grain by 13%, compared to the full nitrogen dose. Simultaneously, the grain quality did not change significantly. In some locations, a decrease in the content of nitrates in the soil was observed, which may mean a greater uptake of this nutrient by plants and an increase in the content of some available macro- and micro-elements, mainly phosphorus, magnesium, zinc, copper and iron, and soil organic carbon. Introducing the studied treatment and limiting the fertilization with mineral nitrogen of wheat in Poland by only 30 kg ha−1 N would save its consumption by 72 thousand t per year.
