The strategy “from farm to fork” assumes a reduction in the usage of fertilizers and plant protection products in EU agriculture. The aim of this study, conducted over the years 2017–2019 in several locations in Poland, is to evaluate the application of growth activators with and without plant growth-promoting rhizobacteria to reduce mineral nitrogen fertilization without negative effects on the root yield. We studied the effect of these activators on selected soil properties. The experimental treatments included the application of the growth activators Penergetic (K + P) and Azoter, which contains the bacteria Azotobacter chroococcum, Azospirillum brasilense, and Bacillus megaterium, before sowing or during vegetation. The nitrogen rates were reduced by 30% in comparison to full nitrogen mineral fertilization (control treatment). In selected experiments, the application of Penergetic and Penergetic with Azoter caused a higher content of nitrate nitrogen (N-NO3) and ammonium nitrogen (N-NH4) after the sugar beet harvest as well as higher contents of mineral nitrogen (Nmin), P, K, and Mg in the soil in comparison to the treatment with the full dose of mineral nitrogen fertilization. The obtained results proved that it was possible to reduce the mineral application of nitrogen by 30% without a decrease in the biological and pure sugar yield, and even with an increase in the sugar yield caused by the application of the growth activators Penergetic (K + P) and Azoter.

“…Therefore, plant probiotics and plant growth-promoting microorganisms (bacteria, fungi, etc.) are somewhat synonymous with each other and are part of a complex microbial community that either colonizes the rhizosphere (rhizomicrobiome; Ravichandran et al, 2022) diffuse in or localizes in plant tissues (endophytes; Pandey et al, 2022;Rai et al, 2023) and contribution to beneficial functional traits in favor of plants (Gosal et al, 2017). These beneficial traits include enhancement in plant growth and productivity (Gavelienė et al, 2021), amelioration of abiotic and biotic stresses in plants (Santoyo et al, 2021), lowering the challenges of climate changes effects (Fiodor et al, 2021), and biofortification benefits via improving micronutrients levels in crop edibles (Upadhayay et al, 2018(Upadhayay et al, , 2021(Upadhayay et al, , 2022a.…”

Synergistic impact of nanomaterials and plant probiotics in agriculture: A tale of two-way strategy for long-term sustainability

Modern agriculture is primarily focused on the massive production of cereals and other food-based crops in a sustainable manner in order to fulfill the food demands of an ever-increasing global population. However, intensive agricultural practices, rampant use of agrochemicals, and other environmental factors result in soil fertility degradation, environmental pollution, disruption of soil biodiversity, pest resistance, and a decline in crop yields. Thus, experts are shifting their focus to other eco-friendly and safer methods of fertilization in order to ensure agricultural sustainability. Indeed, the importance of plant growth-promoting microorganisms, also determined as “plant probiotics (PPs),” has gained widespread recognition, and their usage as biofertilizers is being actively promoted as a means of mitigating the harmful effects of agrochemicals. As bio-elicitors, PPs promote plant growth and colonize soil or plant tissues when administered in soil, seeds, or plant surface and are used as an alternative means to avoid heavy use of agrochemicals. In the past few years, the use of nanotechnology has also brought a revolution in agriculture due to the application of various nanomaterials (NMs) or nano-based fertilizers to increase crop productivity. Given the beneficial properties of PPs and NMs, these two can be used in tandem to maximize benefits. However, the use of combinations of NMs and PPs, or their synergistic use, is in its infancy but has exhibited better crop-modulating effects in terms of improvement in crop productivity, mitigation of environmental stress (drought, salinity, etc.), restoration of soil fertility, and strengthening of the bioeconomy. In addition, a proper assessment of nanomaterials is necessary before their application, and a safer dose of NMs should be applicable without showing any toxic impact on the environment and soil microbial communities. The combo of NMs and PPs can also be encapsulated within a suitable carrier, and this method aids in the controlled and targeted delivery of entrapped components and also increases the shelf life of PPs. However, this review highlights the functional annotation of the combined impact of NMs and PPs on sustainable agricultural production in an eco-friendly manner.

“…Represented by a wide variety of rhizosphere bacteria, the use of those microorganisms is a viable alternative and meets the new expectations of the consumer market, by adding quality to the products and decreasing the use of pesticides (Gosal et al, 2017). Plant growth improvement can be triggered by PGPR through different mechanisms or by a combination of different factors, such as auxin indole-3-acetic acid (IAA) production, hydrogen cyanide production (HCN), phosphate solubilization and biological nitrogen fixation (Kielak et al, 2016;D'Agostino et al 2017).…”

Chrysanthemum production stands out in ornamental plants market and several techniques can improve the production of this plant. Among them, is the use of beneficial microorganisms such as plant growth promoting rhizobacteria (PGPR); however, the use of PGPR has not been explored enough so far in chrysanthemum production, especially in field conditions. With regards to rhizobacteria, the group, Pseudomonas, can be explored as a good alternative to improve plant development. Hence, the objective of the present study was to evaluate the effect of PGPR on seedlings and, on the field experiments, plants development and the impact on rhizosphere soil. The strains of Pseudomonas putida IAC-RBcr5 and IAC-RBcr2 were able to improve chrysanthemum shoot biomass up to 40%. In addition, the plants treated with these strains had increased number of flowers, which is a desirable feature for the flower market. This is the first study to demonstrate the effect of P. putida strains on chrysanthemum seedlings and cut flowers grown in tropical field conditions.
