“…These results suggest that SM may result in higher yield and nutritional quality of tomato fruits. According to Joe et al (2012) and Souza et al (2017) the inoculation of endophytic bacteria by the seed microbilization method is the most efficient, besides being economical, safe, reliable and fast (Hallmann et al, 1997).…”

Endophytic bacteria can promote growth and improve the quality of plant production. The objective of this work was to evaluate the efficiency of inoculation of a mix of non-host endophytic bacteria isolates in the nutrition of tomato fruits cultivated, fertilized with rock powder and different doses of nitrogen. The experimental design was in randomized blocks, in a factorial arrangement (2 × 6 + 3), with four replications. The treatments consisted of two methods of inoculation of the mix of endophytic bacteria: seed microbiolization and post-emergence inoculation; six doses of nitrogen fertilization: 0, 129, 258, 387, 516 and 645 kg ha-1; and 3 controls (without inoculation of the bacterial mix). The average export of macro and micronutrients in tomato fruits was, in descending order: K > N > P > Ca > Mg > S (averages of 1.33; 0.46; 0.07; 0.06; 0.05 and 0.05 g plant-1, respectively) and Mn > Cu > Fe > Zn (means of 2.67; 1.98; 1.71 and 0.79 mg plant-1, respectively). The inoculation method by seed microbiolization associated with nitrogen doses promoted significant increment in the dry mass of the fruits and in the content of the nutrients P, Ca, Zn, Fe and Mn.

“…In recent years, studies have shown that soil microorganisms, through the production of organic acids, can accelerate the release of nutrients from these rocks, increasing availability in the soil solution for plant absorption (Moreira;Siqueira, 2006). Several studies have emphasized the selection of phosphate solubilizing microorganisms (Massenssini et al, 2016;Schueler;Dourado;Rizzo, 2019;Terra et al, 2019), and presented promising data on the potential for application in the field (Dabaja et al, 2019;Souza et al, 2017;Terra et al, 2019). Thus, these microorganisms are biotechnological alternatives that can enable the use of natural phosphate from national deposits, such as Araxá and Catalão natural phosphate.…”

Brazil imports most of the phosphate fertilizers used in agriculture, however, it has national deposits in its territory that can supply part of the domestic market demand. In order of these to be used effectively, it is necessary to identify techniques to accelerate the release of phosphorus (P) from these rocks. The objective was to evaluate the influence of inoculation with phosphate solubilizing bacterial isolates (PSB) and decomposition of different plant residues in the solubilization of Araxá natural phosphate (ANP). Two experiments were carried out in a completely randomized design in a 5 x 4 factorial scheme, with four replicates. The first experiment evaluated the solubilization of ANP by PSB in culture medium with four different sources of carbon: glucose, saccharose, cellulose, and pectin. The treatments were incubated for seven days and then were analyzed the P concentration and pH values. In the second experiment, the ANP was applied in 300 cm3 of soil, placed in incubation chambers, with six grams of dry and crushed plant material of white oat, brachiaria, crotalaria, lupine, and the inoculation of PSB. Decomposition was evaluated weekly by quantifying the carbon of the CO2-C released and, after 42 days was analyzed the concentration of P in the soil. It was observed that the carbon source directly influences the solubilization of ANP by PSB, especially the genus Burkholderia. Treatments containing crotalaria and lupine residues showed higher CO2-C values, and the ones containing plant residues associated with BSF inoculation obtained the highest levels of P in the soil.

In search for a more sustainable agriculture, the use of microorganisms as a technology is increasingly being used by agriculture throughout the world. This is due to the fact that it minimizes the use of agricultural supplies reducing environmental costs and impacts, based on the beneficial and natural relationships between edaphic organisms and cultivated plants. The rhizobacteria habitat in the soil establishes biochemical relationships with the plants acting as plant growth promoters (PGPR). Many of these bacteria are producers of phytohormones and enzymatic compounds with the capacity to provide important nutrients for plants. In this context, the present work aimed to quantify the potential of indole-3-acetic acid (IAA) production and the phosphate solubilization of rhizobacteria from Western Paraná. Isolates grown in DYGS medium plus tryptophan were quantified by colorimetry for the production of IAA. Iron phosphate solubilization was carried out by inoculation in modified Pikovskaya medium (PKV) and quantified by colorimetry. The results were evaluated by the Scott-Knott test at 5% using the SASM-Agri program. The highest IAA production was observed with the addition of tryptophan to Erwinia (219); Enterobacter (302) and Salmonella (57). Isolates Falsibacillus (438) and 505 showed higher efficiency in the iron phosphate solubilization. Isolates Enterobacter (130), 438 and Enterobacter (151) were highlighted in both tests, being characterized as a great potential for use in biotechnological products.
