“…Several other vegetables have been reported as responsive to microbial inoculants, including lettuce ( Lactuca sativa ) (Flores-Félix et al 2013; Mangmang et al 2014; Fasciglione et al 2015), carrot ( Daucus carota L.) (Flores-Félix et al 2013; Clemente et al 2016) and cucumber ( Cucumis sativus L.) (Mangmang et al 2015b). The increasing demands of the population on organic products may also stimulate the use of microbial inoculants for the production of vegetables.…”

More than one hundred years have passed since the development of the first microbial inoculant for plants. Nowadays, the use of microbial inoculants in agriculture is spread worldwide for different crops and carrying different microorganisms. In the last decades, impressive progress has been achieved in the production, commercialization and use of inoculants. Nowadays, farmers are more receptive to the use of inoculants mainly because high-quality products and multi-purpose elite strains are available at the market, improving yields at low cost in comparison to chemical fertilizers. In the context of a more sustainable agriculture, microbial inoculants also help to mitigate environmental impacts caused by agrochemicals. Challenges rely on the production of microbial inoculants for a broader range of crops, and the expansion of the inoculated area worldwide, in addition to the search for innovative microbial solutions in areas subjected to increasing episodes of environmental stresses. In this review, we explore the world market for inoculants, showing which bacteria are prominent as inoculants in different countries, and we discuss the main research strategies that might contribute to improve the use of microbial inoculants in agriculture.

“…These authors showed that, while the treatment with only N resulted in 28 g of roots, inoculation with the strain UCCBj-CE1 resulted in more than 60 g of roots. Clemente et al (2016) studied the response of carrots to Bacillus subtilis and B. methylotrophicus and observed increased fresh root mass in carrots. Without inoculation, the mean value was 5.9 kg m -2 .…”

“…Studies on inoculation benefits in carrots are scarce and focus on a small number of measured parameters. Evaluations by Kozusny-Andreani et al (2014), Matsuoka et al (2016) and Clemente et al (2016) reported the benefits of Pseudomonas and Bacillus as increased root length, fresh mass and dry root mass.…”

The objective of this study was to evaluate the effects of inoculation and co-inoculation with Bacillus subtilis and Pseudomonas fluorescens on carrots with reduced nitrogen use. A field experiment was carried on, with five treatments and five replicates, evaluating the growth and yield responses of inoculated carrots. Responses were observed in height only two weeks before harvesting, and the number of leaves was most affected from the beginning to the middle of the cultivation cycle. Although the fresh shoot mass was negatively affected by the inoculation treatments, the dry shoot mass did not respond to the rhizobacteria. The length of roots inoculated with P. fluorescens or co-inoculated with both bacteria increased from 21 cm, without inoculation, to 25 cm. The root volume and dry mass values were the same across the treatments. However, the fresh root mass was improved by between 70 and 81.8% with P. fluorescens and co-inoculation, respectively. More positive responses to inoculation were observed with reduced nitrogen levels, suggesting a potential in the rhizobacteria strains for use in reduced-input agricultural practices. Moreover, based on the findings, Pseudomonas fluorescens can be recommended as a plant growth-promoting microorganism in carrot cultivation.

“…Due to their peculiar characteristics, these microorganisms have been employed in agriculture, increasing the resistance of plants to various environmental stresses such as drought, heavy metals, and nutritional scarcity of the soil (CLEMENTE et al, 2016). However, in the agricultural sector, Bacillus species are more widely studied and used as growth promoters and biological control agents against pests and diseases (CLEMENTE et al, 2016).…”

The study refers to the activities developed in the soybean harvest period being carried out in an agricultural Farm, most of it is in the municipality of “Formosa do Rio Preto” - BA, and another part in the forests of Tocantins which borders the “Jalapão” and “Serra Gerais” state park. Throughout the study period, some practices related to soybean production were followed, such as the production of bioproducts (Trichoderma spp. and complex of bacteria of the genus Bacillus), plant stand evaluation, pest and disease monitoring, plant monitoring. The activities carried out helped to expand knowledge about the obstacles in soybean production, in addition to demonstrating the main problems of the region to seek ways to improve agricultural production. The knowledge passed on about the entire soybean production process was of great importance, showing how to obtain greater grain production potential.
