“…Although not all applied bio-inoculants resulted in an increase in 100-seed weight, Biofix, Masterfix, Nitrofix, and NitroZam gave higher values than the control in Angonia. The a pplication of bio-inoculants in soybean has been reported to result in increased seed quality and weight that positively increases yield (Gitonga et al, 2011;Tavanti et al, 2020). On the other hand, environment and variety interaction affected 100-seed weight, seeds pod −1 , and pods plant −1 (Table 8).…”

Soybean production in sub-Saharan Africa is increasing as farmers open more land areas for cultivation and replace other crops, such as tobacco, in favor of this legume crop. Despite the production is increased in Mozambique, demand for animal feed and oil is not satisfied. As such, farmers explore ways to improve yield per unit area of soybean by using bio-inoculants from various sources and agroecological adaptability. These bio-inoculants are seldom available during planting time, and retail at almost similar prices although yield varied based on the product source, handling, and the rhizobia strain carrier. Mozambique does not produce bio-inoculants, so it obtains the product from neighboring countries or as far as the South American continent. In this study, we evaluated the performance, ecological adaptability, and soybean productivity of seven Bradyrhizobium diazoefficiens strain-based bio-inoculants from several countries with different carrier materials: Biofix, Masterfix, Nitrofix, NitroZam, N-Fixer, Soygro Peat, and Soygro Liquid against a control (non-inoculated) on two soybean varieties Storm and TGx 1904-6F. The trial was conducted in the 2016 and 2017 growing seasons in three agroecologies of Mozambique at Angonia, Nampula, and Ruace. Data on nodulation, plant growth, biomass nitrogen content at beginning of podding (R3) stage, yield, and yield components of soybean were evaluated. Analysis of variance and contrast comparisons were performed on the Statistical Analysis System® 9.4. Nodule weight per plant variedly increased from 7.7 to 167.6 mg with inoculation of both varieties across environments. Plant tissue nitrogen content at the R3 stage was higher in inoculated non-promiscuous variety at 3.9% than the promiscuous counterpart with 3.7%. Storm, a non-promiscuous short-maturity variety of soybean, responded to inoculation and accumulated more N than the medium-to-late maturity promiscuous TGx 1904-6F. Higher N tissue content is an indicator of better nutritive value, as well as high-quality recyclable biomass of inoculated soybean. Both Storm and TGx 1904-6F responded to all inoculants variedly with NitroZam yield of 2,750 kg ha−1 being highest, while Soygro Liquid was lowest with 2,051 kg ha−1 but more than the check with 1,690 kg ha−1 across sites. There were varietal differences in 100-seed weight after inoculation where Storm (15.4 g) had heavier seeds than TGx 1904-6F (13.1 g). The results show that inoculation improved plant growth and development, increased nodulation, and gave higher yields for better economic returns among farmers. Inoculation has the potential of increasing soybean yield, nutritive value, and biomass quality within Mozambique.

“…For example, under tropical conditions, Bacillus subtilis inoculation (strains Pant001 and QST713) associated with Bradyrhizobium japonicum has been reported to increase soybean [Glycine max (L.) Merr.] yield compared to single inoculation with B. japonicum, besides improving seed quality due to the increase in total storage proteins concentration, seedling emergence percentage and seed vigor (Tavanti et al, 2020). Traoré et al (2016) reported improved corn seed germination, plant growth, plant production (increase yield by 42%) grain and shoot P biomass content of 34 and 64%, respectively with B. subtilis inoculation (strain DSM10).…”

The use of plant growth promoting bacteria (PGPB) that can solubilize phosphorus (P) has shown potential to improve nutrient availability in grass crops such as corn (Zea mays L.) This study was developed to investigate if inoculation with Azospirillum brasilense, Bacillus subtilis or Pseudomonas fluorescens associated with P 2 O 5 rates can improve phosphorus use efficiency (PUE) reflecting on greater corn development and yield. The field trial was set up in a Rhodic Hapludox under no-till system under Savannah conditions, in a completely randomized block design with four replicates. Treatments were tested in a full factorial design and included: (i) five P 2 O 5 rates (0 to 105 kg ha −1) and (ii) four PGPB seed inoculation (Control-without inoculation, A. brasilense, B. subtilis or P. fluorescens). Inoculation was found to increase grain yield by 39.5, 29.1, and 15.9% when B. subtilis was inoculated in the absence of P 2 O 5 rates and associated with 17.5 and 70 kg P 2 O 5 ha −1 and by 34.7% when A. brasilense was inoculated with application of 105 kg P 2 O 5 ha −1. In addition, inoculation with B. subtilis and A. brasilense were found to increase P uptake, benefiting productive components development, leading to an improved PUE, and greater corn grain yield. The results of this study showed positive improvements in P uptake as a result of B. subtilis and A. brasilense inoculation, with an increase of 100.5 and 54.6% on PUE, respectively; while the P. fluorescens inoculation were less evident. Further research should be conducted under biotic or/and abiotic conditions such as attack of pathogens and insects, drought, salinity, water flooding, low and high temperature to better understand the role of PGPB, inoculated alone or in combination as the co-inoculated method.

“…Furthermore, the bacteria of this genus can be consider plant growth promoting rhizobacterium (PGPR), because they can colonize the rhizosphere and promote plant growth (KALAM et al, 2020;TAVANTI et al, 2020). Rhizobacteria are essential for nutrient recycling and have potential as biofertilizers (SANTOS et al, 2020) for productivity increment, besides being able to benefit the plant during periods of stress (PII et al, 2015).…”

The growth of the Brazilian market for biological defensive follows a worldwide trend of reducing the use of pesticides in crops, due to international and societal demands for a more sustainable agriculture. The objective of the present work was to evaluate the efficiency of Bacillus subtilis Bs10 as an inoculant for the soybean crop, through the promotion of plant growth and productive performance in the field. Three field experiments were conduct in the municipalities of Porto Nacional and Formoso do Araguaia, Tocantins, Brazil. The treatments used in the experiments were five doses of the B. subtilis Bs10-based product (0, 100, 200, 300 and 400 mL 50 kg of seeds-1), plus one treatment with a commercial B. subtilis-based product. The inoculation of B. subtilis Bs10 provided increases in biomass, agronomic characteristics, plant population and productivity in soybeans under field conditions. There were positive results starting at a dose of 200 mL, with gains in productivity ranging from 28 to 41% in relation to the absolute control treatment, without inoculation of B. subtilis, and from 11 to 42% in relation to the treatment with commercial product. The bio formulated B. subtilis Bs10 should be recommend as a plant growth promoting inoculant in soybean.
