“…The bioagents promoted an increase of 20 % in the number of pods per plant and 16 % in the number of grains per pod, concerning the bean plants not inoculated with bioagents. Similar results were found by Rocha et al (2021), who noticed that black bean plants inoculated with Azospirillum brasiliense showed an average increase of 25 % in the number of pods per plant and grains per pod, but without increased yield and 100-grain weight, while Santos et al (2022), in soybean plants, increased yield by 10.1 %, concerning the control, inoculating endophytic Trichoderma.…”

“…According to Rocha et al (2021), constant drought conditions after the flowering of common bean plants and non-healthy seed lots can greatly influence the results of grain yield and its components. This fact was also observed in this study, since water deficit interference occurred in the reproductive phase of the common bean plants in the three years of experiment.…”

RESUMOabout 1.4 million hectares, with an average grain yield of 1,010 kg ha -1 (Conab 2022). In the current agricultural context, management practices such as the use of bioagents and cover crops, which aim at the sustainability of agroecosystems, have been increasingly adopted, since they ensure the increase of grain yield, reduction of production costs and conservation of the environment (Rocha et al 2021).

The search for cultivation techniques that provide productive, social and environmental benefits to the agroecosystem is of great seriousness for the sustainable intensification of agriculture. This study aimed to determine the effect of crop cover crops on the soil attributes and development of bean plants treated with the consortium of bioagents Serratia marcencens + Trichoderma koningiopsis grown in the winter. The experiments were conducted for three crop seasons, in a randomized blocks design arranged in a 2 × 8 factorial scheme, with four replications. The treatments consisted of the combination of eight cover crops with two microbial treatments. The bioagents and the mix of cover crops, especially the treatment 2 (corn) and the mixes 3 (millet, Crotalaria ochroleuca, black oat, white oat, buckwheat and coracana grass) and 5 (black oat, buckwheat, millet, Piatã grass and C. Ocholeuca), provided significant increases in the soil chemical and biological quality, with increases in the contents of Ca, Mg, K, H + Al and organic matter, as well as in the main soil pathogens that affect the bean crop, concerning fallow. In addition, there was an increase in the number of pods per plant and grains per pod. The use of these technologies provided savings, if compared to the use of chemical fertilization.

“…(2021) also did not observe an effect from the application of mineral N in two common bean cultivars. Rocha et al (2021) found that the application of A. brasilense to black beans also did not provide a significant effect on M100. Foliar application of the phytohormone BRs did not provide an increase in the M100 of cowpea, presenting an average value of 29.48 g (Figure 4A).…”

Cowpea [Vigna unguiculata (L.) Walp.] is a legume of socioeconomic importance in the northern region of the country, however, its production requires high fertilizer costs, especially nitrogen fertilizers. The use of techniques with the potential to increase crop productivity, such as the application of plant regulators (brassinosteroids-BRs) and the use of nitrogen (N) are necessary. Thus, the objective of this work was to evaluate the vegetative and reproductive phases of cowpea (BR3-Tracuateua) in relation to the application of BRs, mineral nitrogen fertilization and inoculation with the bacterium Azospirillum brasilense. The research was carried out in the experimental area of the Federal Rural University of the Amazon, Campus Capitão Poço. An experimental design was used in randomized blocks, with three replications, in a 3 x 4 factorial scheme: three N supply conditions (Without N, with mineral N and with biological N) and foliar application of four doses of BRs (0, 15, 30 and 45nM). The growth and production variables were not significantly influenced by the application of BRs and the forms of N supply. However, M100 and productivity were increased by the supply of N, both mineral and biological. Therefore, inoculation with Azospirillum brasilense in cowpea cultivation becomes a viable practice, with the objective of supplying N to plants, replacing mineral nitrogen fertilization.

“…Glomerospore density can be affected by soil attributes (da Silva et al 2017;Vieira et al 2020) and vegetation (Turrini et al 2018). In the present study, soils in areas undergoing initial regeneration were classified as sandy (dos , which are generally characterized by low nutrient availability, low water retention capacity and low levels of organic matter (Rocha et al 2021). This type of soil favours sporulation and dissemination of AMF (Aker et al 2022), since it has larger porous spaces, also facilitating soil-root exchange through AMF (Vieira et al 2020).…”

The objective of this study was to determine the structure, diversity, composition and drivers of AMF communities in succession areas of Atlantic Forest. Soil and root samples were collected in three natural ecosystems (mature rainforests, early and late secondary forests) with three areas on each ecosystem. In total, 38 AMF taxa were identified in field samples and three more in trap cultures with a greater richness of Acaulospora and Glomus. Based on a richness estimator, 70% of the AMF species were identified. Highest rates of root colonization and number of glomerospores were recorded in the early secondary forest. AMF species diversity differed between early and late forests. The main drivers of AMF distribution were coarse and fine sand, silt, Al, P, Na, pH and base saturation. The greatest number of exclusive species was recorded in the mature rainforests. The distribution of AMF communities was influenced by different successional stages and some soil attributes.
