The increase in productivity observed by these authors is explained by the deficiency of Co and Mo in soils where the experiments were performed.…”

Cobalt (Co) and molybdenum (Mo) are vital nutrients for biological fixation and nitrogen assimilation by soybean. This study aimed to evaluate the increase of Co and Mo contents in soybean seeds by leaf applications. The experiment was carried out in a seed production field in a 3 × 3 factorial scheme with three Co and Mo doses and three treatments (times). Each treatment consisted of two application times: R3+R5.1 (T1), R3+R5.4 (T2), and R5.1+R5.4 (T3). Doses were 0, 400, and 600 g.ha−1 of Mo and 0, 40, and 60 g.ha−1 of Co. No difference was observed for productivity, one thousand-seed weight, and germination. An interaction was observed between dose and application time in the Mo content. The application of 400 g ha−1 of Mo in T1 (R3+R5.1) provided a higher Mo content in the seeds (13.5 g.kg−1), which is 1350% higher when compared to the control. For Co, there was a difference only for doses, and the application of 40 or 60 g.ha−1 of Co increased seed nutrient content by 30%. Therefore, a higher enrichment of Co and Mo was observed in seeds with applications of 40 and 400 g.ha−1, respectively, applied in R3+R5.1.

“…Growth regulators applied during the first stages of plant development result in increased root growth, resulting in faster recovery following drought stress; higher resistance to insects, pests, diseases and nematodes; and faster and uniform plant establishment. These effects lead to increased plant nutrient uptake and therefore plant production [18].…”

“…The use of organic products with or without the addition of minerals has a sustainable and economically viable connotation for the producer. Several studies detail the importance of Bradyrhizobium for soybeans (SATURNO et al, 2017), of A. brasilense for grasses, and sometimes for soybeans (GALINdO et al, 2017;SOUZA et al, 2019;BOLETA et al, 2020) and the use of Co and Mo for several crops, including soybean (LANA, et al, 2009;GALdINO et al, 2020). However, there are few studies that address the use of this triple association in soybean crop, and the results are not always conclusive (GALINdO et al, 2017;TEIXEIRA et al, 2017).…”

Bradyrhizobium and Azospirillumco-inoculation associated with cobalt and molybdenum application in the soybean crop

Co-inoculation between bacteria of the genera Bradyrhizobium and Azospirillum can enhance the nodulation and promote the development of the soybean [Glycine max (L.) Merrill] root system, contributing to the increase in grain yield, in addition to the reduction in production costs and contamination of natural resources. Cobalt (Co) and molybdenum (Mo) use can also favor biological nitrogen fixation. The research evaluated the co-inoculation effect of bacteria associated with the Co and Mo application in soybean crop. The randomized blocks design was employed, in a 2 x 6 factorial scheme, presence and absence of Co and Mo and five ways of using the products Bradyrhizobium and Azospirillum, plus control, with four replications. The treatments were formed by the control (not inoculated + 20 kg N ha-1); seed inoculation with Bradyrhizobium (100 mL ha-1) + 20 kg N ha-1; seed inoculation with Bradyrhizobium (100 mL ha-1) and three treatments applying Bradyrhizobium + Azospirillum in furrow, in different doses. Height of insertion of the first pod, total number of pods and grains per plant, weight of 100 grains and grain yield were evaluated. Inoculation of Bradyrhizobiumjaponicum associated with co-inoculation of Azospirillumbrasilense via foliar and Co and Mo, provided increases in the number of pods per plant, number of grains per pod and weight of 100 grains, reflecting increases in grain yield.The use of Co and Mo, on average, increased soybean yield by 10%, resulting in an average yield of 4,904 kg ha-1.

Cobalt and molybdenum concentrated suspension for soybean seed treatment

Abstract: The concentrated suspension (CS), the basis of Mo trioxide, allows high Mo concentrations and is therefore a technical advance for seed treatment, since it allows the recommendation of the Mo at lower dosage than with the liquid solution formulations (LS).
