“…However, there was no significant difference in relation to the treatment composed by inoculation with A. brasilense and thiamin on seed. This result can be a consequence of a negative interaction between the bacteria and the vitamins, as it was observed for sweet maize (VENDRUSCOLO et al, 2018), since the variation on thiamine content can be a signal against stress effect (GOYER, 2010).…”

“…These effects culminate in gains in the vegetative and reproductive development of different plant species (OERTLI, 1987;HENDAWY;EL-DIN, 2010;SOLTANI et al, 2014). In this sense, increases in the vegetative organs of the mustard crop were observed (VENDRUSCOLO et al, 2017), as well as yield increases for the sweet corn crop (VENDRUSCOLO et al, 2018).…”

New technologies are constantly being launched, however studies that point to the effects of their joint application are lacking. The objective of this study was to evaluate the effect of the isolated and joint use of Azospirillum brasilense inoculation and the application of thiamine, on seed or leaf, on the development of millet in two cycles. A randomized complete block design was used in five replicates. The treatments were composed of the isolated or combined inoculation with Azospirillum brasilense and the application of thiamine, on seed (10 ml kg -1 ) or leaf spray (10 ppm). The relative levels of chlorophyll a, b and total, plant height, number of shoots, fresh and dry mass production and dry matter index of plants were evaluated. In the first cycle, treatments were only effective for the relative chlorophyll contents, and in general, the treatment with isolated inoculation of A. brasilense stood out, differing significantly from the treatment with thiamin applied on seed. In the second cycle, there was significant effect of the treatments on the variables of plant height and number of shoots, in which a maximum height of 165 cm and production of 140 shoots m -2 with application of thiamin on seed and with the use of A. brasilense and thiamine applied on the leaf, respectively. Thus, it was concluded that inoculation with A. brasilense increases the relative chlorophyll content in millet during the first cycle. The joint use of inoculation with A. brasilense and the application of thiamine can be used as a strategy to increase the number of shoots.

“…Thus, in possession of the results, the vitamin potential for use in crops of economic interest is verified, as a low cost alternative and with the capacity to increase economic gains. This can be seen for the sweet corn crop, for which a positive effect of the application of thiamine on the production and consequently on the monetary return on the sale of the product was verified (28,29).…”

Objective. Evaluate the productivity, sweet maize plants characteristics, crude protein and economic indicators of the production of sweet maize silage inoculated with Azospirillum brasilense and thiamine as seed treatment (0; 15; 30; 45 mg kg-1). Material and Methods. Biometric characteristics, productivity, crude protein content were evaluated, and the total operational cost structure was used to determine the economic indexes of a productive cycle. Results. It was observed that treatments with isolated or combined application of A. brasilense and thiamine did not affect the plant height, stem diameter, fresh and dry mass productivity and crude protein contents of sweet maize plants. However, the inoculation with A. brasilense increased in 24.36%, 24.36%, 53.15% and 10.47%, the productivity of fresh matter, gross revenue, operating profit and the profitability index, respectively, compared to the control treatment. Even with different responses, all treatments resulted in positive profitability indices, indicating the appropriate economic return with this activity. Conclusions. It was concluded that A. brasilense and thiamine applied as seed treatment do not significantly affect sweet maize plants development and composition; treatments influenced the economical indexes, and the isolated application of A. brasilense resulted in higher earnings; thiamine isolated application as seed treatment can be used as an alternative for improvement of economical gains.

“…These bacteria can promote plant growth through physiological changes due to the release of hormones such as auxins and cytokinins that promote increased root growth (Zafar et al, 2012;Hungary et al, 2013). This genus of bacteria has been extensively studied in grass crops (Vendruscolo et al, 2018;Alvarez et al, 2019;Contardi et al, 2020;Silva Junior et al, 2021) with few results for legumes. In soybean crop (Zuffo et al, 2016) and bean cultivars conducted in the winter season (Gitti et al, 2012), no effects on grain yield were observed, although Schossler et al (2016) have obtained an increase in plant height and number of pods per common bean plant.…”

Beans are one of the most important crops in Brazil but still have a low yield. The use of technologies such as the application of biostimulants can provide greater yield for the crop. Thus, the work aimed to evaluate the effect of using Azospirillum brasilense and phytohormones on Jalo Precoce beans. The experiment was carried out in randomized blocks with nine treatments and four replications. The treatments consisted of a control, Stimulate (compound of phytohormones), and A. brasilense applied isolated or associated to the seeds or in a furrow. The plant height, stem diameter, shoot dry matter, number of pods per plant, number of grains per pod, the weight of grains per pod, and 100-grain weight were favored by A. brasilense and compound of phytohormones. The highest yield of Jalo Precoce beans (2218 kg ha-1) was obtained using the A. brasilense + phytohormone compound applied in the sowing furrow. The grain yield of Jalo Precoce beans showed a high positive correlation with the number of pods per plant and medium correlation with stem diameter and shoot dry matter.
