“…Zahedi & Abbasi (2015) observed that the morphological characteristics of soybean plants improved under water stress. Naoe et al (2020) also found a positive response in the yield of soybean submitted to drought. However, there is a lack of concise data for the effects of plant-bacteria interaction on the chemical composition of beans.…”

“…The double (IM x I; IM x D; C x IM) and triple (IM x I x D; C x IM x I; C x IM x D) interactions, in which the inoculation methods were considered, did not affect the oil or protein content in the beans. According to Hungria et al (2013), Zahed & Abassi (2016) and Naoe et al (2020), co-inoculation improves the soybean agronomic characteristics and yield in adverse conditions such as drought. However, in the present study, the effects of this technique for increasing the soybean oil or protein content were not verified.…”

The soybean chemical composition is strongly influenced by genetic factors, as well as their interaction with the environment and management practices. Among the environmental factors, water deficit and temperature are those that most contribute to modify the chemical composition of beans, especially oil and protein contents. The present study aimed to assess the effects of co-inoculation with Azospirillum brasilense on soybean oil and protein contents. Two field experiments were carried out on different sowing dates. The design consisted of randomized blocks, in a split-split-plot arrangement, with four replications, including two irrigation depths (25 % and 100 % of the ETc), two inoculation methods [Bradyrhizobium japonicum (strains Semia 5079 and Semia 5080) and Azospirillum brasilense (strains AbV5 and AbV6 + Bradyrhizobium japonicum)] and two cultivars (ANTA 82 and TMG 132). The co-inoculation did not affect the oil and protein contents of beans for any of the assessed management conditions. The water deficit in the reproductive stage, combined with the sowing dates, altered the oil and protein contents in both the assessed cultivars, showing, respectively, a higher average protein and oil content in the beans for the cultivars TMG 132 and ANTA 82.

“…These results agree with those obtained by Barbosa et al (2011), Finoto et al (2017), and Carvalho et al (2021, who also observed the effects of high temperatures and water reductions in the increase of oil content in soybean grains. Naoe et al (2020), also had about the isolated and/or associated effect of low water availability and high temperatures on the oil content.…”

The lipid content in soybean grain can be influenced by environmental characteristics, pod positioning, and plant population. However, the objective is to evaluate the percentage of soybean lipids in different plant positions in populations of two crops, in the southern region of the state of ParÃ¡. In this sense, two tests were carried out, one in the agricultural year 2018/19 and the other in 2020/21, in ConceiÃ§Ã£o of the Araguaia-PA. The experimental design used in each assay was randomized blocks with three replications. The treatments were arranged in plots sub-sub-sub-Subdivided, being allocated in the plots six cultivars, in the subplots three sowing densities (10; 14; 18 seeds m-1) and the sub-sub-two plots sites in the plant (on top and in the bottom third). The characteristic studied was the percentage of lipids. Individual variance analysis was performed and, later, joint analysis of the assays was performed. The highest averages of lipid contents were obtained in the lower third of the plant, with emphasis on the cultivars Ultra 75i77 IPRO, in the density of 18 seeds m-1 (24.3% crop 1 and 24.1% in the crop 2). The densities influenced the results, showing significant differences between them and being the best density of (18 seeds m-1). When the grains were collected in the lower third of the plant, they showed the highest lipid contents. Crop 1 was affected by the high temperature followed by a water deficit in the grain filling phase, showing that in November in southern ParÃ¡ you can get summer in the R5.1.

“…The occurrence of lower water availability during the grain filling phase promotes changes in metabolic routes [22], reducing the number of grains per m 2 , the number of ears per m 2 [23], length of internodes, the storage capacity of sugars in the stem, in addition to resulting in thinner stems, smaller plants and smaller leaf area, which can impair the development of plants [24].…”

The cultivation of green corn has been increasingly important for small farmers, due to its economic and social importance, derived from consumption in natura in the form of green ears. Thus, the present work was carried out to study the behavior of corn cultivars, in the presence and absence of the bacterium Azospirillum brasilense, under different nitrogen doses, aiming at the productivity of green ears in cultivation under low latitude. Two trials were installed, one in the agricultural year 2019/20 and the other in the agricultural year 2020/21, in the central region of the State of Tocantins. The experimental design used in each assay was randomized blocks, with three replications. The treatments were arranged in subdivided plots, where treatments involving seed inoculation with the bacterium were allocated in the plots Azospirillum (C Az) and without inoculation of seeds (S Az), in the subplots five doses of nitrogen (00, 30, 60, 90 and 120 kg ha -1 N) and in the subplots eight maize cultivars. For each process (C Az and S Az), an adaptability and stability study were carried out using the Eberhart & Russell (1966) and environmental stratification by the method of Lin (1982), where the combination of each dose of N, in each assay and in each process (C Az e S Az) represented a distinct environment. There was a differential response of the cultivars between the processes with and without seed inoculation. Seed inoculation resulted in a higher increase in the productivity of green ears. The cultivar BRS-3046 and AG-1051 adapted to the environments. I. INTRODUCTIONThe corn (Zea mays L) has aroused great economic interest due to its nutritional properties, being used in human food, mainly in natura like green corn (roasted, baked, porridge, pamonha, bled and other), which has driven social, economic, and cultural development in small and medium-sized properties [1].To obtain a high productivity of corn, nitrogen fertilization is indispensable, since nitrogen is the mineral nutrient required in greater quantity by the crop, because it Vanderlan Carneiro Dias et al.
