The exchange of technologies used in field cultivation for hydroponic systems can potentially increase plant development and grain production, requiring studies to verify the best management forms, such as growth-promoting bacteria and biostimulant compounds. With this in mind, the study aimed to evaluate the effect of the application of thiamine and niacin, alone and combined, to soybean plants in the absence and presence of inoculation with on the agronomic and physiological characteristics of the crop grown in an ebb and flow hydroponic system. Eight treatments were evaluated using -test (LSD) and Tukey's test, both at 5% probability ( < 0.05), in addition to Pearson correlation and canonical variables. The treatments consist of inoculation with at 1 mL 500 g seeds (with and without) and foliar application of four solutions (water, niacin (0.1 g·L), thiamine (0.1 g·L), and niacin + thiamine (0.05 g·L + 0.05 g·L)). We found that inoculation significantly improved the parameters evaluated and resulted in a gain of approximately 84.8% in yield when compared by -test ( < 0.05). In addition, the action of the vitamins was more significant when they were applied without the presence of , especially niacin, either alone or combined with thiamine, which increased yield parameters in this condition, identified when the Tukey's test ( < 0.05) was applied. We conclude that inoculation with in soybean seeds grown in a hydroponic system significantly benefits the development and grain yield, mainly when combined with vitamin solutions. Niacin also has the potential to be used alone or combined with thiamine in noninoculated or inoculated hydroponic soybean crops, respectively.
将用于田间种植的技术应用于水培系统可能会促进植物生长和提高谷物产量，这需要开展研究以验证最佳管理方式，例如使用促生长细菌和生物刺激素化合物。考虑到这一点，本研究旨在评估在潮汐流营养液栽培系统中，单独或组合施用硫胺素和烟酸，以及在接种和未接种[具体微生物名称缺失]的情况下，对大豆植株农艺和生理特性的影响。采用t检验（最小显著差数法）和Tukey检验对8种处理进行评估，显著性水平均为5%（P < 0.05），此外还进行了Pearson相关性分析和典型变量分析。处理包括以1 mL/500 g种子的量接种[具体微生物名称缺失]（接种和未接种），以及叶面喷施四种溶液（水、烟酸（0.1 g·L）、硫胺素（0.1 g·L）和烟酸 + 硫胺素（0.05 g·L + 0.05 g·L））。我们发现，通过t检验（P < 0.05）比较，接种显著改善了所评估的参数，产量提高了约84.8%。此外，在未接种[具体微生物名称缺失]的情况下施用维生素时，其作用更为显著，尤其是烟酸，单独或与硫胺素组合使用时，在这种情况下产量参数增加，这是在应用Tukey检验（P < 0.05）时确定的。我们得出结论，在水培系统中种植的大豆种子接种[具体微生物名称缺失]对其生长发育和谷物产量有显著益处，尤其是与维生素溶液组合使用时。烟酸也有可能分别用于未接种或接种的水培大豆作物，单独使用或与硫胺素组合使用。
