Bioinputs are natural products applied to crops that contribute to more sustainable agriculture by boosting yields and reducing environmental impacts. In Brazil, the use of bioinputs such as in soybean has been consolidated, but the expansion of on-farm bioinput production is currently initiating a new revolution. Furthermore, applications of bioinputs to cash crops in Brazil have shed light on the great potential of such growth-promoting microorganisms (GMPs) to improve nutrient uptake and increase productivity. This study explores the effect of the complementary inoculation with growth-promoting bacteria of post-emergence soybean, previously inoculated with spp. Five treatments with growth-promoting bacteria were evaluated: T1-Control (no inoculation); T2-; T3- and ; T4-, , and ; and T5- and . In comparison with the control, all treatments with growth-promoting bacteria of the genera , , , and , applied after soybean emergence, induced 4-7% higher grain yields. Co-inoculation with and (treatment T5) resulted in a higher 1000-grain weight, while , , and (treatment T4) increased the number of pods and shoot dry weight. Our conclusion is that bioinputs increase soybean productivity and make agriculture more sustainable and efficient.
生物投入物是应用于农作物的天然产品，通过提高产量和减少环境影响，有助于实现更可持续的农业。在巴西，大豆等生物投入物的使用已经得到巩固，但农场生物投入物生产的扩大目前正在引发一场新的革命。此外，巴西将生物投入物应用于经济作物，揭示了此类促生长微生物（GMPs）在改善养分吸收和提高生产力方面的巨大潜力。本研究探讨了在大豆出苗后与促生长细菌进行补充接种的效果，此前大豆已接种了 spp.。评估了五种促生长细菌处理：T1-对照（不接种）；T2- ；T3- 和 ；T4- 、 和 ；以及 T5- 和 。与对照相比，大豆出苗后施用的所有 、 、 、 属促生长细菌处理均使谷物产量提高了 4 - 7%。 与 共同接种（处理 T5）使千粒重更高，而 、 和 （处理 T4）增加了豆荚数量和地上部干重。我们的结论是，生物投入物提高了大豆生产力，使农业更具可持续性和效率。
