Abstract

Seed treatment is an essential practice to ensure the initial establishment and productive success of soybean (Glycine max L.) crops. This study aimed to evaluate the quality of soybean seeds, cultivar 80I82 RSF IPRO, subjected to seven treatments, including a control, using chemical (Fludioxonil + Metalaxyl-M) and biological agents (Bacillus aryabhattai; B. amyloliquefaciens; B. paralicheniformis; B. velezensis + B. amyloliquefaciens; Trichoderma harzianum), based on emergence tests. Two emergence tests were conducted, one in sand and the other in lowland soil, evaluating seedling emergence, emergence speed index (ESI), and vigor. The treatment with Fludioxonil + Metalaxyl-M showed a high germination rate (90%), high vigor (82%), and a lower incidence of abnormal seedlings (6%) in the soil emergence test. Under the same conditions, biological treatment with Bacillus amyloliquefaciens resulted in high germination (87%), high vigor (83%), and a low percentage of abnormal seedlings (5%). In contrast, treatment with Trichoderma harzianum was the least efficient, resulting in the lowest values in emergence tests, both in sand and soil. Seed treatment with Bacillus amyloliquefaciens demonstrated potential for use without negatively affecting the physiological quality of soybean seeds.
