Applications of Trichoderma asperelloides in soybean production: a perspective based on bibliometric and experimental data

With the growing demand for more sustainable agricultural practices, the use of bioinputs has been gaining increasing prominence, especially in large-scale crops such as soybean [Glycine max (L.) Merrill]. Among the microorganisms that are attracting attention, Trichoderma asperelloides stands out not only for its potential in the biological control of diseases but also for its ability to support plant growth. This study was divided into two parts: the first is a bibliometric analysis to understand how T. asperelloides has been applied in agriculture, and the second is a field experiment to assess its effect as a growth promoter in soybeans. The bibliometric analysis revealed a significant increase in publications on this topic in recent years, with Brazil leading the research efforts. The field experiment yielded promising results: when 5 g of T. asperelloides was inoculated directly onto the seeds, a higher yield was achieved (4,486.2 kg ha-1), attributed to improved nodule formation and enhanced root system development. Statistical analyses indicated a positive relationship between root growth, nodule formation, and plant productivity. These findings reinforce the importance of T. asperelloides as a valuable ally in increasing soybean yields in a more sustainable and environmentally friendly manner. Thus, T. asperelloides emerges as a viable alternative, contributing to a more efficient agriculture that aligns with current environmental challenges and global food security needs.
