Abstract

Background and aims

Brazilian Cerrado soils have low phosphorus content, leading many farmers to frequently apply fertilizers. With respect to this, Trichoderma are fungi with traits that can improve the fertility and health of the soil and promote plant growth. In this study, native strains of Trichoderma (T. viride GT-8, T. reesei GT-31, and T. longibrachiatum GT-32) from the Brazilian Cerrado were characterized. The impact of their inoculation on soybean growth and grain yield was also assessed under two phosphate fertilization conditions: 400 and 200 kg ha⁻¹ of simple superphosphate (SPP). Two independent field experiments were conducted with the cultivars Nidera NS6601 IPRO and DM 69IX60RSF 12X RR2PRO. Leaf and rhizospheric soil samples were collected for biochemical analyses.

Results

The strains showed phosphate solubilization from fertilizers and exhibited other PGP traits. Inoculation of GT-32 on cv. Nidera NS6601 resulted in a 4.5% increase in grain yield under 200 kg ha⁻¹ of SPP. For the second cultivar, the use of GT-31 and GT-32 at 200 kg ha⁻¹ of SSP resulted in grain yield increases of 22.7% and 18.6%, respectively. Inoculated plants showed higher shoot dry weight, chlorophyll content, phenolic compounds, and antioxidant responses under both fertilization conditions. Furthermore, enzymatic activities were higher in the rhizospheric soil of plants inoculated with GT-31 and GT-32 strains.

Conclusion

These findings demonstrated the potential of the GT-31 and GT-32 strains to improve soybean growth and yield with reduced fertilizer use. Additionally, their use could offer a sustainable strategy for enhancing soil health and fertility in Brazilian Cerrado soils.

期刊介绍： Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
