INFLUÊNCIA DO TRATAMENTO DE SEMENTES COM BIONEMATICIDAS EM CULTIVARES DE SOJA

Abstract

Soybean plays a key role in the agricultural sector, both in Brazil and globally. To improve productivity and sustainability in soybean cultivation, several techniques have been developed, including the use of bionematicides via seed treatment. This study aimed to evaluate the effect of two commercial bionematicides applied through seed treatment on the vegetative development and final productivity of soybean seedlings. The experiment was conducted at Fazenda Santa Lúcia – Franciosi, located in the municipality of São Desidério (BA), using the soybean cultivar 84I86RSF IPRO. The treatments consisted of: (1) seeds treated with Aveo EZ and (2) seeds treated with Nemat, each with ten replications. The following agronomic parameters were evaluated: root system length, leaf length, fresh and dry mass of roots, and fresh and dry mass of leaves. The data were subjected to analysis of variance and Tukey’s test at 5% significance. Results showed no significant differences between the treatments for root length, fresh root mass, fresh leaf mass, dry root mass, and dry leaf mass. However, the treatment with Nemat showed a significant effect 1% for the leaf length parameter. Regarding yield, the use of Aveo EZ resulted in 4,124.35 kg/ha, while the Nemat treatment yielded 3,807.10 kg/ha, representing an 8.33% difference between treatments.
