Dano mecânico latente em sementes de soja obtidas com colhedora equipada com auto regulagens de trilha, separação, limpeza e velocidade de operação

Abstract

The production and use of high-quality soybean seeds are crucial for achieving success in farming. For this, the harvest operation, which is one of the most critical phases of the entire seed production process, must be carried out using machines equipped with axial rotors, as they cause less damage to the seeds compared to machines with radial rotors, as shown in various studies. The present research aimed to evaluate the latent mechanical damage, germination and vigor of soybean seeds obtained by a harvester equipped with self-adjusting threshing, separation, cleaning and operating speed, carried out in the municipality of São Luiz Gonzaga, RS. The results demonstrated that the technology contributed to obtaining seeds with a higher probability and lower rate of latent mechanical damage, which can result in greater uniformity in plant emergence and development. Combine Advisor® represents an advanced tool for optimizing soybean harvesting and ensuring the production of high-quality seeds.
