APRIMORAMENTO TECNOLÓGICO NO TESTE DE EMERGÊNCIA DE SEMENTES DE SOJA EM LEITO DE AREIA

Abstract

Agribusiness plays an important role in the Brazilian economy with a significant representation in the GNP composition. Inserted in this context, there is the soy production chain that contributed significantly to this GNP formation. Given the importance of this chain, the market has been continuously seeking for new technologies in order to optimize the production processes and, as a result, obtain greater productivity and quality of the seeds produced, thereby increasing its profitability. Seed quality is an extremely important aspect, with the adoption of technologies and biotechnology as a way of ensuring a high-quality seeds production. Companies with good seed production programs are able to offer the product on dispatch with germination above 90% and vigor not less than 80%. As a way of evaluating these parameters, the germination test on a paper roll in the laboratory with fully controlled environmental conditions is applied and, in a complementary way, the emergency test of soybean seeds in sand bed without environmental conditions control. The responsibility by tests application rests with the Seed Quality Control department, which must perform them during the production process, guaranteeing the seed quality, as well as providing information to assist in the seed industries process decision as well for the producer, a security before the planting, so it is important that the response time is as short as possible. In view of the above, the present work aims to develop and evaluate the effectiveness of implementing technological instruments in a seed analysis laboratory greenhouse and to evaluate the impact of reducing the soybean seed emergency test response in sand bed. The methodology developed was divided into 6 phases, namely: planning, informational design, conceptual design, detailed design, preparation for production and validation. As a result, a viable device was obtained both for technical and economic aspects and, which provided a 50% reduction in the soybean seed emergency test in sand bed turning this study an important reference for this technology implementation in future studies.
