Resumo

Soybean production accounts for approximately 43% of Brazil’s grain produce, worth over 81 million tons for the 2012- 2013 cropping season. The use of quality seeds is essential for a high-yield agriculture, since low quality seeds compromise plant standing and increase production costs due to reseeding. This will in turn reduce yields through delays on the establishment dates. Seed quality is affected by relative humidity levels, mechanical damage during harvest and processing, thermal damage during the drying process and the environmental conditions during storage that could foster insect and fungi damage. The climate in the state of Santa Catarina favors soybean seed production, and seed companies in general work with high levels of technology. This work is aimed at characterizing the physical and sanitary quality of soybean seeds produced by different companies at different locations throughout the state of Santa Catarina (municipalities of Xanxerê, Abelardo Luz, Campos Novos and Canoinhas). The physical purity, moisture level, sanitary quality and mechanical damage of soybean seeds were studied at three stages, i.e. reception at the seed processing unit, at the end of the processing process and before being marketed. Results pointed out at mechanical injury and cultivar mixture as the main issues concerning seed lot quality, and that soybean seeds produced in Santa Catarina show pathogen contamination, which emphasizes the need for seed treatment.
