The objetive of this work was evaluate three harvesting methods of sorghum seeds,
cv. Ag 2002, and the tests more indicated to evaluate physiological and health quality and mechanicaldamage. The treatments were: seeds harvested handly and dryed on sun, seeds harvested in radial and axial threshing system, both dryed on sun, and seeds harvested by gatherer with axial threshing system and dreyed artificialy. Half of the seeds were treated with fungicide. The physiological quality was evaluated by germination, field emergence, speed emergence index, accelerated aging and cold test; the determination of mechanical damage was made by the Iodine 2% and Amaranthus 0,1% tests and the seed health analysis was made by blotter-test method. The seed harvested by axial thresthing system showed best performance, being this method considered the best harvest method. The seeds harvested by radial threshing system showed lower germination and vigour, and higher incidence of mechanical damage. The more efficient tests to determinate physiological quality and to detect mechanical damage in seeds were accelerated aging and Amaranthus test, respectively.
