The present work has been developed with the purpose of evaluating the efficiency of round-holed flat sieves on the classification of soybean seeds. Three different soybean cultivars were used, namely FMT Kaiabi, FMT Tucunaré e BRSMT Uirapuru, each one represented by twenty (20) lots. During seed processing, samples were collected in the classifier feeding entrance and in the classifier outlet. It have been used 5,0; 5,5; 6,0; 6,5 e 7,0 mm round-holed flat sieves. The seeds were tested the uniformity and retention in manual sieve, and it was determined the moisture content and a thousand seed weight. The analysis and interpretation of the results enables to conclude that: a) soybean seeds can be classified on round-holed flat sieves; b) the thousand seed weight increases proportionally to the size of the soybean seed; c) the soybean classification assures more confiability on the determination of the thousand seed weight.
