Effects of harvest and processing on soya bean seed quality

Abstract

Harvest and processing of soya bean seed are of the crucial importance for maintenance of seed quality. Soya bean, as a plant species, is particularly susceptible to mechanical injuries in various types of seed handling. Seed quality of three soya bean cultivars of different maturity groups was observed over diverse methods of harvest and processing. The highest germination was detected after manual processing of soya bean seed. Differences over cultivars were grater than those over methods of harvest and processing. The lowest both, germination and tolerance to machine-operated harvest and processing, were detected in the cultivar Bosa.

Žetva i dorada semena soje su od presudnog značaja za očuvanje kvaliteta semena soje. Soja, kao biljna vrsta, je posebno osetljiva na mehaničke povrede pri različitim načinima manipulacije semenom. Proučavan je kvalitet semena tri sorte soje, različitih grupa zrenja u zavisnosti od načina žetve i dorade. Najbolja klijavost je konstatovana posle ručne dorade semena soje. Razlike između sorti su bile izraženije nego razlike između postupaka žetve i dorade. Sorta Bosa, sa najnižom klijavošću, je takođe pokazala da je i najosetljivija na mehanizovan postupak žetve i dorade u odnosu na druge dve proučavane sorte.
