This study compared the effects of mechanical harvest and artificial drying on seed quality of soybeans having permeable (Dare) and impermeable (D-1) coats. Seed were harvested by combine and hand as soon as possible after maturity and after four additional weeks of field wearhering. Only the mechanically harvested seed from the first harvest were used for the drying studies. The standard germination, TZ, accelerated aging and physical damage tests were used to evaluate the effects of the treatments on seed quality. Combine harvest reduced but didn't eliminate hard seed, unex-pectedly had no effect upon viability, but resulted in reduced vigor ratings. The percent undamaged seed was higher for the D-1 seed at both harvest dates, despite the fact these seed were 5.2% lower in moisture than the Dare on the second harvest. Delayed harvest lowered viability and vigor ratings of the Dare seed, but only vigor ratings of the D-1. Artificial drying the D-1 seed increased hard seed content but had no other immediate effects on quality. There was some indication of a direct relationships between seed coat permeability and rate of moisture loss. The conclusions were: a. Combine harvest of seed with the impermeable seed coat characteristic will reduce hard seed content to agronomically acceptable levels only when the seed are near 11% moisture content. b. Seeds with the impermeable seed coat are less susceptible to physical damage than those with permeable coats, although, this difference may not be attributable to differences in seed coat permeability. c. A four week delay in combine harvest resulted in increased physical damage and decreased vigor in both seed types but did not result in decreased viability of seed with the impermeable seed coat characteristic. d. Seed having permeable seed coats germinated faster than those possessing the impermeable characteristic, however, this difference was reduced by the effects of mechanical harvest. e. Artificially drying high moisture soybean seed possessing the impermeable coat characteristic resulted in a significant increase in hard seed content.
