A study was conducted to determine the immediate effects of mechanical damage to soybean seed as influenced by a combine harvester applying different levels of threshing effort on pods and seed at different levels of moisture content. Four rows were harvested at a time, and the yield was 34 bushels per acre. A rasp bar cylinder type harvesting combine was used to harvest the seed at 16.85, 13.05 and 1.65% moisture content, applying Threshing Indices of 70, 87, 108 and 130. Visible effects of damage, evaluated as percentage of split seed, cracked coated seed, visibly uncracked seed and seed size, revealed that the interaction of seed moisture and Threshing Index was of significant importance in determining the degree of injury to seed at harvesting. For any level of one of these two factors, the extent of injury was dependent upon the level of the other factor, except for cracking of the seed coat, for which the interaction failed to be significant. Decreased levels of seed moisture content and increased cracking of seed coats, and a decrease in the proportion of visibly uncracked seed. Combine harvested seed tended to be smaller than hand harvested. Physiological responses of the combine harvested seed were evaluated by the standard germination test, accelerated aging test, storage under adverse conditions, and soil emergence. Seed harvested at 16.85% moisture produced lower germination percentages and lower vigor ratings than did seed harvested at 13.05 and 11.65% moisture. Increased Threshing Index caused a decrease ...
