A large-scale, widespread soybean seed industry has developed since the early 1950"s in response to rapidly increasing demand. Primary emphasis during this period of rapid growth has necessarily been given to expansion of capacity. Only slight improvements have been made in quality of soybean seed offered in the market. Seed quality in soybeans is only moderately good, and periodically poor. Moderately good. Moderately good quality seed, however, are not satisfying the expectations of farmers, who are becoming increasingly aware of the importance of highquality seed for efficient, maximal production of soybeans. The most chronic seed quality problems in soybeans relate to germinability and vigor. Soybean seed are inherently short lived and structurally weak ascompared to other kings of seed. Substantial losses in germinability and vigor are caused by hot, dry weather during seed maturation, weathering from rainfall and warm temperatures during the harvest period andmechanical abuse during harvesting and handling operations. Productionof high quality soybean seed requires timely harvest fallowed by aeration and/or drying as necessary to reduce seed moisture content to 12% or lees, and careful combining and handling to minimize mechanical damage. Germination percentage is not a realible index of the stand and crop producing potential of soybean seed. Seed lots of good germinationbut low in vigor can and do perform poorly in field even under rether favoreble conditions. Therefore, useof vigor tests to suplement ...
