Moisture Equilibrium Values for Several Grass and Legume Seeds1

  1. James F. Harrington2



The equilibrium moisture contents of seeds of 35 kinds of grasses and legumes were determined for the seed moisture range of 13 to 4%. In comparison with the mean equilibrium moisture values of all seeds tested, the correlation coefficients for every kind of seed tested are highly significant, with r values of .95 to .99. This shows that although a given kind of seed may have a higher or lower moisture content than another kind at a given relative humidity, all kinds of seed tested showed essentially parallel changes in moisture content with changes in relative humidity, at least in the seed moisture range of 13 to 4%. A method is given for using the data presented in forecasting the equilibrium moisture percentage that each kind of seed will reach in a mixture of seeds in a sealed container.
