Seed corn drying experiments
1929
Harrison, C.M. | Wright, A.H.
To insure good seed corn in Wisconsin, drying with heated air is necessary. Ear corn when dried by forced warm air ventilation at temperatures of 40 degrees to 45 degrees C was not injured. Corn dried at 50 degrees C was considerably damaged, and corn dried at 60 degrees C was nearly all killed. Corn dried at 70 degrees C was completely killed. Seed corn dried to less than 10% moisture at non-harmful temperatures was not injured either in germination, seedling growth, or field performance. No damage resulted when the seed corn was dried to as low as 4% moisture. When non-harmful temperatures were used, seed corn was not damaged regardless of the rapidity of drying. Corn dried to 12% moisture or less in 72 to 96 hours at temperatures of 40 degrees to 45 degrees C was not injured in germination, seedling growth, or field performance.
