Grain sorghum [Sorghum bicolor (L.) Moench] can be stored as high-moisture grain when treated with propionic acid, but it is not known if grain tannin levels affect the amount of acid needed. We planned the investigation to answer this question and to determine the effects of storage temperature on the amount of propionic acid needed for storage of high-moisture grain sorghum. Grain from a high- and a low-tannin hybrid was stored with 0, 0.5, 1.0, and 1.5% (wet weight) propionic acid for 9 weeks to determine rates required for safe storage. Results showed that high-tannin grain does not require as much propionic acid (1.0%) for safe high-moisture storage as does low-tannin grain (1.5% propionic acid). Low-tannin grain was stored at low and high temperatures at the above propionic acid rates. Grain stored at the higher temperature spoiled at a faster rate, and results indicated that a higher rate of acid is needed for safe storage at higher temperatures
