Maize at 29% moisture content (MC) was dried to 18% MC and maize at 29% and at 10% MC was blended to obtain 18% MC. These dried and blended samples were monitored for single kernel MC using 2 single kernel moisture meters and a single kernel oven drying method. Deterioration due to fungal growth during storage was estimated based on visual observation. The mean moisture contents of dried and blended 18% moisture maize based on the single kernel oven method were not significantly different for all sampling days (days 1, 3, 7 and 14). The s.d. of moisture content decreased over time for both dried and blended 18% MC maize samples. For the dried 18% MC maize, the s.d. was consistently low throughout the 14-day observation period. For the blended 18% MC maize sample, the s.d. for days 0 and 1 was significantly higher than for days 3, 7, 9 and 14. It appeared that moisture equilibration was attained at day 3. Evidence of fungal growth was observed to occur one day sooner for the maize blended to 18%

than for the maize dried to 18% MC.
