Changes in the water content of maize varieties after physiological maturity

Changes in the water content of 22 maize varieties were investigated during the period between physiological maturity and harvesting. It was found that neither the grain moisture, the cob moisture, the moisture content of the internode below the ear nor the thousand-kernel mass changed to a statistically significant extent. No significant water uptake or drying in excess of random variation, sufficient to influence the choice of harvesting date, could be detected during the test period.Nevertheless, considerable differences were recorded between the varieties for the moisture contents in the cob and in the internode below the ear. These could be of economic importance in choosing varieties and harvesting dates. The differences between the varieties can be attributed to the diverse genetic backgrounds, suggesting that breeding could lead to the development of maize varieties with low grain moisture at harvest.
