Delayed harvesting of maize may result in a high incidence of pest infestation. This is because when maize is left in the field for too long, it becomes more susceptible to attack by pests such as weevils, borers, and rodents. These pests can cause significant damage to the crop, leading to losses in yield and quality. Additionally, delayed harvesting may also lead to grain shattering, which can result in low seed viability and reduced yields. Furthermore, the longer maize is left in the field, the more likely it is to be exposed to adverse weather conditions, which can lead to yellow colouration of the grains and further reduce their quality.
