The growth point is still below ground level and at this early stage is heavily influenced by soil temperature. A low temperature can extend the time between leaf stages. Hail, wind or frost damage at this stage has little or no effect on either the growth tip or the eventual grain yield. But it can delay the growth period by a few days. Waterlogging when the tip is still below ground, especially when associated with a high temperature, can kill the plants and lead to significant stand loss. Weed control reduces competition from weeds for available light, water and nutrients. At an early stage, weeds are devastating and can reduce yield significantly. Good weed control in the early development stages contributes greatly to the success of a maize crop.
