Stem elongation
A crop growth stage characterized by the rapid vertical growth of the stem and the formation of nodes above the soil surface.

Stem elongation occurs immediately following the tillering phase. During this period, the plant shifts its energy toward developing reproductive structures and increasing biomass. Nitrogen management during stem elongation is essential to ensure maximum potential for grain set and overall yield, as the crop's nutrient demand increases significantly.
Field management requires careful timing of applications, including plant growth regulators to prevent lodging in high-yield environments. A common mistake is late-season herbicide application, which can negatively impact the developing ear or panicle. Farmers should closely monitor growth stages to optimize the application of chemical inputs and avoid yield penalties.
