Corn growth stages are indicated by the number of leaf collars on the stalk where leaf blades break away from the stalk, and by ear development after fertilization. V3 stage During the V3 stage, the growth point is still below ground level and at this early stage is heavily influenced by soil temperature. Corn growth stages with estimated calendar days and growing-degree units These tables illustrate that calendar days between corn growth stages often not only depends on years and environment; but also on the staging method used.
