Corn Growth Stages and Development
The corn staging system divides development into vegetative (V) and reproductive (R) stages (Table 3). Subdivisions of the V stages are designated numerically as V1, V2, V3, etc. through V(n), where (n) represents the last leaf stage before VT for the specific hybrid under consideration. The first and last V stages are designated as VE (emergence) and VT (tasseling). The (n) will fluctuate with hybrid and environmental differences. The six subdivisions of the reproductive (R) stages are designated numerically with their common names.

| Vegetative Stages | Reproductive Stages |
| VE emergence | R1 Silking |
| V1 first leaf | R2 blister |
| V2 second leaf | R3 milk |
| V3 third leaf | R4 dough |
| R5 dent | |
| R6 physiological maturity |
V(n) nth leaf
