Corn Growth Stages

Corn growth stages are divided into vegetative (V) and reproductive (R), as outlined in Table 1. 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 number of leaves (n) will fluctuate with hybrid and environmental differences. The vegetative stages and six subdivisions of the reproductive stages are designated numerically with their common names.

Vegetative Stages Reproductive Stages
VE = emergence R1 = silking
V1 = first leaf collar R2 = blister
V2 = second leaf collar R3 = milk
V3 = third leaf collar R4 = dough
V(n) = nth leaf collar R5 = dent
VT = tasselling R6 = maturity
Growth stages of a corn plant VE - R6.
