The Question
What are the different growth stages of corn that I should be aware of when using the Flight App for Stand Counts?
The Answer
Corn growth stages are divided into vegetative (V) and reproductive (R) stages. 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.
VE (Emergence): The coleoptile breaks through the soil surface.
V1 (First Leaf): The first leaf has a visible leaf collar.
V2 (Second Leaf): Two leaves have visible leaf collars.
V3 (Third Leaf): Three leaves have visible leaf collars.
V(n): nth leaves have visible leaf collars.
VT: mature plant
