The vegetation period of oats lasts from emergence to wax ripeness of the grain and ranges from 55 to 130 days. It serves as a key indicator of early maturity and the adaptability of varieties to regional climatic conditions.

The duration of the vegetation period is assessed both in calendar days and in the sum of active temperatures above +10°C. Early-maturing varieties require 1000–1500°C, mid-maturing ones require 1350–1650°C, and late-maturing ones require 1500–1800°C. Classification by ripening terms varies from early-maturing forms (65–80 days) to late-maturing ones (80–103 days).
The duration of the period is determined by the genotype by 28–30% and by weather conditions by 60–64%. The first half of the vegetation period is sensitive to day length, shortening as one moves north, while the second half lengthens under excessive moisture. Early-maturing varieties allow for avoiding summer droughts and the critical impact of early autumn frosts.
