Variety traits

Maturity group — Persian clover

Trifolium resupinatum L.

Classification of Persian clover varieties based on the requirement for growing degree days and the duration of the period from sowing to flowering.

In the reference 17 varieties crop Persian clover, where this is mentioned in the description.

For Persian clover, the maturity group is determined by the calendar duration of the growing season from sowing to the onset of flowering and the growing degree days (GDD) indicator. Early-maturing forms require approximately 1130 °C-days to reach the mowing stage, while late-maturing varieties require 2676 °C-days or more.

The calendar duration until the onset of flowering varies from 67–124 days for early varieties to 145–165 days for late ones. Choosing a maturity group allows agronomists to set up a forage production schedule, distributing the machinery workload and optimizing the mowing phase to maintain maximum protein content in the biomass.
