Variety traits
Sunflower growing season
Helianthus annuus L.
The time from full emergence to the onset of harvest maturity of seeds, measured in days and depending on the maturity group and the sum of active temperatures.
In the reference 678 varieties crop Sunflower, where this is mentioned in the description.
The duration of the sunflower growing season covers the period from full emergence to the stage of physiological maturity, determined by the darkening of seeds, the drying of heads, and a seed moisture content of 10–15%. Plant development is assessed by interphase periods in accordance with the international BBCH scale.
The crop is divided into maturity groups ranging from ultra-early (80–90 days) to mid-late (116–135 days or more). The biological requirement for the sum of active temperatures above +10°C correlates with the duration of the period: early-maturing varieties require about 2000°C, while mid-maturing varieties require about 2150°C.
The length of the growing season directly affects yield: varieties with a longer formation period are potentially more productive but require a greater amount of heat. Proper selection of a maturity group allows agronomists to optimize crop rotation and avoid the impact of drought or frost.
