Vegetation Period — Chinese Cabbage

Brassica rapa L. subsp. pekinensis (Lour.) Hanelt

This is the time interval from the emergence of full seedlings to the attainment of technical maturity of the head. The duration of the period ranges from 25 to 90 days, depending on the variety and hybrid.

In the reference 36 varieties crop Napa cabbage, where this is mentioned in the description.

Chinese cabbage is an early-maturing crop whose ripening timelines determine the cultivation strategy. Early-maturing forms, which ripen in up to 60 days, are intended for early production and protected ground, while late-maturing heading forms require a longer period for crop formation.

Selecting a variety based on the duration of the vegetation period is critically important due to the plant's photoperiodic sensitivity. Since the crop is prone to bolting under long daylight hours, sowing dates are selected so that the active growth phase does not coincide with the peak of light intensity, which most often makes late-summer and autumn sowings preferable.

The intensive growth of the plant requires high availability of moisture and nutrients throughout the entire cycle. The duration of the vegetation period also determines the storage life of the produce: early-maturing varieties require prompt marketing, and harvesting must be carried out strictly according to schedule to avoid over-ripening and the opening of the head apex.
