Open-field broccoli

Brassica oleracea L. (Broccoli Group)

Growing broccoli in the open field requires maintaining a temperature range of 16–25°C and providing regular moisture. The crop is characterized by its ability to produce a secondary harvest and does not require shading of the heads.

In the reference 31 varieties crop Broccoli, where this is mentioned in the description.

When growing broccoli in the open field, the optimal temperature range for head formation is 16–25°C. Exceeding these values or other stress factors may trigger premature bolting. The crop is light-demanding and does not require shading of the heads, which distinguishes it from other types of cabbage.

The technology involves planting seedlings at the 5–6 leaf stage or direct seeding followed by thinning. Industrial planting density is 30–35 thousand plants per hectare. An important step is irrigation control, especially during the rosette formation and head development phases, as excess nitrogen in the late stages leads to excessive leaf mass at the expense of yield quality.
