What is the spacing (row to row & plant to plant) of extra early varieties of cauliflower?
Show Hint
Remember: Small plant canopy (extra-early group) = close spacing ($45\text{ cm} \times 30\text{ cm}$). Large, spreading canopy (late-season/snowball group) = wide spacing ($60\text{ cm} \times 45\text{ cm}$).

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
In olericulture, planting spacing is determined by the growth habit, vegetative canopy, and maturity group of the vegetable crop.
Cauliflower (Brassica oleracea var. *botrytis*) varieties are grouped into extra-early, early, mid-season, and late-season cultivars.
Step 2: Detailed Explanation:
Let us analyze how canopy size dictates spacing across different cauliflower maturity groups:
- Extra-Early/Early Cauliflower Varieties: These cultivars (such as 'Pusa Katki' or 'Early Kunwari') have a rapid growth cycle, small plant stature, and narrow, upright leaves.
Because of their small vegetative canopy, they can be planted closely without causing inter-plant competition for light and nutrients.
The recommended commercial spacing is 45 cm between rows and 30 cm between plants (or $45\text{ cm} \times 45\text{ cm}$).
This high-density planting optimizes yield per unit area.
- Mid-Season and Late-Season Varieties: These cultivars (such as 'Pusa Snowball' or 'Snowball-16') grow slowly, produce massive, spreading foliar canopies, and form large curds.
They require wider spacing, typically 60 cm x 45 cm or 60 cm x 60 cm, to prevent crowding and disease outbreaks.
Therefore, the most suitable spacing for extra-early varieties is $45\text{ cm} \times 30\text{ cm}$.
Step 3: Final Answer:
The standard spacing for extra-early varieties of cauliflower is 45 cm x 30 cm.
In olericulture, planting spacing is determined by the growth habit, vegetative canopy, and maturity group of the vegetable crop.
Cauliflower (Brassica oleracea var. *botrytis*) varieties are grouped into extra-early, early, mid-season, and late-season cultivars.
