Turnip

A cool-season brassica grown for its edible swollen root and greens. Root-zone moisture should be managed to support steady growth and usable harvest quality.

Brassica rapa Rapifera Group · root and leafy vegetable

Profile

Guidance 1: Grow in moist, well-drained soil.
Guidance 2: Insufficient water or delayed harvest can make roots woody.
Guidance 3: Flea beetles and caterpillars may feed on foliage.
Guidance 4: Clubroot, leaf spot and soft rot are reported problems.

Water & soil context

Moisture (VWC): No volumetric water-content target is documented in the cited species pages.

Drought tolerance: Crop-specific drought class is not documented in the cited pages.

Illustrative monitoring-depth band

6–12 in

Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.

Keep the active root zone from becoming excessively dry; water needs vary with soil, weather, and crop stage.

Problems to watch

Monitor for crop-specific pests and diseases; remove affected plant material and seek local diagnosis.

Stress signs

Wilting, yellowing, poor growth, or damaged foliage may indicate stress; diagnose in context.

Where you'll find it

Edible roots, bulbs, tubers, stems, leaves, or fruits as appropriate to the crop.
