How to Grow Turnip in Varanasi: Practical Farming Guide
Why grow turnip in and around Varanasi?
Turnip (Brassica rapa/Brassica napus types) is a quick, low-cost winter vegetable that fits well into smallholder rotations around Varanasi. It takes little land, matures fast, and can provide fresh cash in the rabi market window (cool season) when leafy greens and root vegetables fetch good prices.
Choose the right type
There are two practical categories for growers near Varanasi:
- Globe/field types — larger roots, kept for storage and market sale; good for bulk root production.
- Salad/baby types (oriental or Hakurei-type) — small, tender roots harvested early and sold as premium fresh produce.
For local conditions, pick varieties that are bred or selected for fast growth and tolerance to bolting under irregular cold spells. If you buy seed, ask the supplier about days-to-maturity and local performance; small packets of seed allow on-farm trials.
Best seasons and sowing windows
Varanasi has a subtropical climate. Two practical sowing windows work well:
- Primary (rabi): Sow in October–early November to harvest from December to February. This is the main, most reliable window.
- Secondary (late monsoon/early autumn): Sow in August–September on well-drained land if you avoid waterlogging. These crops need careful management of rainfall.
Soil, land preparation and pH
Turnips prefer well-drained sandy loam to loam soils. They do poorly in heavy, compacted clay that impedes root expansion. Soil pH 6.0–7.5 is ideal.
- Plough or rotavator to 15–20 cm depth to break clods and create a fine tilth for uniform root shape.
- Remove previous brassica residues to reduce pest and disease carryover; practice crop rotation (avoid brassicas-on-brassicas for at least 2–3 seasons).
- In heavy soils, create raised beds (10–15 cm) to improve drainage and root development.
Seed rate, spacing and sowing methods
Decide based on the market form you want:
- For bulk roots: 25–30 cm between rows and 10–15 cm in-row spacing. Seed rate around 2–3 kg/acre (or adjust to seed germination percentage).
- For baby turnips: narrower spacing, e.g. 15 cm between rows and 5–8 cm in-row, sowing denser and thinning once to keep small roots.
Sow seeds 1–2 cm deep in well-prepared beds. Seedlings emerge in 4–10 days depending on soil temperature and moisture. Thin to desired spacing at 2–3 true leaves.
Nutrient management (practical rates)
Turnip responds to balanced nutrition. A practical fertilizer plan per hectare for Varanasi conditions is roughly:
- Basal application: well-rotted farmyard manure 5–10 t/ha at land preparation.
- Recommended NPK: about 60–80 kg N, 30–40 kg P2O5, 30–40 kg K2O per hectare split between basal and topdressings.
- Apply half the nitrogen and full P and K at sowing; topdress the remaining N at 3–4 weeks after sowing.
Adjust these rates to your farm size (scale down to kg per 1,000 m²) and soil test results. Avoid excess nitrogen late in growth or roots will be soft and storage life will drop.
Irrigation and water management
Keep soil consistently moist but never waterlogged. Practical schedule for rabi crops:
- Irrigate immediately after sowing to ensure uniform germination.
- Maintain regular intervals every 7–12 days depending on temperature; increase frequency during dry, warm spells.
- Reduce watering a week before harvest to firm up roots and improve storage life.
Mulching with straw or leaves reduces evaporation and keeps roots cleaner for harvest.
Weed control and interculture
Young turnip plants are sensitive to weed competition. Mechanical and manual measures are effective and low-cost:
- First light weeding or hoeing at 10–15 days after sowing to remove broadleaf weeds.
- Second inter-row weeding at 25–30 days. Avoid root damage during hoeing.
- Use organic mulches to suppress weeds in small plots.
Pests and diseases — identification and practical control
Common problems around Varanasi and on-farm actions:
- Aphids: cause curling leaves and transmit viruses. Monitor early. Knock off with water sprays, use neem oil or insecticidal soap for small plots; use chemical insecticides only when threshold reached and follow label rates.
- Flea beetles: small shot-holes on leaves in seedlings. Protect seedlings with light row covers or seedling-stage sprays. Keep fields clean of weeds.
- Cutworms: cut plants at soil line. Remove surface trash and use light earthing-up to expose larvae; baiting or approved insecticides may be needed for severe infestations.
- Root rot and damping-off: caused by waterlogged soil or infected seedbeds. Ensure good drainage, use treated seed, and avoid replanting in contaminated soil.
- Clubroot and nematodes: appear as distorted roots and stunting. Practice rotation, liming acidic soils, and avoid planting brassicas in affected patches for several years.
Sanitation and crop rotation are the most cost‑effective long‑term measures.
Harvesting and yields
Days to harvest depend on variety and desired market size:
- Baby salad types: 30–45 days from sowing.
- Globe types for full roots: 50–90 days.
Harvest in the early morning when roots are firm. For market, trim tops to 2–3 cm to reduce moisture loss and make handling easier. Handle roots gently to avoid skin breaks which invite rot.
Post-harvest handling and marketing tips
- Cool quickly after harvest. If refrigeration isn’t available, store in shaded, ventilated, and humid conditions to reduce shrivelling.
- Sorting: remove damaged or cracked roots, grade by size. Buyers often pay a premium for uniform, unblemished roots.
- Value addition: offer washed-and-bunched baby turnips or roots with greens (if sold fresh) to urban retailers; greens are an additional product and increase returns.
- Market windows: aim for early rabi markets (December–January) when supplies of other vegetables are lower and prices are steadier.
Practical tips from growers
- Run small on-farm variety trials to learn which types suit your soil and buyer preferences before scaling up.
- Keep seed for a couple of seasons only from the best plants if you want to maintain an open-pollinated line; for consistent results use certified seed.
- Record inputs and harvest dates per bed — turnip is quick-growing and records help you judge best sowing windows and fertilizer rates for your farm.
Summary checklist
- Sow Oct–Nov for main rabi crop; consider Aug–Sep for a secondary crop on well-drained land.
- Prepare a fine seedbed, apply FYM and balanced NPK based on soil testing.
- Maintain even moisture, control weeds early, rotate crops to manage pests and diseases.
- Harvest based on size: 30–45 days for baby types, 50–90 days for full roots; cool quickly and sort for market.
With matching variety choice, good seedbed preparation and attention to irrigation and pest control, turnip can be a reliable, quick-return crop for smallholders around Varanasi.
