Mustard — Package of Practices
The main rabi oilseed — sow on time into cool weather, feed it well with sulphur, and time the aphid watch to flowering when colonies explode.
Overview
Mustard (with rapeseed) is the main cool-season rabi oilseed across northern India, grown for its pungent oil and meal.
It is very responsive to sulphur; timely sowing, balanced nutrition and a sharp aphid watch at flowering decide the yield.
Climate & season
Mustard needs cool, dry weather (about 10–25 °C).
- A rabi crop sown as temperatures fall.
- Sensitive to frost at flowering and to heat at maturity.
- Clear, cool weather favours oil filling.
Soil & land preparation
Best on a well-drained loam to sandy loam at pH 6.0–7.5.
- Prepare a fine, firm seedbed for the small seed.
- Mix in 8–10 t/ha farmyard manure.
- Ensure good drainage.
Choosing a type & seed
Choose mustard or rapeseed types suited to timely or late sowing. No specific cultivar is named here.
Seed rate
- About 4–6 kg/ha.
- Sow 2–3 cm deep (the seed is small).
- Thin to the right spacing after emergence.
Seed treatment
- Treat with a recommended fungicide against seedling and blight diseases.
- Use clean, graded seed.
Sowing & spacing
- Sow on time as the season cools.
- Keep rows 30–45 cm apart.
- Thin plants to 10–15 cm within the row.
- Sow shallow (2–3 cm) for an even stand.
- Gap-fill early to keep the population.
Nutrient management
Split the nitrogen between sowing and the first irrigation; above all, supply sulphur.
| Input | Dose | Notes |
|---|---|---|
| Farmyard manure | 8–10 t/ha | Basal |
| Nitrogen (N) split | 80–100 kg/ha | Half basal · half at first irrigation |
| Phosphorus (P₂O₅) | 40 kg/ha | Full basal |
| Potash (K₂O) | 40 kg/ha | Basal |
| Sulphur key | Apply at sowing | Raises yield & oil content |
Water management
One or two irrigations make a big difference where available.
- The most critical irrigation is pre-flowering (~30–35 days).
- A second at pod (siliqua) development helps fill seed.
- Avoid waterlogging.
Weed management
- Give one or two weedings with thinning in the first month.
- A recommended pre-emergence herbicide helps on weedy land.
- Keep early growth clean for a vigorous canopy.
Plant protection
| Problem | Type | Watch for | Manage |
|---|---|---|---|
| Mustard aphid | Pest | Dense colonies on shoots and pods at flowering | Monitor from flowering, neem, recommended insecticide at threshold |
| Painted bug | Pest | Bugs on seedlings and at maturity | Timely sowing; spot-treat if heavy |
| Sawfly | Pest | Slug-like larvae chewing seedling leaves | Handpick, recommended insecticide if severe |
| Alternaria blight | Disease | Dark concentric spots on leaves and pods | Clean seed, rotation, recommended fungicide |
| White rust | Disease | White pustules on leaves; swollen flower stalks | Tolerant types, rogue affected parts, fungicide |
| Downy mildew / Sclerotinia | Disease | Greyish growth; stem rot in cool damp spells | Spacing, drainage, fungicide if severe |
- Sow treated seed of a tolerant type on time.
- Scout for aphid from flowering — it builds up fast.
- Conserve natural enemies; act at the threshold.
- Spray only when needed, following the label.
Use crop-protection inputs responsibly
Read the label, use the recommended dose, wear protective gear while spraying, and strictly observe the pre-harvest (waiting) interval before picking — on crops harvested repeatedly this matters at every picking. Prefer cultural and biological methods first and spray only when monitoring shows it is needed.
Harvesting & yield
Harvest when the pods turn yellow and the seed is hard and brown — before the pods shatter, generally 110–140 days.
- Cut in the cool morning to reduce shattering; dry and thresh.
- Yields of about 1.5–2.5 t/ha are achievable.
