🌾 Technical Characters of Mustard

 

1. Botanical Characters

 

Family: Brassicaceae (Cruciferae)

 

Species commonly grown:

 

Brassica juncea (Indian/brown mustard)

 

Brassica nigra (black mustard)

 

Brassica alba (yellow/white mustard)

 

 

Life cycle: Annual (90–120 days)

 

Growth habit: Erect, branching herb

 

Root system: Taproot with secondary roots

 

Stem: Round, erect, sometimes with waxy coating

 

Leaves: Simple, lobed, alternate, rough surface, green to bluish-green

 

Flowers: Yellow, typical cruciferous (four petals, cross-shaped), self- and cross-pollinated (insects, especially bees)

 

Fruit (Silique): Long capsule (2–8 cm) with 10–20 seeds

 

Seeds: Small, round, yellow, brown, or black depending on species

2. Agronomic Characters

 

Season: Rabi crop in South Asia; cool-season in temperate zones

 

Optimum temperature: 15–25 °C (germination 5–10 °C)

 

Rainfall requirement: 350–500 mm (well-distributed)

 

Soil requirement: Well-drained loamy soil, pH 6–7.5

 

Plant height: 80–160 cm (variety-dependent)

 

Duration:

 

Early: 85–100 days

 

Medium: 110–120 days

 

 

Seed rate:

 

OP varieties: 4–5 kg/acre (10–12 kg/ha)

 

Hybrids: 2–3 kg/acre (5–7 kg/ha)

 

 

Spacing: 30 cm row × 10–15 cm plant

3. Yield Characters

 

Yield potential:

 

Local varieties: 1.2–2.0 t/ha

 

Hybrids: 2.5–3.5 t/ha

 

 

Oil content: 35–42%

 

Protein in seed meal: 35–40%

 

 

 

—

 

4. Quality Characters

 

Mustard oil composition:

 

Erucic acid: 30–50% (in traditional varieties; low in improved types)

 

Oleic acid: 15–20%

 

Linoleic acid: 15–20%

 

Linolenic acid: 8–12%

 

 

Glucosinolates: Present; cause pungency but limit meal use in livestock feed

 

Special compounds: Allyl isothiocyanate → sharp pungency in mustard oil & seeds

 

 

 

—

 

5. Stress & Disease Resistance

 

Tolerance: Moderately tolerant to drought & marginal soils

 

Major pests: Mustard aphid (Lipaphis erysimi), painted bug, sawfly

 

Major diseases: Alternaria blight, white rust, downy mildew, sclerotinia

 

Improved hybrids: Show better tolerance to drought, heat, and aphids

6. Economic & Industrial Characters

 

Uses:

 

Oil (cooking, pickles, frying, massage oil, industrial uses)

 

Seed meal (animal feed, organic fertilizer)

 

Greens (mustard leaves, “sarson ka saag”)

 

 

Byproducts: Biodiesel, lubricants, mustard powder (spices, condiments)

 

 

 

—

 

✅ In short: Mustard is a cool-season oilseed crop with high oil content (35–42%), protein-rich meal (35–40%), and adaptability to marginal soils, but requires careful management of aphids and fungal disease
