| Factor | Recommendation | | :--- | :--- | | | 1.5–2.5 cm (light soils), 2.5–3 cm (heavy soils) | | Target plant stand | 60–100 plants per m² (oilseed) | | Critical error | Sowing too deep or into dry soil | | Indicator of good sowing | Uniform emergence within 4–8 days |

| Parameter | Oilseed / Field Crop | Microgreens | Home Garden | | :--- | :--- | :--- | :--- | | | 4–6 kg per hectare | 20–30 g per 1020 tray | 2–3 g per m² | | Row spacing | 25–45 cm | Not applicable (broadcast) | 15–20 cm | | Plant spacing (after thinning) | 10–15 cm | None | 10–15 cm | | Depth | 1.5–3 cm (no deeper than 4 cm) | Surface – 0.5 cm | 1 cm | | Method | Drill or broadcast + light harrow | Broadcast | Shallow furrow or broadcast |

Mustard is fast to germinate and robust, but success depends on shallow sowing (≤3 cm), adequate but not excessive moisture, and a fine seedbed. For oilseed, precise row spacing and weed control are critical; for cover crops, higher seed rates and timely incorporation matter most.

| Climate | Season | Typical Months (Northern Hemisphere) | | :--- | :--- | :--- | | Temperate (Oilseed) | Late summer – Autumn | Aug – Oct (winter crop) | | Cold/High Altitude | Spring | Mar – May (spring crop) | | Subtropical/Tropical | Cool dry season | Oct – Nov | | Green manure | Any frost-free period | Spring – early autumn |

| Problem | Cause | Remedy | | :--- | :--- | :--- | | Poor emergence | Sown too deep (>5 cm) | Re-sow at correct depth | | Damping-off | Wet, cold soil after sowing | Use fungicide-treated seed; delay sowing until warmer/drier | | Bird damage | Seeds left on surface | Cover with thin soil or use netting | | Uneven stand | Variable seed depth or cloddy seedbed | Improve seedbed preparation; calibrate drill |
