5. Market demand

It’s advisable to consult with local agricultural extension officers or conduct small-scale trials to determine which variety performs best in your specific location.

Planting Cumin

Sowing Time

In Nigeria, the best time to sow cumin would typically be during the dry season, between October and February. This timing allows the crop to mature during periods of lower rainfall, reducing the risk of seed damage or disease.

Seed Treatment

Before sowing, treat the seeds with fungicides to protect against soil-borne diseases. A mixture of Thiram and carbendazim can be effective. Soak the seeds in water for 12–24 hours before sowing to improve germination.

Sowing Methods

Cumin can be sown using two primary methods:

1. Broadcasting: Seeds are scattered evenly across the prepared field and then lightly raked into the soil.
2. Line sowing: Seeds are planted in rows, typically 30-45 cm apart, with 10-15 cm between plants within the row.

Line sowing is generally preferred, as it allows for easier weeding and harvesting.

Seed Rate

The recommended seed rate for cumin is 12–15 kg per hectare. Use high-quality, certified seeds to ensure good germination and plant health.

Crop Management

Irrigation

While cumin is drought-tolerant, proper irrigation is crucial for optimal yield. The crop requires 4-5 irrigations throughout its growing cycle.

1. Pre-sowing irrigation
2. 30–35 days after sowing
3. At the flowering stage
4. During seed formation,
5. At the seed development stage

Avoid over-irrigation, as it can lead to fungal diseases and reduced yield.

Fertilisation

Cumin responds well to balanced fertilization. A general recommendation is:

• Nitrogen (N): 30–40 kg/ha
• Phosphorus (P2O5): 20–30 kg/ha
• Potassium (K2O): 20–30 kg/ha

Apply half of the nitrogen and full doses of phosphorus and potassium as a basal application before sowing. The remaining nitrogen should be applied as a top dressing 30–35 days after sowing.

Weed Management

Weed control is critical, especially during the early stages of growth. Methods include:

1. Manual weeding: effective but labour-intensive
2. Mulching helps suppress weed growth and conserve soil moisture.
3. Herbicides: Use pre-emergence herbicides like pendimethalin or post-emergence herbicides like oxyadiargyl, following local regulations and guidelines.

Intercropping

Cumin can be intercropped with other compatible crops to maximise land use and reduce risk. Potential intercropping partners in Nigeria could include:

1. Chickpeas
2. Mustard
3. Fennel
