Napier grass (also known as elephant grass) is one of the most valuable forage crops for livestock farmers in Namibia. It is widely used for feeding cattle, goats, and sheep because of its high biomass yield, drought tolerance compared to other grasses, and ability to regrow quickly after cutting.
In Namibia’s semi-arid to arid climate, selecting the right forage crop is critical. Napier grass stands out because it can survive under moderate water stress while still producing significant yields when properly managed. It is especially useful for farmers practicing zero-grazing or cut-and-carry systems.

Climate and Soil Requirements
Napier grass grows best in warm climates, making most regions of Namibia suitable, especially areas like the central highlands and northern regions. However, success depends on managing water and soil conditions properly.
- Temperature: Optimal growth occurs between 25°C and 35°C
- Rainfall: Requires at least 800 mm annually, but can still grow with less if irrigation is provided
- Soil Type: Prefers well-drained loamy soils but can tolerate sandy soils common in Namibia
- Soil pH: Best between 5.5 and 7.5
If you’re dealing with poor soils, don’t expect miracles. You’ll need to improve fertility, or your yields will stay low no matter what.
Land Preparation
Proper land preparation is where most beginners mess up. If you rush this step, your grass won’t establish well.
- Clear the land
Remove weeds, shrubs, and debris completely. - Plough the soil
Plough to a depth of 20–30 cm to loosen the soil and improve root penetration. - Harrowing
Break down large soil clods to create a fine seedbed. - Add manure or compost
Napier grass responds very well to organic matter. Apply well-decomposed manure before planting.

Planting Methods
Napier grass is not grown from seeds in most cases. It is propagated using:
- Stem cuttings (most common)
- Root splits (tillers)
Using Stem Cuttings
- Cut mature stems into pieces with 2–3 nodes
- Plant them at an angle or horizontally in the soil
- Ensure at least one node is buried underground
Spacing
- Row spacing: 75–100 cm
- Plant spacing: 50–100 cm
Proper spacing ensures enough sunlight, airflow, and nutrient availability.
Best Planting Time in Namibia
- Start planting at the beginning of the rainy season (November–January)
- If irrigation is available, planting can be done anytime

Water Management
Here’s the truth: Napier grass is not “water-free.” It’s just more forgiving than other crops.
- Rainfed areas: Rely on seasonal rains
- Irrigated areas: Water 2–3 times per week during dry periods
Avoid waterlogging, as it can cause root rot. In sandy soils (common in Namibia), water drains quickly, so you may need more frequent irrigation.
A simple drip irrigation system can dramatically improve growth and reduce water waste.
Fertilization
Napier grass is a heavy feeder. If you don’t feed it, it won’t feed your animals well.
Organic Fertilizer
- Apply kraal manure regularly (every 1–2 months)
- Improves soil structure and moisture retention
Chemical Fertilizer
- Use NPK fertilizers for faster growth
- Apply nitrogen-rich fertilizer after each harvest to encourage regrowth
A practical approach is combining both organic and chemical fertilizers for the best results.

Weed Control
Weeds compete for nutrients, water, and sunlight. If you ignore them early, they’ll choke your grass.
- Weed manually during the first 6–8 weeks
- Once established, Napier grass suppresses weeds naturally
- Mulching can also help reduce weed growth
Don’t rely on chemicals unless necessary—manual control is often enough and cheaper.
Pest and Disease Management
Napier grass is relatively hardy, but it’s not invincible.
Common Issues
- Stem borers
- Smut disease
- Leaf spots
Control Measures
- Use clean planting material
- Remove and destroy infected plants
- Maintain good spacing for airflow
- Rotate crops if disease becomes persistent
Healthy soil and proper management will prevent most problems before they start.
Harvesting Napier Grass
This is where you start seeing the payoff.
First Harvest
- Ready after 3–4 months
Subsequent Harvests
- Every 6–8 weeks
Cutting Height
- Cut at 5–10 cm above ground level
- Cutting too low weakens regrowth
If you wait too long to harvest, the grass becomes tough and less nutritious. Younger grass has higher protein content and is better for livestock.

Yield Expectations
Under good management in Namibia:
- 20–40 tons per hectare annually (rainfed)
- Up to 60–80 tons per hectare (irrigated and fertilized)
If your yields are far below this, something is wrong—usually water, soil fertility, or poor planting technique.
Feeding Livestock
Napier grass is highly nutritious when harvested at the right stage.
- Best for cattle (especially dairy cows)
- Suitable for goats and sheep when chopped
- Can be mixed with legumes for better protein balance
You can also:
- Make silage for dry seasons
- Store excess production for future use

Common Mistakes to Avoid
Let’s be honest—most failures come from avoidable mistakes:
- Planting in poor, unfertilized soil
- Not watering during dry periods
- Cutting too late (low nutritional value)
- Overcrowding plants
- Ignoring weed control early on
If you fix these, you’re already ahead of many farmers.
Profit Potential in Namibia
Napier grass isn’t just for feeding your animals—it can make you money.
- Sell fresh grass to nearby farmers
- Supply dairy farms
- Produce silage for commercial sale
With Namibia’s growing livestock sector, demand for quality feed is always there. If you do this right, it can become a steady income stream.
