What Is Napier Grass?
Napier grass is a perennial tropical grass mainly grown for livestock fodder. It is known for producing large amounts of leafy biomass, making it one of the best fodder grasses for dairy farming in Kenya.
The grass is highly popular among zero-grazing farmers because it provides reliable feed throughout the year when properly managed.
The Napier grass scientific name is: Cenchrus purpureus
Previously, it was scientifically known as Pennisetum purpureum
Many agricultural publications and farmers in Kenya still use the older scientific name.
Local Name in Kenya
Napier grass is commonly called:
- Elephant grass
- Uganda grass
- Bana grass
- Odiambo grass (in some local regions)
Different Kenyan communities may have their own local names depending on the region.
Why Napier Grass Is Popular in Kenya
Napier grass farming in Kenya has increased rapidly because of:
- Rising dairy farming demand
- Need for affordable livestock feed
- High milk production benefits
- Fast regrowth after harvesting
- Ability to grow in many climatic zones
- Low maintenance costs
- Excellent silage production
Farmers in counties such as Kiambu, Nyeri, Murang’a, Uasin Gishu, Nakuru, Bungoma, Kakamega, Meru, and Nyandarua widely cultivate Napier grass.
Types of Napier Grass in Kenya
There are several Napier grass varieties grown in Kenya today.
1. Ordinary Napier Grass
This is the traditional variety grown by most small-scale farmers.
Features:
- High biomass production
- Good for cut-and-carry systems
- Requires moderate rainfall
- Susceptible to stunt disease
2. Super Napier Grass
This is an improved variety developed for higher yields and disease resistance.
Benefits
- Faster growth

- Softer stems for livestock digestion
- Higher milk production support
Super Napier is becoming increasingly popular among dairy farmers in Kenya because of its superior feeding quality.
3. Bana Grass
Bana grass is a hybrid Napier variety known for:
- Thick stems
- High biomass
- Excellent silage quality
4. Kakamega 1 & Kakamega 2
These are improved varieties developed for:
- Disease resistance
- Better yields
- Enhanced adaptability
Napier Grass Seeds
Many farmers search for Napier grass seeds, but Napier grass is mainly propagated using:
- Root splits
- Stem cuttings
- Cane cuttings
True Napier grass seeds are less common because vegetative propagation gives faster and more reliable establishment.
However, certified seed suppliers and agricultural research institutions sometimes provide hybrid Napier seeds.
How To Plant Napier Grass
Proper planting is essential for high yields.
Land Preparation
- Clear weeds thoroughly

- Harrow the soil to fine tilth
- Add manure before planting
Napier performs best in fertile, well-drained soils.
Climate Requirements
Napier grass grows well in:
- Warm tropical climates
- Areas receiving 750mm–2500mm rainfall annually
- Altitudes between 0 and 2400 meters
Soil Requirements
Best soil conditions:
- Fertile loam soils
- Good drainage
- Soil pH between 5.0 and 7.5
Planting Materials
Use:

- Roots split from disease-free plants
Avoid infected planting materials.
Spacing
Recommended spacing:
- 90cm × 60cm
- 1m × 1m for intensive management
Proper spacing improves air circulation and reduces disease spread.
Best Time To Plant Napier Grass in Kenya
The ideal planting season is:
- Beginning of long rains
- Beginning of short rains
This ensures enough moisture for establishment.
Fertilizer Requirements
For maximum yields:
- Apply farmyard manure during planting
- Top-dress with CAN or NPK fertilizer
- Add slurry regularly in zero-grazing units
Organic manure greatly improves biomass production.
Nutrient Content
One of the biggest reasons farmers grow Napier grass is its strong nutritional profile.
Napier Grass Nutrient Content Per Dry Matter

| Dry Matter | 18%–25% |
| Crude Fiber | 30%–35% |
| Energy | Moderate to High |
| Calcium | Good levels |
| Phosphorus | Moderate |
| Digestibility | High when young |
Young Napier grass contains more protein and is easier for livestock to digest.
Benefits of Napier Grass
