How to grow Boma Rodhes Grass

Rhodes grass is a vigorous, perennial grass, originating in South Africa, with a strong root system that gives it good drought tolerance. It spreads quickly, forming good ground cover, and grows to 1.5 m.

It grows under a wide range of conditions. It is useful in the cut-and-carry system and for open grazing and is popular for hay making. Common varieties are Giant, Boma , Mbarara and Masaba Rhodes.


  • does well in low rainfall areas (<900 mm) and is drought tolerant
  • withstands heavy grazing
  • is very palatable
  • is good for hay making


  • can be hard to establish because seed germination is poor
  • can be overgrazed because of its high palatability



Grows at altitudes from 600 m to 2000 m. It does well in areas receiving more than 250 mm rainfall annually and also persists well under drought conditions.


Grows in a wide range of soil conditions but performs best in loamy, fertile soils. It does not do well in alkaline or very acid soils. However you should first test your soil with before planting.

It is best grown as a pure stand.

Plough and repeat at least once to make a fine seedbed. Plough again when the weeds have emerged to reduce competition during establishment. Sow immediately after this ploughing.


Rhodes grass is usually established from seed but root splits can also be used. The best time to sow where there are two rainy seasons is during the short rains. Where there is one rainy season, plant from early to mid rains.

Sow when the soil is loose (dry). Make furrows 25 cm apart, using a peg to measure. Drill the seeds in the furrows, at a seed rate of 12 kg per hectare (2.5 acres). That means 1.2 kg will sow

0.1 ha or 1/4 acre. Cover the seeds lightly, for example by placing light tree branches over the furrows.

Apply fertilizer or manure during planting to promote strong root development. Recommended fertilizer are DAP at 1-2 bags/ha.For good results broadcast 10 ton/ha of manure and harrow before planting.

For high productivity, apply nitrogen fertilizer, preferably during heavy rains, at the rate of 100 kg per hectare.


Make sure the plot is weed free when it is first sown. Remove weeds between the rows using a hand hoe.


No diseases of importance but common pests such as armyworm may attack the pastures.


Start harvesting or grazing soon after grass flowers. If cutting, cut close to the ground to stimulate spreading. Leave to grow again until next flowering.

When well managed, Rhodes grass can yield an average of 8 tonnes dry matter per hectare per year.

Yields in the second year may be double those of the establishment year, but this also depends on management and environmental conditions.

Seed production

Seed can be harvested by hand with sickles and threshed with sticks. It is important to keep the seeding pasture clean of weeds because Rhodes grass seed is more difficult to clean than most other tropical grasses.

Rhodes grass often produces two crops of seed per year. Rhodes grass seed matures 23–25 days after flowering. Yields up to 350 kg seed per hectare can be harvested. Seed can remain viable in storage for up to 4 years.


Grazing is the most common method of feeding Rhodes grass. Avoid overgrazing— because its palatability is extremely high, livestock tend to overgraze pasture. Some farmers use the grass for cut-and-carry. It also makes good hay.
