| ESTABLISHMENT
AND UTILIZATION OF RHODES GRASS -
(CHLORIS GAYANA)
Preamble:
Rhodes grass is a prolific stoloniferous grass that
grows naturally in many parts of East, Central and
Southern Africa. It is extremely adaptable and can
be found growing successfully in many parts of the
world with wide range of climatic conditions. It is
one of the most important grasses in many parts of
Australia where it was introduced from South Africa
around the turn of this century.
Rhodes grass was also introduced to U.S.A in the
last century and was an important feed crop in the
then called Kings Ranch.
At present Rhodes grass finds its place in nearly
all Pasture Improvement Programmes in the entire African
continent. It shows great promise in Latin America
and is being developed for many Asiatic countries
and is of prime importance in some temperature climates
such as Japan where it is used as an annual forage
crop.
The varieties described in the following pages were
all introduced from various parts of East Africa and
further selection at Kenya Agricultural Research Institute
(KARI) has produced some fine lines which compare
favourable with any f the perhaps better known varieties
available internationally.
Rhodes grass has been the most important pasture
grass in Kenya. This is mainly because of ease of
establishment and management which characterizes it.
All Rhodes grass varieties produce large bulk of herbage,
which is eminently suitable for grazing, making hay
or silage. All the varieties of Rhodes grass are palatable
and readily eaten by livestock, goats and camels even
at the coarser stages when the quality of the feed
is low.
A good establishment of pasture leys ensures consistent
high milk production all the year round particularly
where optimum pasture management is practiced.
Pasture fields can be established anywhere on earth
as long as water is available and certified seed whose
purity and germination is known (quality seeds) is
initially used. "Sample this" - most people
would find it hard to believe that the largest Dairy
farm in the world is in Saudi Arabia. They might believe
the largest oil field, largest desert, but not the
largest dairy farm in the world!
It is therefore a miracle how a little water can
turn this remote desert into a breadbasket and milk
shed for the Middle-East.
Kenya exporters a substantial tonnage of pasture
seeds to the Gulf region and the performance has been
exceptionally good given the fact that most of the
soils in the region are saline and with high temperatures
and scarce water which characterises the entire region,
one can conclude that, species sold from Kenya to
the region are reliable for planned animal farming.
VARIETIES OF GRASS SEEDS FOUND IN KENYA
Kenya Seed Company is currently the sole producer
of grass seeds (Chlories Gayan) in Kenya. The company
has a historical base dating back to 1956 when the
first grass fields for trials were initiated. To date,
the company has excelled beyond all expectations in
production of different but similar grass varieties
suitable for countries within the tropical and subtropical
ecological zones. The company has several released
pasture seed varieties while several others are in
the pipeline or in selection stage awaiting official
release by Government Certifying Agency.
Some of the commonly used varieties in Kenya and
others countries e.g. Middle East, Japan etc are:
1. BOMA RHODES: (chloris gayana)
This is a variety which was selected from an older
variety called MASABA RHODES. The original material
was grown in Uganda many years ago and therefore Boma
is an Improved Variety with softer and excellent herbage.
The variety is slow growing and therefore suited to
lower stocking rate but has excellent herbage quality.
The variety tends to give better bottom (tillers)
and is drought tolerant.. The variety is widely spread
in medium altitudes and is a popular variety in the
Gulf Region.
2. ELMBA RHODES (chloris gayana)
Elmba Rhodes like its sister variety Boma Rhodes
from Uganda. It is a selection from Mbarara Rhodes
(Mbarara is a town in Uganda). It is stoloniferous
perennial and is tolerant to a wide range of adverse
climatic conditions but prefers light sandy soils.
This is a quick growing variety with excellent soft
herbage and has strong seeding vigour. Elmba Rhodes
is also becoming increasingly popular in the Gulf
region.
NB:
Mbarara and Masaba Rhodes are still in production
but in a bigger scale due to their inability to
produce soft and excellent herbage for higher returns
but they remain significantly important for their
natural tolerance to drought and other natural calamities
like high temperatures and saline soils. These two
varieties can still be produced successfully where
Boma and Elma Rhodes cannot thrive well. They have
been successfully grown in the Middle East and other
parts of Africa region.
3. COLOURED GUINEA (Panicum Colorutum)
This is a tufted perennial. In the early seedling
stage the variety tends to have wide curly leaves
with slightly wrinkled edges. It has a good herbage
quality. One of the advantages of Coloured Guinea
over other grasses is the ability to withstand severe
water-logging and in spite of establishment difficulties
it is one of the few grasses which will persist in
black cotton soils. The variety is moderately drought
tolerant and will thrive in a wide range of rainfall
regimes. It also remains green well into the dry weather.
4. NANDI SETERIA (Setaria Sphacelata)
This again is a tufted perennial which is one of
Kenya's original Commercial Lines and still remains
the most promising pasture species for the high altitude
and high rainfall areas. This variety has also shown
considerable promise in many other countries. Nasiwa
Seteria which is an improvement from Nandi Seteria
in now in production. Nandi Seteria is resistant to
frost and water-logging and will thrive where Rhodes
grasses would not be suitable.
5. NASIWA SETERIA (Seraria sphacelata)
This grass is an improvement of Nandi Seteria. It's
a tufted perennial suitable for the high altitude
and high rainfall areas.
This variety is resistant to frost and water-logging
and thrives well where Rhodes grass would not be suitable.
6. CONGO SIGNAL (Brachiaria ruziziensis)
It's a short, broad leafed perennial which forms
a thick mat of leaves mot more than 20-40 cm high.
The thick cover supports high stockings rates. This
variety does well in warm, wet climates. It requires
high fertility and moisture regimes & requires
high phosphate and nitrogen levels. It is a persistent
variety that has the ability to compete with natural
grasses. It can be utilized as lawn grass and for
erosion control measure.
