Morphological description

A fine to robust stoloniferous perennial, mostly with rhizomes.  Rhizomes can penetrate 40-50 cm in clay soil and 70-80 cm in sand.  Foliage dense, 10-40 cm tall (rarely to 90 cm);  leaf blades glabrous or sparsely pubescent, often glaucous, with minutely scabrous margins, 3-15 cm long and 2-4 mm wide;  ligule a dense row of short hairs on a membranous rim, 0.2 mm long with tuft of longer hairs either end (cf. membranous ligule in Digitaria).  Inflorescence a digitate panicle, comprising (2-) 4-5 (-7) racemes (in robust forms up to 10 racemes, sometimes in 2 whorls), 1.5-8 cm long.  Spikelets 2-3 mm long;  caryopses ovoid , about 1.5 mm long, yellow to reddish;  3-4.5 million seeds/kg.

Distribution

Var. dactylon is believed to have originated in Turkey and Pakistan, but has been introduced to all tropical and subtropical, and some temperate regions of the world.
Other varieties are native to one or more of the following:
Africa:  Angola, Mozambique, Namibia, South Africa, Tanzania, Zambia, Zimbabwe.
Asia:  Afghanistan, India, Israel, Sri Lanka.
Indian Ocean:  Madagascar.
Grows in grassland, lawns and pastures and as a weed in cultivation.  Locally dominant along roadsides and overgrazed and trampled areas.

Uses/applications

Used in permanent pastures for grazing or cut-and-carry, and for hay or pellets and silage production.  Provides useful standover or deferred feed.  Valuable for soil conservation, as a turf, and as a cover crop in orchards.

Ecology

Soil requirements

Grows on a wide range of soils, but best in relatively fertile, well-drained soils.  Adapted over a broad range of soil pH (4.5-8.5), but grows best when the pH is above 5.5.  Good tolerance of salinity, but makes only slow growth under saline conditions (maximum yields up to EC 7 mmhos/cm), 50% of maximum at 15 mmhos/cm, and nil at 22.5 mmhos/cm (1 mmho/cm = 1 dS/m).  Can use irrigation water with salinity up to 10.8 dS/cm for plants growing in sand, to 6.1 dS/cm in loam, and to 3.6 dS/cm in clay< /A > .  Generally not tolerant of high aluminium saturation, although some varieties appear more tolerant than others.

Moisture

Top

Usually occurs over an average annual rainfall range of 625-1,750 mm, but down to 550 mm, and up to 4,300 mm.  Very drought tolerant by virtue of rhizome survival through drought-induced dormancy over periods of up to 7 months.  Tolerates at least several weeks of deep flooding.

Temperature

Widely distributed from >50ºN in Europe to 34.5ºS in South Africa, and probably further south outside its native range.  It also grows from sea level over much of this latitudinal range to about 4,000 m asl in the Himalayas.  This equates to a range in average annual temperature from about 6-28°C.  There are large differences among ecotypes in terms of temperature response.  However, C. dactylon generally grows best with mean daily temperatures above 24°C or over an optimal range of 17-35°C.  Grows very slowly at 15°C.  Plants become dormant when night temperatures fall below 0°C, or the average daytime temperature below 10ºC, or cooler than a regime of an 8-hour day at 15°C and a 16-hour night at 5°C.  Although foliage and stems are usually killed at temperatures of -2 to -3°C, plants regrow rapidly from rhizomes with the onset of warm conditions.

Light

C. dactylon is not shade tolerant and yields decrease rapidly with increasing shade.  It usually dies out under medium to dense shade.

Reproductive development

Flowers throughout the growing season .  Wind pollinated.

Defoliation

Extremely tolerant of heavy grazing, but more productive if correctly managed.  Regular grazing and nitrogen fertilisation are necessary to maintain quality.  Cut for hay or silage when 30-40 cm tall or every 4-6 weeks, usually when in full bloom.  4 cuttings per year are possible.  A stubble height of 5-10 cm under grazing or cutting gives good regrowth and maintains sward density.  Renovate by ploughing or discing when sod-bound.

Fire

Top

It will stand severe fires due to the extensive rhizome development in most varieties and cultivars.

Agronomy

Establishment

Propagated by seed or vegetatively (turfs or stolon/rhizome pieces (sprigs).  Normally sown at 5-10 kg/ha dehulled seed, the higher rate being used for more rapid cover.  No seed dormancy has been reported.  Seed is best sown onto a very well prepared, fine, weed-free seedbed and rolled in.  Seedlings usually root down quickly.  Improved varieties are usually planted vegetatively due to low seed set or to avoid genetic drift.  Turfs or sprigs can be planted at 3.5-7 m³/ha (40-80 bu/ac) or on a 90 cm (or less) grid, into a roughly or well-prepared seedbed, but rolling is still essential.  Machinery has been developed to facilitate harvesting and planting of sprigs.  Seedlings and sprig-plantings grow vigorously once established.

Fertiliser

Survives at low fertility possibly due to non-symbiotic N fixation in the rhizosphere , measured at 30 kg/ha N in a 100-day period.  Responds well to improved fertility, with applications of a minimum of 10 kg/ha/month N and up to 60 kg/ha/month N necessary for moderate to high productivity, particularly in some of the improved hybrids.

Compatibility (with other species)

C. dactylon is very competitive, particularly in fertile soils, and only aggressive legumes are capable of forming an association with it.  It suppresses weeds well if kept mown or grazed closely and fertilised.

Companion species

Top

Grasses:  Generally not planted with other grasses.
Legumes:  Arachis glabrata , A. pintoi , Desmodium heterocarpon subsp. ovalifolium, Kumerowia (Lespedeza) striata, Neonotonia wightii , Stylosanthes humilis , Teramnus labialis , Trifolium incarnatum, T. repens, Vicia villosa.

Pests and diseases

Rust (Puccinia graminis) and Helminthosporium leafspot are the major fungal diseases of Cynodon dactylon , although resistant types are available.  Other fungal diseases include Bipolaris, Gaeumannomyces, Leptosphaeria, Marasmius, and tar spot (Phyllachora).  Smuts from Sporisorium, Sorosporium and Ustilago can infest seedheads.  Also attacked by the bacterium Xanthomonas cynodontis, and by barley yellow dwarf virus, lucerne dwarf virus, and viral stripe diseases (which affect corn and rice), as well as by a range of nematodes, the main one being root knot nematode (Meloidogyne spp.).  Selection for nematode resistance has been important in breeding programs.
Armyworm (Spodoptera spp.), tropical grass webworm (Herpetogramma licarsisalis), spittlebug (Prosapia bicinata) and bermudagrass mite (Eriophes cynodoniensis) are major pests.  The parasitic flowering plants Cuscuta pentagona, Nuytsia floribunda, Striga harmonithica, and S. lutea can adversely affect stands.

Ability to spread

C. dactylon spreads rapidly by rhizomes and stolons, and also by seed.  It can spread over 2 m/month during the growing season, a single plant forming a dense sward up to 25 m across in 2.5 years.

Weed potential

It is difficult to eradicate with chemicals or cultivation, and can become a serious weed in cultivated land.  Declared weed in over 80 countries.

Feeding value

Nutritive value

Top

Crude protein varies with age of material and level of nitrogen fertilisation, from about 3 to 9% in old grass, to about 20% in young, well-fertilised grassIVDMD varies from 40 to 69% with genotype.

Palatability/acceptability

It is very palatable if kept short in growth and fertilized.  Excellent grazing for village geese, ducks, goats, cattle and buffaloes if not trampled too much by these latter heavy beasts.  The rhizomes are given to horses.

Toxicity

Some varieties have the potential to produce high levels of prussic or hydrocyanic acid (HCN), especially when high levels of nitrogen are applied.  However, instances of prussic acid poisoning in cattle grazing C. dactylon are rare.  Although levels of total oxalate of >1% of the DM have been recorded, there is no experience of detrimental effects on grazing cattle. Frosted C. dactylon can cause photosensitization .

Production potential

Dry matter

Productivity depends on the cultivar used, the time of year and the amount of nitrogen available.  DM yields of 1,000-3,000 kg/ha per month are possible in summer and 100-1,200 kg/ha in winter.  'Coastal' yields up to twice as much as most common ecotypes.  Annual DM yields are generally of the order of 5-15 t/ha.

Animal production

Top

Liveweight gain of cattle ranges from 200-300 (-500) kg/ha/yr, or over 700 g/hd/day, when moderate rates of N and other fertilisers are applied and at stocking rate of about 2 or more beasts/ha.  Silage made from heavily fertilized, properly ensiled young grass can produce as much milk as corn silage and at a cheaper cost.

Genetics/breeding

Commonly 2n = 18, 36;  also 2n = 27, 30, 40.

  • var. dactylon (2n = 36)
  • var. aridus (2n = 18)
  • var. afghanicus (2n = 18, 36)
  • var. coursii (2n = 36)
  • var. elegans (2n = 36)
  • var. polevansii (2n = 36)

Cynodon dactylon is wind-pollinated, and generally self-incompatible, suffering from inbreeding depression when genotypes are self-pollinated. Quantitative traits such as seed yield and forage yield can be dramatically negatively affected.  Breeding programs have traditionally selected for DM yield, digestibility, disease and nematode resistance, and winter hardiness, and are now seeking to increase aluminium tolerance.

Seed production

Strains show considerable variation with respect to seed set, and in general, seed production is relatively low.  One or two crops per season - mid- and late growing season .  The crop is mowed into windrows, picked up and threshed by combines.  Seed yields may range from about 100 kg/ha to as high as 350 kg/ha.

Herbicide effects

Herbicides that can be used to control Cynodon dactylon include the aryloxyphenoxy-propionates (fenoxaprop-P-ethyl, haloxyfop, propa-quizafop, quizalofop-P-ethyl), dinitroanilines (endimethalin, prodiamine, trifluralin), glyphosate, 2,4-D, 2,2-DPA, clomazone, and sulfonylureas (imazapyr, sulfometuron, and thiazopyr).  Sulfometuron and metribuzin are more effective than thiazopyr and imazapyr, and glyphosate gives variable results.

Strengths

  • Palatable.
  • High nutritive value when young.
  • Excellent ground cover for soil conservation .
  • Tolerant of heavy grazing.
  • Makes useful hay and silage .

'NK37' or 'Giant' USA (1972) A giant, diploid seeding type.  Root knot nematode resistant.  Selected for arid environment.  Susceptible to Helminthosporium leaf spot.  In more humid environments, tends to be productive for a short time after establishment and then has declined rapidly in yield.  Distinguished from common types by its greater vigour and lack of pubescence.
'Oklan' USA Selected for good forage quality (high digestibility).  Less winter-hardy than 'Hardie' or 'Midland', and starting growth later in spring than 'Midland'.  Propagated by stolons.
'Russell' Alabama, Louisiana, USA (1994) Vegetatively propagated variety that appeared in a field originally planted to 'Callie' in Russell County, Alabama.  Resembles the common type in many respects, producing both rhizomes and stolons, forming a dense sod that holds up well under grazing and being especially effective in preventing erosion.  Strikes more readily from clippings, gives higher yields, spreads more rapidly, and is more winter-hardy than 'Coastal'.  Forage quality similar to that of 'Coastal'.
'Suwannee' Georgia, USA (1953) F1 hybrid between 'Tift' and a tall-growing introduction from South Africa.  Similar to 'Coastal', although more erect, producing more open sod (and therefore less weed resistant), less tolerant of close grazing, but more drought-resistant and superior in productivity and efficiency of nutrient and water use on deep sands.  Better adapted to soils of low fertility than 'Coastal'.  Used for grazing and hay .
'Tift' Georgia, USA Discovered by J.L. Stephens in old cotton patch near Tifton, Georgia in 1929.  Has long decumbent stems, few seed-heads and an abundance of large stolons and rhizomes.  Superior to common types for both hay and pasture .
'Tifton 44' Georgia, USA (1978) F1 hybrid between 'Coastal' and a naturalised accession from Berlin, Germany.  Lower growing, with finer stems, more rhizomes, and denser sod than 'Coastal'.  More resistant to leaf diseases than 'Midland'.  Starts growth a little earlier in spring, and is more winter-hardy than 'Coastal'.  More productive and more digestible giving 15-20% higher average daily liveweight gains during summer than 'Coastal', but slower to establish, seldom providing any significant forage production during the establishment year.  Used for grazing and hay .
'Tifton 68' Georgia, USA (1984) F1 hybrid between the two most digestible accessions in a collection of 500 introductions, PI 255450 from Kiboko, Kenya, and PI 293606 from Nairobi, Kenya.  Selected for rapid spread and high production.  Giant type with large stems, long stolons, and no rhizomes.  Spreads rapidly when planted vegetatively.  Higher production, digestibility, and average daily gain than 'Coastal', but is not very winter hardy.  Used for grazing and hay .
'Tifton 78' Georgia, USA (1984) F1 hybrid between 'Callie' and 'Tifton 44'.  Selected for ease of establishment, rapid spread, and early growth.  Taller, more stoloniferous (spreading more rapidly), establishes more readily, starts growth earlier and has better forage quality than 'Coastal'.  Similar in spread, establishment, and growth habit to 'Callie', but produces more rhizomes, is more winter-hardy, and resistant to rust.  Can produce 25% more dry matter, with 7% higher digestibility, leading to a 36% overall improvement in liveweight performance over 'Coastal'.  Not as winter hardy as 'Tifton 44'.  Used for grazing and hay .
'Tifton 85' Georgia, USA (1991) F1 hybrid from cross between PI 290884 from South Africa and 'Tifton 68'.  Selected for increased dry-matter yield and improved forage digestibility.  It is taller, has larger stems, broader leaves, and a darker green colour than most other hybrids.  Has large rhizomes (though fewer than 'Coastal' and 'Tifton 44') and very large, rapidly spreading stolons.  Can produce 26% more dry matter with 11% higher digestibility than 'Coastal'.  Not very winter-hardy.  Used for grazing and hay .
