Axonopus fissifolius Raddi Kuhlm. It forms dense mats that are cm high but the flowering culms may reach cm. The general habit is erect and branching. The stems root at the nodes FAO, ; Cook et al. The leaves are cm long and mm broad, flat or folded, glabrous or sparsely hairy on the lower face. The slender inflorescences bear spike-like racemes, which are cm long.
The spikelets are about 2 mm long, alternatively arranged on the rachis Bogdan, wffinis Carpet grass is usually grazed rather than used in cut-and-carry systems, due to its slow growth and poor yields.
It is valued as a cover crop and turf grass in moist, low fertility soils FAO, ; Cook et al. Some commercial cultivars exist Campbell et al. It generally grows in low, flat or hilly humid and sub-humid areas of warm temperate or tropical woodland and savannahs FAO, ; Cook et al. It survives heavy frost during winter and has some tolerance of drought but does not grow well under flooding or waterlogged conditions Cook et al.
It prefers moist acid sandy soils, or sandy loamy soils. It becomes chlorotic on soils with pH above 7. Carpet grass is mainly found in permanent pastures where it can be heavily grazed by livestock or frequently cut. It can be vegetatively propagated through runners or sown, as it seeds easily FAO, ; Cook et al.
When it is sown Axonopus fissifolius can be broadcast on a well-prepared seedbed and then rolled in FAO, It can be sown with other grasses Axonopus compressusPaspalum dilatatumCynodon dactylonand Setaria sphacelata or legumes Aeschynomene falcataAeschynomene villosaArachis glabrataArachis pintoiLotus uliginosusTrifolium repensTrifolium semipilosumVigna parkeri FAO, ; Cook et al.
When sown with dallis grass Paspalum dilatatum or Bermuda grass Cynodon dactylon in low fertility soilsAxonopus fissifolius may gradually become invasive FAO, Additional N in such mixed stands prevents carpet grass from becoming invasive and also helps maintaining it in its vegetative stage with a higher nutritive value. In natural rangelands, carpet grass is readily propagated by grazing ruminants because of the high viability of its seeds after passing through the rumen and total digestive tract Simao Neto et al.
Carpet grass tended to be more abundant in sheep and beef cattle pastures than in dairy pasture Campbell et al. Defoliation by cutting or heavy grazing prevents flowering and the subsequent decrease in its nutritive value FAO, ; Cook et al.
Carpet grass is not suitable for hay and silage or for stand-over or deferred feeding because of its low productivity and poor nutritional value after the stems have flowered FAO, ; Cook et al.
In the USA, carpet grass is often referred to as a good cover crop and soil erosion controller for shaded sloping fields.
Carpetgrass (Axonopus affinis)
It is much valued in shaded orchards of Hawaii Smith et al. It improves soil structure, and increases water infiltration rates and soil water capacity Smith et al. Once established, carpet grass smothers out weeds with its dense sward growth habit, making it a good tool for reduced, or no chemical weed control Smith et al.
Carpet grass is considered a low quality forage Campbell et al. When leafy, carpet grass is fairly palatable to ruminants but palatability declines as the stands flower FAO, In Angus steers fed mature carpet grass hay in pens, DM intake reached Horses are reported to eat the clumps of seed-heads that are unpalatable to ruminants FAO, ; Cook et al.
