Chemistry On a zero moisture basis 4-week cut Malaysia Germplasm Reported from the Middle American Center of Diversity, carpetgrass or cvs thereof is reported to tolerate heavy soil, low pH, poor soil, and sand.
According to Bogdan , A. Widely distributed now in cut-over timber areas and the like. Warm-season grass, well adapted to sandy or sandy-loam soils with readily available moisture. Also adapted to light textured soils with moisture near the surface in humid tropical and subtropical climates. Drought resistance poor. Thrives under lower fertility levels than do most other pasture grasses adapted to southeastern United States.
Does not withstand prolonged flooding or permanent swampy conditions. Most commonly found on slightly acid sandy soils, with pH 5. Adapted also to clays, mucks and peats. Cultivation Produces abundant seed which germinate and spread quickly over areas where adapted. Establishes itself readily. Also reproduces by stolons. Production is low unless it gets adequate fertilizer, but fertilization is not profitable on all sites. Usually it is not fertilized as it is considered a poor-soil grass.
On very poor soils, it responds to lime, phosphorus, nitrogen and potassium, the quantities used depending on the soil. Responds well to manuring. It does not respond as efficiently to lime and fertilizers as most other southern forage grasses.
However, yields of carpetgrass in Florida have been doubled by use of complete fertilizer applications. Carpetgrass does not occur naturally with legumes.
When planted with legumes, such as Kobe lespedeza, white clover and Dutch white clover, yields are increased and quality of forage is improved. When grown in pure stands, carpetgrass is considered of inferior nutritive value, but can be enhanced by close grazing, application of fertilizer and presence of associated legumes. Unfortunately, carpetgrass tends to crowd out Dallisgrass and legumes. Harvesting Carpetgrass can be grazed all year by livestock.
It is a managed pasture grass in some localities. In Florida it remains green year round; elsewhere, it becomes dormant early in fall and begins growth in spring. A decumbent sod-former, it is very tolerant of frequent defoliation. Even extreme close grazing does not completely defoliate it, as leaves and shoots assume a horizontal position, encouraging new leaf-shoots to develop.
Close and frequent grazing stimulates vegetative growth, higher protein content and better yields. Although carpetgrass lacks feed value, it supplements southern range grazing in summer and fall when range grasses are tough and unpalatable, thus adding considerably to the forage resources of the South.
However, Bogdan notes that in mixed stand with other low-growing grasses, A. Biotic Factors Following fungi have been reported on Carpetgrass: Cerebellaandropogonis, Balansia strangulans, Curvularia lunata, Dinemasporium graminum var.
It is also parasitized by Striga asiatica lutea. Nematodes isolated from carpetgrass include: Meloidogyne sp. References Bogdan, A. Tropical pasture and fodder plants. Longman, London. Duke, J.

The terminal inflorescence, with two rows of alternating spikelets, is also a distinguishing feature. It has often been introduced deliberately, for use as a lawn grass, but it is now classed as a weed in at least nine countries Holm et al. It has a similar growth habit and inflorescence but may be distinguished by its glabrous nodes hairy in A. Prevention and Control Top of page Due to the variable regulations around de registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control.
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, Carpet grass is usually grazed rather than used in cut-and-carry systems, due to its slow growth and poor yields.
