It is considered a poor forage since it has high fibre and condensed tannin concentrations and is not readily eaten by stock. More suitable for small ruminants than for cattle.
Most commonly used in contour hedgerows for erosion control, often in association with Desmodium cinereum (formerly known as D. rensonii). Prunings are used for mulch (slow breakdown of leaf due to high concentration of condensed tannins) and green manure in alley cropping systems. It is also used to shade young coffee and cocoa plants, for weed suppression and soil enrichment in orchards, and to provide fuel wood and stakes for climbing crop species.
Pods provide a brilliant orange dye for silk. F. macrophylla is a host plant for Lac insects (Kerria lacca Hemiptera: Kerriidae) cultivation in India.
Will grow on most soils, with very low to moderate (and even high) fertility, with a pH range from 4 to 8, and high soluble aluminium (up to 80% saturation).
Requires a minimum annual rainfall of about 1,100 mm, and grows up to 3,500 mm. tolerating up to 6 months dry season. Capable of surviving on poorly drained and occasionally waterlogged soils.
Best growth between 22 and 28 ºC, producing minimal growth above 36 °C and below 12 °C. Found from sea level to 2,000 m asl.
Moderately shade tolerant.
Short day flowering response.
Plants grow vigorously once established, if adapted. Excellent coppicing and regrowth capacity after cutting, producing numerous shoots from buds near the base of the stem. Cut at intervals of 6‒14 weeks at 35‒100 cm above the ground. Cutting interval depends on climatic conditions.
Well established plants tolerate fire.
Guidelines for establishment and management of sown forages.
To improve germination, seeds should be soaked in boiled water for 2‒3 minutes, stirring the whole time, followed by soaking in cool water for 12 hours. Reasonable results being obtained from cool water soaking alone. Seedlings emerge in 7‒14 days. Scarification with concentrated sulphuric acid for 15 minutes is more effective than the hot water treatment, but is more hazardous to the operator. Planting density varies according to the use. For large areas, it can be planted in rows 90 cm apart with a seed planted every 10‒20 cm. For hedgerows, it is important to have minimal space between plants within the row if erosion control is to be effective. Weed control is necessary for 3‒6 months after emergence, since early growth is slow and young plants are sensitive to competition. Although somewhat promiscuous, best to inoculate seed with strains of Bradyrhizobium such as CB 756, CIAT 4203, or CIAT 4215.
Although adapted to infertile soils, limited fertilizer is beneficial. In Brazil, about 75 kg/ha/yr of biologically fixed nitrogen have been measured.
Seedlings are slow to develop and cannot compete with other species. Once established, plants are strongly perennial and can tolerate competition from companion species. Beneficial effect on trees is reported when Flemingia is used as mulch-providing plant such as in orchards. Can act as a trellis for twining legumes.
Grasses: Any grass once F. macrophylla becomes established.
Legumes: Twining, trellis-seeking species such as Centrosema spp.
Not susceptible to any major diseases. Can be used to reduce nematode populations of Pratylenchus spp., Helicotylenchus spp. and Rotylenchus spp., but not of Meloidogyne spp. Flemingia is an off-season host for the pigeonpea pod fly, Melanagromyza obtusa, which can reduce seed yields.
Spreads by seed only.
Considered to be low.
Lower leaf nutrient levels (especially K, Ca, and Mg) than Leucaena leucocephala and Gliricidia sepium (11.3‒24.4% CP; 0.15‒0.3% P; 1.0‒1.4% K; 0.13‒0.94% Ca; 0.2‒0.3% Mg). IVDMD values for foliage range from 11 to 60%, most values tending to be in the lower part of the range; in sheep, an apparent DM digestibility of 54% has been reported. Low IVDMD values result from high tannin and lignin levels in the leaves; depending on accession, concentrations of 0‒27% extractable condensed tannins and 17‒39% lignin have been reported.
Palatability is adversely affected by high tannin content of the leaves, immature leaves being considerably more palatable than mature herbage. Can be 'disguised' by mixing with grasses and other legumes. Under grazing and in mixture with other species, low palatability can lead to dominance of F. macrophylla. Palatability is very low in the wet season but reasonable in the dry season.
Detection of saponin has been reported.

Yields depends on growing conditions, and range from 3 to 12 t leaf DM/ha/yr, more commonly <8 t/ha.
Has been fed to lactating dairy goats for 120 days without harmful effects, although another report showed growth and milk production of goats decreased when Flemingia foliage supplied more than 15% of the dietary DM. Other studies report upper limits in the range of 7.5‒75% F. macrophylla in the diet of lactating goats.
2n = 22. There is a large germplasm collection available with considerable variation regarding important features.
Produces flowers and seed within 6‒7 months from planting, although first year seed yields are low. Pods are dehiscent, so need to be harvested regularly (twice per week handpicking of ripe pods) before the discharge of seeds. Cumulative yields of up to 200 kg/ha seed can be obtained. Pigeonpea pod fly (Melanagromyza obtusa) can reduce seed yields if active.
