Morphological description

A slow-growing, succulent, segmented cactus, up to 5‒7 m high with a crown of over 3 m in diameter; with age developing a trunk up to 1 m diameter; superficially spreading root system.  Branches (cladodes) are flattened, obovate to oblong, 20‒60 cm long × 10‒40 cm wide, grey to grey-green; terminal cladodes always bright green, producing flowers and new growth; younger branches arching upwards.  Leaves are generally reduced to few spines (to 2.5 cm long) on young cladodes and shed early; some varieties are spineless.  Flowers located on the perimeter of the cladodes, conspicuous, yellow or orange, cup-shaped, 6‒7 cm long × 5‒7 cm wide; petaloids spreading, obovate to oblong-obovate, 2.5-3.5 × 1.5-2 cm, margin entire or erose, apex rounded, truncate, mucronate, or emarginate.  The fruit is an oblong berry, 5‒10 cm long × 4‒9 cm wide, green at first ripening to yellow, orange, red or purple in colour (variety dependent), covered with clusters of minute spines.  Number of viable seeds per fruit varies from 177 to 357.

Note: Cultivated O. ficus-indica forms are generally spineless, referred to by some as "var. inermis" or "forma Inermis". However, this is not a stable feature; formation of spines can be environmentally influenced.

Uses/applications
Forage

O. ficus-indica is used for feeding various classes of livestock, including dairy cattle.  In low rainfall countries it is a valuable source of energy and often water, although protein levels are low.  It can provide up to 180 t H2O/ha/yr stored in its tissue for livestock watering. 

Environment

It is used in alley-cropping systems, in contour hedgerows for soil erosion control,  and in rows as a windbreak. It can be used for land reclamation by virtue of its ease of establishment on degraded lands, and can improve soil fertility through cycling of nutrients and organic matter accumulation.

Other

O. ficus-indica is the most widespread and most commercially important cactus, and has been/is being widely introduced as a commercial fruit and vegetable (nopalitos) crop, more recently as part of forestry or agroforestry projects in developing countries. The thorny varieties are often used as defensive hedges.  It is also one of the cactus hosts for the cochineal insect (Dactylopius coccus Homoptera: Dactylopiidae) used in the production of cochineal dyes.

Ecology

O. ficus-indica is native to regions with a sub-tropical to warm temperate climate typically with summer rains and cool and dry winters. It is naturalized and cultivated throughout the arid and semi-arid zones of the tropics and subtropics, including warm-temperate climates.

Soil requirements

Requires well-drained soils (with <15‒20% clay content); adapted to a wide pH range; highest potential on fertile soils; able to grow on shallow and rocky substrates due to superficially spreading root system; no tolerance of salinity.

Moisture

Grows in an annual rainfall range of (150‒) 250‒800 (‒1,200) mm with 5‒8 dry months. Adaptation to low rainfall is partly due to the CAM (Crassulacean acid metabolism) photosynthetic pathway. Water use efficiency is 3‒5 times higher than in C4 and C3 plants.

Temperature

Grows in regions with hot summers (mean maximum temperatures of 35‒38 °C in the hottest month) and cool winters (mean minimum temperatures of 7‒12 °C in the coldest month); survives <0 °C for brief duration. Nights should be cold.

Light

No shade tolerance.

Reproductive development

Flowering occurs on 1‒2 yr-old cladodes.  Reproduction is both sexual and vegetative; 10.9‒18.5% of apomixis have been reported.  For plantations, O. ficus-indica is vegetatively propagated (cladodes as propagative material).  Plantations are exploitable after 3‒4 years and fully grown after 7‒10 years; can remain productive for >50 years under rational management.

Defoliation

Management (e.g. in terms of residual photosynthetic area after cutting) is necessary for sustainable production; depending on input level, harvests every 1‒4 years possible.

Fire

Fire is used as one of the tools to control stands of O. ficus-indica if the species is becoming invasive.

Agronomy

Guidelines for establishment and management of sown forages.

Establishment

O. ficus-indica is, in general, vegetatively established (cladodes as propagative material).  For rehabilitation/improvement of native rangeland, recommended density of 1,000‒2,000 single or double cladodes per ha, with a spacing of 5‒7 m between rows and 1‒2 m within rows.  For alley cropping, wide rows (e.g. 10‒15 m) with the crop in the interspace.  Initial weed control necessary.

Fertilizer

In spite of thriving particularly well on good soils, fertilization is applied only in intensively managed plantations, e.g. including fertigation.  Exported nutrients (kg/ha/yr), based on 20 t harvested DM/ha/yr, are about 180 kg N, 32 kg P, 516 kg K and 470 kg Ca and must be replaced by fertilization if the system is to be sustainable.  Organic fertilizer is reported to be particularly effective.  Fertilization with N has been reported to increase CP content.

Compatibility (with other species)

During establishment phase, susceptible to competition by weeds.

Companion species

Legumes: Gliricidia sepium, Leucaena leucocephala and Prosopis juliflora for alley-cropping in Northeast Brazil. Suitable for alley cropping with maize, barley and sorghum.

Pests and diseases

A number of region-dependent fungal and bacterial diseases are reported for O. ficus-indica, also phytoplasmas. Their potential thread to forage plantations appears to be only little studied however. Among insects pests, cottony cochineal (Dactylopius opuntiae Homoptera: Dactylopiidae) is considered as the most important pest.  The cladodes of young plants are susceptible to attack by the cactus moth (Cactoblastis cactorum Lepidoptera: Pyralidae), the biological control agent responsible for the near-eradication of the environmental weed Opuntia in parts of Australia.

Ability to spread

Dispersal by seed through animals; also via vegetative propagation.

Weed potential

Discussion on the weed potential of O. ficus-indica is controversial.  The species is considered a landscape transformer as it displaces indigenous species and dependent animals.  In some countries (e.g. South Africa and most Australian states) it is listed as a noxious weed, but in other arid and semiarid areas, it is considered a valuable species because of its multi-use potential, provided management is appropriate.

Feeding value
Nutritive value

Nutritive value decreases with age of cladodes; concentrations of fibre und crude protein are reported to be low (CP 3‒5%, but properly fertilized >10% is possible); high concentrations of digestible carbohydrates.  IVDMD around 75%.  Very high water content (80‒95%).  It is a good source of vitamin A, calcium and magnesium, but is low in sodium, potassium and phosphorus.

Palatability/acceptability

Cladodes of spineless forms are highly palatable to livestock.  Spiny forms often require treatment such as burning or a mechanical process to remove or pulverize the spines to make the cladodes more acceptable.  Camels are able to ingest cladodes with spines intact.

Toxicity

Low amounts of tannins and saponins, also oxalates, have been reported, without affecting livestock production.

Production potential
Dry matter

About 20 to DM ha/yr are frequently reported, but >50 t DM ha/yr have been achieved in intensive cultivation systems (optimum plant density and management including fertilization; northeast Brazil).  When rehabilitated with O. ficus-indica, native rangeland productivity can increase several-fold (Tunisia).

Animal production

Supplementing low quality forage with fresh O. ficus-indica increases the average daily gain of growing ruminants, particularly when N is added.  In diets of dairy cows and dairy goats, a considerable portion of concentrates can very economically be substituted by O. ficus-indica.

Genetics/breeding

2n = 22; cultivated forms may be octoploids (2n = 88) or hexaploids (2n = 66).  Triploids (2n = 33), tetraploids (2n = 44) and pentaploids (2n = 55) have also been identified.  There are breeding programs (including hybridization with other Opuntia species), part of which also focus on forage production, in Mexico, Brazil, Italy and USA.  Main selection criteria for forage types are improved nutritional content, frost tolerance, spineless cladodes, high productivity and quick recovery after pruning, wider adaptability (especially to tropical dry & heat), adaptation to intensive production systems, and  pest and disease tolerance.

Seed production

Though establishment of O. ficus-indica is mainly by vegetative propagation, seed production is possible; after initial dormancy (scarification necessary), maximum germination occurs after 9 months.

Herbicide effects

Pre-emergence herbicides, Diuron, Tebuthiuron, or a combination of Simazine and Ametryne, are effective for weed control at establishment. To combat O. ficus-indica when it becomes invasive, a combination of chemical, mechanical (incl. fire) and biological controls has been suggested.
