The consumption of Irvingia gabonensis seeds is proscribed by provide, and in city areas, by excessive costs (Division of Forest Useful resource Administration, Nigeria 1986).
Agbor (1986) carried out an intensive research of Irvingia gabonensis advertising and marketing and manufacturing. There are two varieties of Irvingia sp., one produces a candy fruit and is mostly consumed uncooked, the different is a bitter selection exploited for its seed. Agbor discovered that there was a higher demand for the bitter selection.
The costs for seeds and fruit have been decrease in the wet season, and in all instances significantly dearer in non-producing districts. He discovered that there was nice variation in the density of timber in several southern districts starting from a mean 87 timber per farmer in Ogoja district to a mean two timber per farmer in Ikono district.
Tree density corresponded to variations in land availability: greater tree densities mirrored much less land stress. Irvingia gabonensis offered an essential supply of earnings for a lot of farmers (see additionally Part 5.3).
In southwestern Cameroon, Irvingia gabonensis fruit and seed are additionally generally marketed. In the Korup area they’re usually gathered, dried and bought to Nigerian merchants or taken to Nigerian markets (the place one bucket fetches roughly FCFA 10,000) (Gartlan 1987, Division of Forest Useful resource Administration 1986).

Irvingia gabonensis is one of the most essential indigenous fruit timber cultivated and commercialized in Edo Central, Nigeria. On this research, the yields of fruits and seeds of Irvingia gabonensis have been evaluated in conventional agro forestry and compound farming techniques.
The outcomes confirmed that the imply fruit yield of the species are 620 and 850 fruits/tree whereas the projected imply fruit productions/hectare are 76,880 and 105,400 fruits in the two techniques respectively. Imply seed yield of 18.24kg and 25kg of dry cotyledon per tree was recorded with a projected cotyledon yields/hectare of 2,262 kg/ha and 3,100 kg/ha respectively.
In the open market, 50g of dry cotyledons of the species sells for N 170.00, whereas common farmers earnings from fruits manufacturing of the species per family is about N 3,675.00 yearly.
Irvingia gabonensis and I. wombulu; the bush mango are the sources of ‘Ogbono’ , the Irvingia kernel which is popularly used as soup thickener in most West African nations.

Not too long ago, an try at setting native high quality requirements for the kernels in commerce has commenced. Standardization of this can assist export promotion and the enhance of monetary returns to the rural farmers who accumulate from the forests and manually course of (nut extraction) and solar dry for storage earlier than advertising and marketing.
The varied initiatives of ICRAF, NACGRAB and CENRAD on the assortment of the remaining genetic assets of Irvingia in West Africa, its institution in genebanks and the potentials to make the most of chosen strains in new planting offers hope for the future. It’s believed that this can present the seed for the sustainable manufacturing of Irvingia as deforestation and outdated tree age is already affecting wild assets.
Pure stand plantations and timber in agroforestry techniques are engaging. Multistrata agroforestry system for manufacturing is presently being established in Nigeria inside the southern forest zones the place bush mango is well-known.
