The Bambara groundnut (or Bambarra groundnut) is a member of the family Fabaceae. According to some authors it is Voandzeia subterranea, but others place it in Vigna. The plant originated in West Africa. Still a traditional food plant in Africa, this little-known vegetable has potential to improve nutrition, boost food security, foster rural development and support sustainable landcare.[1] The bambara groundnut ripens its pods underground, much like the peanut (also called a groundnut). They can be eaten fresh or boiled after drying.

The original local name for Bambara nut is cokon (Bamanankan). Bambara groundnuts are also known as jugo beans or in Swahili, njugumawe. In the Republic of Zambia, bambara groundnuts are known as either ntoyo (ciBemba),katoyo (kiKaonde), or mbwiila (chiTonga). In Shangaan they are known as tindluwa. In Malagasy they are known as voanjobory. In Hausa language it is variously referred to as "Gurjiya" or "Kwaruru". In Goemai language of Plateau State of Northern Nigeria it is known as "Kwam", and Kanuri people refer to it as "Ngamgala". In Indonesia it is called "kacang bogor", which literally means "Bogor peanut", because this plant is widely cultured in Bogor, West Java. In the Shona language of Zimbabwe it is known as "Nyimo", and "indlubu" in the ndebele language. In the Ibo language in eastern Nigeria, it is commonly known as "Okpa". In the Northern part of Yoruba, it is commonly known as "Epa-kuta", and in the Gha Language, spoken by the people in Greater Accra, Ghana, the Bambara Bean is called "Akwei".

Origin and regions of cultivation

The origin of the Bambara groundnut is West Africa[2] and the region of cultivation is Sub-Saharan Africa's warm tropics.[3]

Importance in the World Food System

Bambara groundnut represents the third[4] most important grain legume in semi-arid Africa. “It is resistant to high temperature and is suitable for marginal soils where other leguminous crops cannot be grown”.[5] In addition, it makes very little demand on the soil[6] and has a high nutritive value with 65% carbohydrate[7] and 18% protein[7] content. For these reasons it is not prone to the risk of total harvest failure even in low and uncertain rainfall regions. "Due to its high protein value it is a very important crop for poorer people in Africa who cannot afford expensive animal protein."[6]

Product use

The seeds are used for food and beverage due to its high protein content[8] and for digestive system applications.[8] The entire plant is known for soil improvement[8] due to nitrogen fixation.

Soil requirements

Optimal soils for Bambara groundnut production are sandy soils to prevent water lodging. optimal soil depth is between 50 and 100 cm,[8] with a light soil texture.[8] soil fertility should be low[8] and soil pH is best suited between 5 and 6.5[8] and should not by lower than 4.3[8] or higher than 7.[8]

Climate requirements

The production is best suited between a latitude of 20° - 30°,[8] i.e. the tropical wet and dry (Aw)[8] and the subtropical dry summer (Cs)[8] climate zones. Optimal temperature is between 19°C[8] and 30°C.[8] Temperatures below 16°C[8] and above 38°C[8] are not suited for the production of bambara groundnut. The bambara groundnut is very drought resistant.[3] The minimal annual rainfall requirement is about 300 mm[8] and optimal annual rainfall is between 750 mm[8] and 1400 mm[8] and should not exceed 3000 mm.[8]

Cropping system

The cropping system is semi-permanent[8] and the Bambara groundnut can be cultivated as single crop or as intercrop.[8] Best suited intercrops are sorghum,[8] millet,[8] maize,[8] groundnut,[8] yams[8] and cassava.[8]

Bambara groundnut is mainly cultivated as intercrop, however the planting density varies between 6 to 29 plants per square meter[9]. For woodland savannas of Côte d'Ivoire the highest yield is attainable with a plant density of 25[10] plants per square meter.

Fertilization

Since Bamabara groundnut is usually intercropped, no fertilizer is applied. A yield of 1000 kg seed and 925 kg leaves remove 55.7 kg N,[11] 26.2 kg K,[11] 25.1 kg C,[11] 7.8 kg P[11] and 6.6 kg Mg.[11] Since Bambara groundnut is a legume, phosphor is the most important nutrient. An application rate of 60 kg/ha[12] of P2O5 is recommended for bambara groundnut in Yola, Adamawa State Nigeria.

Production

World production of Bambara groundnut increased from 29'600 tonnes[13] in 1961 to 79'160 tonnes[13] in 2008, while the yield during this period did not increase. "As an under-utilised crop,bambara groundnut has not received sustained research"[14] until the recent years and therefor no yield increase occurred.

Pest & Diseases

Pest and diseases are not considered to be a serious problem for Bambara groundnut.[11]

Reported diseases[11]:

  • Leaf spot (Cerscospora canescens & Phyllosticta voandzeia)
  • Powdery mildew (Erysiphe sp.)
  • Wilt (Fusarium sp.)
  • Leaf blotch (Phomopsis sp.)
  • Stem rot (Scleorotium rolfsii)

Reported pests[11]:

  • Aphids (Aphis sp.)
  • Bruchids (Callosobruchus sp.)
  • Leaf hoppers (Hilda patruelis)
  • Termites
  • Root-knot nematodes (Meloidogyne javanica)

Physiology

Growth

The growth cycle is between (min-max) 90–180 days[8] and under optimal conditions the cycle is about 120–150 days[3] to pod maturity. Flowers appear 40–60 days[3] after planting. 30 days[3] after pollination the pod reaches maturity and during another 10 days[3] the seeds fully develop.

Generative reproduction

Generative reproduction is for the Bambara groundnut autogamous[3] (self-fertilization) and cleistogamous[3] (self-pollinating).
