Introduction
- Groundnut (Arachis hypogaea Linn.) is one of the principal economic crops of the world ranking 13th among the food crops and it has been accepted by Indians as a vegetable oilcrop during the middle - to - late nineteenth century.
- It is generally distributed in the tropical, sub-tropical and warm temperate zones of the world covering in over 80 countries.
- The limits of commercial production are between latitudes 40°N and 40°S. This crop is also known as peanut, monkeynut, goobernut and earthnut.
- The Spaniards introduced the name "mani" for groundnut found growing in Peru. An European missionary, Bartolome Las Casas, who sailed in 1502 in Hispaniola (now, Haiti Dominican Republic, West Indies) and traveled throughout the Spanish lands from 1510 to 1547, was the first to encounter the groundnut called, "mani", This name is still used in Cuba and Spanish South America.
- A Calvinist missionary with the Huguenot colony founded in 1555 on the island in Rio de Janeiro bay, also encountered groundnut in this region called, "manabi".
- These confirm South America as the place of original cultivation of groundnut and its wide distribution throughout the tropical and sub-tropical areas before and at the time of discovery of America. Later, groundnut became known to European naturalists early in 17th century.
- The Portuguese naturalist, Gabriel Soares de Souza, who lived in Brazil between 1570 and 1587 gave the first detailed description of the plant, its cultivation and artificial curing
- The French naturalist, Charles Plumier (1693) is credited with coining the French name, "Arachide" for the plant called "manobi" in parts of South America and in the French Antilles. Finally, Jean Baptiste Labat (1742), who lived in the French Antilles from 1693 to 1705, gave a remarkable description of groundnut and also listed its alimentary uses.

Origin and Spread
- The South American origin of cultivated groundnut was disseminated to Europe, to both coasts of Africa, to Asia (China, Indonesia, India) and to the Pacific islands and finally to the south eastern United States. The Spanish type groundnut (seed) was introduced from South America (Brazil) into Portugal in 1784 and part of it sent to Rome (Italy). Then it spread to Valencia (Spain) and to South France. The Spanish type was first cultivated in Europe by Spaniards for oil and thus, derived the term, `Spanish'.
- The first introduction of groundnut, runner growth habit (var. hypogaea) into the United States was probably from Africa. The small poded, short seasoned Spanish (var. vulgaris) was, however, introduced from Spain in 1871.
- The Valencia type (var.fastigiata) spread throughout the world from Paraguay and central Brazil. The term `Valencia' referred that it was a recent introduction into the United States from Valencia, Spain.
Introduction into India
- The credit for the introduction of groundnut into India goes to Spaniards. It reached eastern Asia from South America and from there came to India on the east coast of Tamil Nadu and Andhra Pradesh by Spaniards.
- The Peruvian type (var. hirsuta) of groundnut from South America was first transported along the American west coast to Mexico and then across the Pacific to Phillipines, from where it spread to China and India in addition to Malaysia and Indonesia.
Adoption of groundnut as an oilseed crop
- The crop was being cultivated along with turmeric in Mysore region. The fist large scale cultivation was reported to be 4000 acres in 1850-51 in the South Arcot (now Cuddalore and Villupuram) district of Tamil Nadu state and it assumed agricultural importance gradually.
- In 1879, the area under groundnut was 1,20,000 acres, of which nearly two-third area was in Maharastra and Gujarat states and one-third in Tamil Nadu, Andhra Pradesh and Karnataka States. In 1889-90, nearly 2,79,000 acres were under this crop in Tamil Nadu, Andhra Pradesh and Karnataka states, of which over 1,85,000 acres were in South Arcot district.

Area and Production
- India, which adopted groundnut as an agricultural
crop by the late 19th century, gradually became the
major groundnut producing country in the world within
a span of 5-6 decades. India shares 22 per cent of the
world production (area 4.9 m.ha, production 5.8 m.tonnes).
- In Tamil Nadu, it is an important and major oilseed
crop, covering an area of 338300 hectares with a production
of 783200 tonnes. Out of which 70% of the area is covered
under rainfed crop and the remaining 30% is under irrigated
conditions.
- In Tamil Nadu, majority of the groundnut area (43%)
is covered in North Eastern Zone (comprises of Cuddalore,
Villupuram, Tiruvannamalai, Vellore, Kancheepuram, Tiruvallur
districts and parts of Ariyalur district).
- Hence, this agro-climatic zone is considered as a
main zone for oilseed production especially groundnut.
The crop is also popular in all the remaining zones
of Tamil Nadu except in hilly zone and high rainfall
zone.

Present
Scenario In Tamilnadu
- In Tamil Nadu, the area under groundnut is about 3.38
lakh hectares. The soils in the entire Tamil Nadu are
sandy loam. The major groundnut growing areas are Vellore,
Cuddalore, Tiruvannamalai, Villupuram, Dharmapuri, Salem,
Erode, Trichy, Madurai, Perambalur, Ariyalur, Pudukottai
and Kancheepuram districts.
- About 90% of the groundnut area is under Spanish-bunch varieties. However, Salem, Dharmapuri, Tiruvannamalai, Villupuram and Cuddloare districts have some pockets under Virginia- bunch (TMV 10, ALR 1) and Virginia-runner (TMV 1 and TMV 4) also.
- More than 50% of the Spanish-bunch area is still under the age-old varieties, TMV 2 and TMV 7. The remaining area is occupied mainly by VRI 2, JL 24, CO 2, ALR 2 and BSR 1 and red kernel local variety.
- In areas where the groundnut cultivation is practiced purely under rainfed conditions farmers prefer Virginia bunch and Virginia runner when compared to Spanish bunch.
- Of late, due to high kernel recovery, drought resistant and assured minimum pod yield the area under red kernel local Spanish bunch is on the increasing side. But the potentiality of the variety is not as high as the improved varieties.
- Even though a large number of varieties were released within a short period wide fluctuation in the spread of the varieties is observed in groundnut. This may be due to the following reasons.
- Specific varieties intended for specific season are not being adopted by the farmers as per the recommendations. This leads to low productivity.
- Due to poor seed multiplication rate (1:4 or 1:5) in groundnut, the coverage of area by a particular variety is very poor compared to cereals.
- viability of the seed is also lost within a short period.
- In general, the bunch varieties do not possess dormancy at field level.
- Wide fluctuation in market price due to import policy leads to lesser area coverage by the crop as well as the varieties.
- Economic status of the groundnut growers does not permit to reserve seeds for the subsequent seasons.
- Procurement policy of the Government and the seed certification procedure are unfavourable for the groundnut seed growers.
- Direct purchase of groundnut pods (wet) by the traders delinks the seed chain.

Importance
In Economy
- India is bestowed with the fortune of growing nine oilseed crops reflecting on the dietary importance of its population. Oilseed crops, being next to food crops hold sizeable share of the country's gross cropped area (13.0%) contributing 5 per cent of its Gross National Product (GNP) and 10.0 per cent of the value of all agricultural produce.
- India considered to be a paradise of oilseed crops having 19.0 per cent of the total world's oilseeds area and 10.0 per cent of world's oilseeds production. We are the fourth largest producers in the world in terms of output and occupying second place in area under oilseeds.
- In the past 15 years, the attainment of compound growth rate of 6.5 per cent in India's vegetable oil production front as against the world average compound growth rate of 3.5 per cent indicates the immense potential of our country's vegetable oil sector to meet the future challenges.
- The Indian Council of Medical Research (ICMR) has recommended an intake rate of 20 g of oil per day per adult (7.3 kg per year) and the requirements of edible oils at this rate by next 20 years would be almost 10.5 m.t., which could be extracted from 34.6 m.t of oilseeds. At the current level of 25.0 m.t., the country is going to face shortage of 9.0 to 10.0 m.t in the next 20 years.
- Groundnut is the major oilseed crop accounting 29.1 per cent of the total oilseeds cropped area in the country with a production share of 36.1 per cent. India also occupies a distinct position in area and production of groundnut crop in the world contributing 32.3 and 22.1 per cent respectively.
- Tamil Nadu is one among the top four groundnut producing states in the country contributing about 20.0 per cent of the groundnut production. About two third of its area is under rainfed conditions and the remaining one third is under irrigation. The area and production of groundnut are highly variable due to vagaries of monsoon. This situation obviously demands a multidisciplinary approach in our research efforts in developing economically viable and sustainable crop production and protection technologies particularly the location specific technologies.
Top
Economic Importance
- The oil content of the seed varies from 44 to 52 per cent, depending on the varieties and agronomic conditions.
- Groundnut oil is edible oil. It finds extensive use as a cooking medium as refined oil.
- It is also used in soap making, and manufacturing cosmetics and lubricants, olein stearin and their salts.
- Kernels are also eaten raw, roasted or sweetened. They are rich in protein and vitamins A, B and some members of B2 group.
- Their calorific value is 275 per 100 grams.
- The H.P.S. types of groundnut kernels are exported to foreign countries.
- The residual oilcake contains 7 to 8 per cent of N, 1.5 per cent of P2O5 and 1.2 per cent of K2O and is used as a fertilizer.
- It is an important protein supplement in cattle and poultry rations. It is also consumed as confectionary product.
- The cake can be used for manufacturing artificial fibre. The haulms (plant stalks) are fed (green, dried or silaged) to livestock.
- Groundnut shell is used as fuel for manufacturing coarse boards, cork substitutes etc.
- Being a legume with root nodules, it can synthesize atmospheric nitrogen and, therefore, improve soil fertility.
