The peanut plant probably originated in Peru or Brazil in South America. The Spanish explorers and traders spread them to Asia, Africa and finally to North America. Initially, peanut is mainly used for oil, food and as a cocoa substitute. Recent technological enhancement aids, demand for peanuts grew rapidly, especially for oil, roasted and salted nuts, peanut butter and candy. Peanut is a great source of protein.

Peanut is native from the western Hemisphere and probably originated from peru or brazil in South America. Spenish have explores the versatility of peanut’s and later, traders bring to Asia and Africa. Africans have introduces the peanut to North America. Currently, China, India and USA grows the major amount of peanuts

Peanut is essentially a tropical plant. It requires a long and warm growing season. The most favorable climate conditions are a well distributed rainfall at least 50 cm during growing season, abundance of sunshine and relatively warm temperatures. The temperature for the best growth of plant is from 21-26.5°C. During ripening period it requires about a month of warm and dry weather. Peanut thrives best in well-drained sandy and sandy loam soils, as light soil helps in easy penetration of pegs and their development and also harvesting. Clay or heavy soils are not suitable for this crop, as they interfere in penetration of pegs and make harvesting quite difficult. Groundnut gives good yields in the soil with pH between 6.0-6.5.

Sowing of groundnut will be taken place with the advent of monsoon in the last week of June or in the first week of July. Delay in Sowing causes progressive reduction in the yield. Where irrigation facilities are available, sow groundnut around 20th June or 10-12 days before the onset of monsoon with a pre-sowing irrigation. This helps in best utilization of monsoon by the crop because all the germination will take place before rains start which ultimately result in a higher yield. It will also help in getting the field vacated in time for the sowing of Rabi crops. In southern part of the country where groundnut is sown in Rabi season also, it should be sown in the month of November and December.

It is necessary to dig the pods at the right time for obtaining higher yields of pods and oil. Harvesting should be done when good percentage of nuts is fully developed and fairly intact. The crop takes approximate 90- 110 days to attain full development. Leave the harvested crop in small heaps for two three days for curing. After curing, collect the crop at one place and detach the pods either by hand or using groundnut plucker for separating the pods from the plants.

Major producing states in India are Gujarat, Andhra Pradesh, Tamil Nadu, Rajasthan, Karnataka and Maharashtra

Currently, peanut is commercially available in various forms such as roasted and salted nuts, peanut butter and candy. Peanut is also utilized as edible oil.

Mainly, two variant of groundnuts are cultivated in India namely, Virginia (Bold) and Spanish (Java). Mostly, winter crop of peanuts is rain-fed crop and more than 70% crop is of bold variety. Whereas, the summer crop is irrigated and 85% crop is of Java variety. The Bold peanut are typically red skinned with elongated shape whereas, the Java variety peanuts are pink skinned with round spheroid shape. Bold variety of peanut contains a large percentage of oil content approximately 25%. JAVA peanuts contains high amount of protein and high concentrations of antioxidants polyphenol.

Bold Peanut:

Bold peanut is generally cultivated as a winter crop due to huge irrigation requirement. Seeds are typically red skinned with elongated shape. Bold contain the great amount of oil content (more than 25%). Approximately 70% winter crop of peanut are of bold variety. This variety is also famous as Virginia peanut

Java Peanut:

Java Peanut is also known as Spanish peanut, which is generally harvested as an irrigated crop. More than 85% crops harvested in summer are of Java variety. Java peanut are pink skinned with round spheroid shape and contains high amount of protein and high concentrations of antioxidants polyphenol.
