Arachis hypogaea Peanut Kacang tanah Leguminosaceae
 

Arachis hypogaea, Peanut, Kacang tanah

 
Arachis hypogaea, Peanut, Kacang tanah

The species name comes from the Greek for ‘below the earth, referring to the unique botanical feature of this plant.
It is an annual that requires a long, warm growing season for the fruit to mature fully. It grows to about 12 in (30 cm) tall and has leaves with 4 leaflets and the red-veined, yellow flowers.
Cultivation: Anyone can grow peanuts simply by purchasing raw peanuts from a health-food store and planting them just like beans, to which their cultivation requirements are very similar. The soil needs to be loose and open to allow the pegs to penetrate.
They require a protected, sunny position .

The peanut plant hides its fruit in the ground.
Arachis is a genus endemic (restricted) to South America, and the homeland appears to have been the Andean foothills in Bolivia.
Today peanuts are cultivated throughout the tropical and subtropical world and even grow at 45 degrees N in Asia and Canada, where the summers are hot. The leading producers of this crop are China, India, the United States, Nigeria, and Senegal, and peanut production (over 20 million metric tons annually) ranks in the top 25th among world food .
Typical time for the process from planted seed to dried pods is about five months.
Seeds are important sources of vegetable oil and protein. The triglycerides (oil) are high in oleic acid and moderately high in linoleic acid but low in others; it is a nondrying oil, i.e., it remains liquid and does not form a surface film when exposed to air. Seeds contain 36-50% oil and usually 25-30% (to 40%) protein. Oil can be expressed simply by crushing or with hot or cold treatments. This product is widely used as a cooking oil and as a lubricant. The oil is also used to manufacture items ranging from shaving cream and soap to plastics. Seedcake had been used for livestock feed and fertilizer, and shells have been used as filler for wallboard and insulation.
Of course, seeds can be consumed after being salted or roasted. In the United States more than 50% of all peanuts are used to make peanut butter. These seeds are an excellent protein source and are valuable for the malnourished peoples in Africa and Asia.
The U.S. harvest is almost two metric tons of fruits per acre.
