Characteristics of Peanut
Peanuts are herbaceous annual plants that can reach up to 50 cm in height. They have compound leaves, usually with four leaflets. The plants produce yellow, orange, or cream-colored flowers. After pollination, a unique geocarpy process occurs where the flower stalk elongates and forces the developing fruit into the soil.
The peanut seeds, enclosed in a pod, develop underground. Each pod contains 1 to 4 seeds. Peanuts are rich in proteins, fats, and various vitamins and minerals, making them a valuable food source.
Geographical Distribution and Habitat of Peanut
Peanuts are native to South America, specifically the region encompassing parts of Bolivia and Argentina. They thrive in tropical and subtropical regions and are cultivated in over 100 countries worldwide. Major producers include China, India, Nigeria, the United States, and Sudan.
Peanuts require well-drained sandy loam or sandy clay loam soils with a pH between 5.9 and 7. Their growing season typically ranges from 120 to 150 days, with the crop favoring temperatures between 20°C and 30°C.
