Peanut

Peanut (Arachis hypogaea L.) is a significant annual legume crop belonging to the Fabaceae family. Known globally as the groundnut, this plant is unique due to its geocarpic fruit development. After pollination, the flower stalk (peg) elongates and drives the ovary into the soil, where the pods develop and mature, necessitating specific soil management practices to ensure a successful harvest.

Originating from South America, the peanut has become a vital crop in tropical and subtropical regions worldwide. It thrives in climates with a long growing season and high temperatures, typically requiring consistent sunshine. While it is highly adaptable, the crop remains sensitive to frost and extreme cold, which can significantly damage plant tissues and prevent pod formation.

Successful peanut agronomy relies on choosing well-drained, loose, sandy loam soils that facilitate peg penetration. Field preparation involves fine tillage to remove clods. Irrigation management is critical, particularly during the flowering and pod-filling stages, to maintain soil moisture levels that support healthy development. Weed control is essential to minimize resource competition during the early growth period.

Peanuts serve a wide range of industrial and nutritional purposes. They are a primary source of high-quality vegetable oil and protein-rich snacks. The oil is widely used in cooking and food manufacturing, while peanut butter is a staple in many diets globally. Furthermore, the residual crop material (hay) and meal serve as valuable high-protein feed for livestock and poultry production.

Farmers must monitor crops closely for common pathogens that can compromise yield quality and quantity. Integrated pest and disease management is essential to prevent significant losses caused by various agents:

• Alternaria blight and Anthracnose
• Verticillium wilt
• Helminthosporium leaf spot and Rhizoctonia rot
• Sclerotinia blight and Ashy stem blight
• Tomato spotted wilt virus
