All three plants listed – Groundnut (*Arachis hypogaea*), Horse-gram (*Macrotyloma uniflorum*), and Soybean (*Glycine max*) – belong to the pea family, also known as Fabaceae or Leguminosae. Plants in this family are commonly referred to as legumes and are known for their characteristic pods and ability to fix atmospheric nitrogen through symbiotic relationships with bacteria in root nodules.
The Fabaceae family is one of the largest plant families and includes many economically important crops such as beans, peas, lentils, chickpeas, soybeans, peanuts, and clover.
Legumes are a valuable source of protein and fiber in human diets and play a significant role in agriculture due to nitrogen fixation, which improves soil fertility.
