Beans: Cultivation and Varieties
Beans are among the most essential plants cultivated by humans, providing both nutritional and agricultural benefits. Rich in iron and plant-based protein, they are especially helpful for individuals with anemia. Additionally, beans enrich the soil with nitrogen-fixing bacteria found in their roots. Beans are commonly grown in home gardens for their nutritional value and aesthetic appeal.
