ارہر, commonly known as Pigeon Pea, is a leguminous plant widely cultivated in tropical and subtropical regions. It is valued for its nutritious seeds, which are a rich source of protein, fiber, and essential vitamins. The plant typically grows to a height of 1 to 2 meters and produces yellow flowers that develop into pods containing the seeds. In addition to its nutritional benefits, ارہر plays a significant role in sustainable agriculture. It helps improve soil fertility through nitrogen fixation, making it an excellent crop for rotation with other plants. Its resilience to drought conditions also makes it a vital food source in areas prone to water scarcity.
