How long have pulses of different geographic origins been grown?

Pulses, which are a category of legumes that include beans, lentils, and peas, have been cultivated for thousands of years across various regions of the world. The option stating a time frame of 2,000 years aligns with archaeological and historical evidence indicating that pulses have been an essential part of human agriculture since ancient civilizations began practicing farming. For instance, the domestication of pulses traces back to significant ancient agricultural centers, where they played a vital role in providing dietary protein, soil fertility through nitrogen fixation, and crop rotation practices.

In particular, regions such as the Middle East, South Asia, and parts of the Americas have records dating back over two millennia for the cultivation of different pulse varieties. This long-standing agricultural tradition is crucial, as the historical significance of pulses not only highlights their role in food security and dietary needs but also emphasizes their environmental benefits in sustainable agricultural systems.
