The domestication of plants is the process of adapting wild plants to domestic conditions. Plants were first domesticated about 10 000 years ago. Early farmers gathered the seeds from the wild plants, planted them in soil that was rich in nutrients, gave the plant enough space to grow without competition from other plants, and gave these plants lots of water. When the plants were ready, the farmers then harvested the food crops. The earliest known plants that were domesticated are wheat, barley, lentils and peas.
