Handpicking, Threshing, Winnowing
Handpicking: manually remove unwanted items (remove stones from dal). Threshing: separate grain from stalks by beating on hard surface (paddy, wheat). Winnowing: use wind to separate light chaff from heavier grain (hold high, pour โ wind blows chaff away). These are ancient Indian farming techniques.
