Reaping – cutting the mature panicles and straw above ground. Threshing – separating the paddy grain from the rest of cut crop. Cleaning – removing immature, unfilled, non-grain materials. Hauling – moving the cut crop to the threshing location.

What are the methods of water harvesting in India?

Surface runoff harvesting is the most suitable method in urban clusters. Here, streams of surface runoff rainwater are redirected and stored for future use in specially-built reservoirs, either on the surface or underground. This provides a steady supply of clean, potable water, and also water for normal domestic uses.
