Question

plateau regions in India do not support agriculture as much as the plain regions what are the reasons for this

Answer 1

Hi Shobha
Your answer :
Plateau regions usually have a thin soil cover and are rocky plus they do not receive adequate rainfall but Plains receive adequate rainfall and have a fertile soil favouring agriculture.
Hope I could help

Answer 2

The foremost and primary reason is the soil and relief. The plateau region is the oldest tectonic block of the Indian subcontinent. It has a highly eroded surface and mainly consists of hard rocks. Due to this reason, there is a very thin layer of soil in this region that too is not fertile and lack humus content.

The next important reason is the lack of availability of water throughout the year. The rivers of this region are rain-fed thus in summers they hardly have water to support agriculture in the region.
