Question

plz.. answer the above question

Answer 1

We have ministers of of agriculture and commerce at the national level to look after the overall practices of the trade and commerce going on in different states and suggests measures for improvement.

Answer 2

Although agriculture and commerce are the state subjects we have ministers of agriculture and commerce at the union because of the wider prospect of these subjects regarding inter-state trade. So a uniform policy has to be legislated.
Secondly, the agricultural and economic experts are part of the Planning Commission. So we require agricultural and commerce ministers in the Union for “policy making”.
