Which Sultan established a separate department (Diwan-i-Amir Kohi) to take care of agriculture?

Muhammad Bin Tughlaq

The correct answer is Option 3- Muhammad Bin Tughlaq

Muhammad Bin Tughlaq established a separate department (Diwan-i-Amir Kohi) to take care of agriculture.

The Diwan-i-Amir Kohi was responsible for increasing agricultural production and improving the lives of farmers. It provided loans to farmers for the purchase of seeds, cattle, and equipment. It also helped farmers to build irrigation systems and improve their farming techniques.

The Diwan-i-Amir Kohi was a progressive initiative, but it was not ultimately successful. This was due to a number of factors, including corruption among government officials and the difficulty of managing such a large and complex department.

Jalal-ud-din Khalji, Khizr Khan, and Tughril Beg were all rulers of Delhi, but they did not establish the Diwan-i-Amir Kohi.
