Which of the following Delhi Sultans is credited with establishing the separate agrarian department known as 'Diwan-i-Kohi' to promote agriculture and bring wasteland under direct state cultivation?

💡 Solution & Explanation

Muhammad bin Tughluq established the Diwan-i-Kohi department to extend cultivation through state-sponsored loans and agricultural planning, although the project largely failed due to poor soil selection and administrative corruption. Firoz Shah Tughluq created the Diwan-i-Bundagan for slaves and Diwan-i-Khairat for charity, while Alauddin Khalji instituted strict market controls and direct revenue assessment. The agricultural experiments of the Tughluq era reflect attempts to maximize imperial agrarian output.
