Hume made a number of suggestions for the improvement of agriculture placing carefully gathered evidence for his ideas. He noted the poor yields of wheat, comparing them with estimates from the records of Emperor Akbar and yields of farms in Norfolk. Lord Mayo supported his ideas but was unable to establish a dedicated agricultural bureau as the scheme did not find support from the Secretary of State for India, but they negotiated the setting up of a "Department of Revenue, Agriculture and Commerce" despite Hume's insistence that "Agriculture" be the first and foremost aim. The Department had charge on land revenue, settlements, advances for works in agricultural improvement, horticulture, livestock breeding, silk, fibre, forests, commerce and trade, salt, opium, excise, stamps, and industrial art. It also collected data and was in charge of censuses, the gazetteers, surveys, geology, and meteorology. Hume was made Secretary of this department in July 1871 leading to his move to Shimla.
