Detailed explanation-1: -The most widespread irrigation system in India was undertaken in India in the medieval period by the Sultanate rulers. Firoz Shah Tughlaq (1309-1388) built the most extensive canal irrigation system around the Indo-Gangetic doab and the region west of the river Yamuna in the fourteenth century.
Detailed explanation-2: -Irrigation is important to a country like India because rainfall here is seasonal in nature. It is limited to four months of a year. It is also important because some crops require more water than what it is provided by the rainfall, therefore we have to depend on irrigation.
Detailed explanation-3: -Irrigated agriculture is, on average, at least twice as productive per unit of land as rainfed agriculture, thereby allowing for more production intensification and crop diversification.
