public spending on irrigation. The efficiency is measured through technical efficiency scores based on the Data Envelope Analysis approach. The analysis is
carried out at 2011–12 prices across 20 major Indian states from 1981–81 to 2015–
16 and in different time periods to appraise the improvements therein.
We find a considerable increase in public expenditure on agriculture and minor,
medium, and major irrigation during 2000s compared to the preceding decades. The
per hectare public irrigation capital stock significantly increased from Rs. 1688 in
TE 1983–84 to Rs. 18239 in TE 2015–16. High per capita income states spent more
