A S Kahlon and Grewal's paper demonstrates this relationship for Punjab (vide Introduction, p XI), with multivariate analysis, but unfortunately it is not included for publication in the book.

The reviewers own research (unpublished) on time series data for UP has revealed that crop intensity bears an elasticity of almost unity with irrigated area.
