Solution(By Examveda Team)

Productivity of an intercrop per unit area of ground compared with that expected from sole crop sown in the same proportions is termed as Land Equivalent Ratio.
The Land Equivalent Ratio (LER) is the ratio of the area under sole cropping to the area under intercropped needed to give equal amounts of yield at the same management level. It is the sum of the fractions of the intercropped yields divided by the sole crop yields.
