| Land Equivalent Ratio (LER) |
In agriculture,
land equivalent ratio (LER) refers to relative landmass required under sole cropping to produce same yield as in the case of intercropping. In simple mathematical terms, LER is the sum of the fractions of intercropped yields divided by the single crop yield. It is also known by the name of
relative total yield.
For m number of crops
Here,
IY is the yield of the crop under intercropping and
SY is the yield of the crop under sole cropping
The stand value of LER is 1.4
