If a monoculture of corn provides 5600 lbs/acre and a monoculture of peas provides 1200 lbs/acre, and when the two products are intercropped, the corn provides 4600 lbs/acre and the peas 800 lbs/acre, what is the land equivalency ratio of the corn and peas separately? together?
Note: land equivalency ratios can be based on any crop output per unit area.
LER of the indicates that 49 percent yield advantage is obtained when grown as intercrops compared to growing as sole crops. In other words, the solo crop has to be grown 1.49 acres to get the same yield level that is obtained by intercropping.
