There was an error in equation 6 and the following sentence, and in Table 4.
Eqn 6 should be
Li(ijk) = Yi(ijk)/(Yi(ij) * 2)
The factor of 2 in the denominator in equation 6 ensures comparability to the values calculated in equation 5.
Table 4. Partial LER values of the component crop (P: pea; B: barley; R: rape) dry matter yields at final harvest for the triple intercrop (PBR).
Calculations were based on equations 5 and 6, using sole crop (SC) and dual intercrop (IC) yields as reference, respectively. Values are means
