You’ve done a large series of experiments, growing different combinations of crop plants together. Which of the following experimental plots would identify species that would be good candidates for companion planting (being planted together) in a commercial situation? The goal is to maximize the yield of each species planted, and increase overall yield compared with single-species plantings.

genotypic mixtures have more critical yield quality than monocultures, particularly when under regular tension; the yield of individual genotypes is more factor inside mixture than monocultures anyway pay by more grounded contenders inside the mixture creates a development in yield sufficiency for the mixture with everything taken into account; and genuine limit can be seen from plant phenotype
Plants were created as the two monocultures and four-course blend between genotypes was expanded by boosting the partition between plants of a comparable genotype. Seeds were planted in Levington F2 soil and were agonized at 4°C for 4 d to break torpidity before being moved to the glasshouse at 21–23°C on a 16 h light/8 h diminish cycle upgraded with 120 μmol fluorescent lighting for germination
Hence, the right answer is "combination of grams/individuals higher than the monoculture"
