• Individual

Investigation was done on individual potted potato plants. The data presents results from a complete randomized block design greenhouse factorial pot experiment with eight treatments and ten replicates per treatment (n = 80) with one potato plant (S. tuberosum, ‘Fontane’). In each potted potato we measured Aphid population growth, AMF root colonization, potato biomass, potato tuber yield, N & P in leaves, and potato plant metabolites (using LC-MS untargeted methods).

• Experimental study

We used a green-house experiment with potato plants to explore the soil legacy effects of mono-cropping versus strip-cropping systems, AMF inoculation and aphid infestation on AMF root colonization, the induction of plant defences (untargeted LCMS-based metabolomics), aphid population size and potato yield.

Individual potato were left to grow for 10 weeks and then each potato was , sampled for yield (tuber weight and numbers), biomass (dry weight), aphid count, AMF root colonization % (using the staining method). Metabolites in the leaves were assessed using LC-MS analyses and then annotated manually and using available datasets in KNAPSACK.

Experiment

We conducted a complete randomized block design greenhouse factorial pot experiment with eight treatments and ten replicates per treatment (n = 80) with one potato plant (S. tuberosum, ‘Fontane’) per 5 L pot, at Wageningen University, Netherlands, between February and April 2022. The experiment consisted of three factors, ‘Strip-cropping legacy’ (with two levels), ‘AMF inoculation’ (with two levels) and ‘Herbivore’ (with two levels). The greenhouse was organized in ten spatial blocks and each of the eight treatments was present in each block.

• Netherlands

For the strip-cropping legacy treatments, plants were grown either in soil from the middle of 100 m2 mono-cropped plots (mono) or from the edge of strip-cropped plots (strip), collected from the long-term organic strip-cropping experiment at Wageningen University (51°59’33.06” N, 5°39’43.56” E)
