How We Calculate This
Total plants = Rows x Plants per row. Block dimensions are calculated from spacing in all directions.
Seed count includes 50% extra to account for germination failures and thinning (sow 2 per station, thin to the strongest).
Yield estimate assumes 1.5 cobs per plant on average, which is typical for UK-grown sweetcorn.
