A 2‐year field experiment conducted in Erzurum, Türkiye, assessed the impact of planting geometry (PG) on sweet corn yield and quality using three genotypes (G)−Argos F 1 , Challenger F 1 , and Khan F 1 −and eight different PG. The study revealed that both PG and G significantly influenced quality traits such as ascorbic acid (AA), total soluble solids (TSSC), total sugar content (TSC), glucose (Gl), sucrose (Suc), and kernel protein content (KPC). The optimal PG arrangement was identified: 50 × 18 cm for KPC and Gl, 70 × 15 cm for AA and Suc, and 40 × 21 cm for TSSC. Among the genotypes, Khan F 1 exhibited superior traits in ear length, ear weight, and AA, while Challenger F 1 excelled in KPC, TSSC, and Suc. The highest quality outcomes were observed when Argos F 1 was cultivated at a plant geometry of 50 × 18 cm for KPC and Challenger F 1 at the same spacing for both TSSC and Suc. Overall, the plant geometries of 40 × 21 and 50 × 18 cm, in combination with the Challenger F 1 hybrid, demonstrated superior sweet corn quality parameters. Therefore, cultivation of the Challenger F 1 hybrid at a spacing of 50 × 18 cm is recommended for optimizing sweet corn quality attributes.
