Özet

A 2-year field experiment conducted in Erzurum, T & uuml;rkiye, assessed the impact of planting geometry (PG) on sweet corn yield and quality using three genotypes (G)-Argos F1, Challenger F1, and Khan F1-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 & times; 18 cm for KPC and Gl, 70 & times; 15 cm for AA and Suc, and 40 & times; 21 cm for TSSC. Among the genotypes, Khan F1 exhibited superior traits in ear length, ear weight, and AA, while Challenger F1 excelled in KPC, TSSC, and Suc. The highest quality outcomes were observed when Argos F1 was cultivated at a plant geometry of 50 & times; 18 cm for KPC and Challenger F1 at the same spacing for both TSSC and Suc. Overall, the plant geometries of 40 & times; 21 and 50 & times; 18 cm, in combination with the Challenger F1 hybrid, demonstrated superior sweet corn quality parameters. Therefore, cultivation of the Challenger F1 hybrid at a spacing of 50 & times; 18 cm is recommended for optimizing sweet corn quality attributes.
