Planting geometry is one of the most important management practices that determine plant growth and yield of corn. The effects of eight planting geometries (35 x 23 cm, 40 x 21 cm, 45 x 19 cm, 50 x 18 cm, 55 x 17 cm, 60 x 16 cm, 65 x 15 cm, 70 x 15 cm) on plant growth and yields of three sweet corn hybrids (Argos F-1, Challenger F-1, Khan F-1) were investigated under Erzurum, T & uuml;rkiye conditions in 2022 and 2023 years. Variance analysis of the main factors shows a highly significant effect on whole traits but in two-way interactions some of the traits were significant and in the three-way interactions, it was insignificant. As an average of years, the number of plants per hectare at the harvest varied between 92,307 (35 x 23 cm) and 120,444 (70 x 15 cm) according to the planting geometries. The highest marketable ear number per hectare (107,456), marketable ear yield (24,887 kg ha(-1)), and fresh kernel yield (19,493 kg ha(-1)) were obtained from the 40 x 21 cm planting geometry. The results showed that the variety Khan F-1 grown at 40 x 21 cm planting geometry obtained the highest marketable ear number (112,472), marketable ear yield (29,788 kg ha(-1)), and fresh kernel yield (22,432 kg ha(-1)). The plant density was positively correlated with marketable ear number (r = 0.904 **), marketable ear yield (r = 0.853 **), and fresh kernel yield (r = 0.801 **). The differences among the varieties were significant for the studied traits, except for plant density and kernel number per ear. In conclusion, the variety Khan F-1 should be grown at the 40 x 21 cm planting geometry to maximize yields under study area conditions without water and nutrient limitations.
