Abstract In order to observe the effects of sowing date on the ‘Mibaek 2’ waxy corn cultivar, we investigated the morphological traits of individuals under early, mid, and late sowing conditions. The budding of early (April 19th), mid (May 10th), and late (May 24th) sown plants was observed at 12 d, 7 d, and 6 d after sowing, respectively. The silking of early, mid, and late sown plants was observed on June 29th, July 14th, and July 27th, respectively. Most of the early-sown plants had an average height of 200 cm, with a minimum of 185 cm and a maximum of 210 cm, while mid-sown plants had a mean height of 212 cm with a minimum of 196 cm and a maximum of 233 cm. The average height of late-sown plants was 232 cm, with a minimum of 215 cm and a maximum of 241 cm. The longest ear length and the highest value of 100-kernel weight were observed in early-sown plants compared to mid-and late-sown plants. Our findings suggest that it is more advantageous to sow the ‘Mibaek 2’ waxy corn cultivar as early as possible to obtain the highest productivity.
