Abstract
The sowing date of maize significantly impacts its main yield elements. The experiment, conducted at the Research and Development Station for Cattle Breeding (R.D.S.C.B.) Târgu Mureș, Sângeorgiu de Mureș, România, from 2018 to 2021, involved nine maize hybrids from different maturity groups, sown on three dates: early sowing (ES) at 6 °C soil temperature, optimal sowing (OS) at 10 °C soil temperature, and late sowing (LS) two weeks after the optimal date. The experiment was placed in a poly-factorial experience of type: A × B × C × C − R: 3 × 9 × 4 − 3, organized according to the subdivided plots method. The study examined the influence of sowing date on grain yield (GY), thousand-kernel weight (TKW), test weight (TW), percentage of grains per cob (% G/C), and grain humidity at harvest (GHH). The results indicated that yield was not negatively impacted by early or late sowing compared to the optimal date, with differences of 52 kg ha−1 between ES and OS, 147 kg ha−1 between ES and LS, and 95 kg ha−1 between OS and LS. ES increased TW (723.4 kg hl−1) and % G/C (86.7%), but reduced GY (13,377 kg ha−1), TKW (335.3 g), and GHH (19.5%). Conversely, LS positively influenced GY (13,524 kg ha−1), TKW (356.7 g), and GHH (23.9%), but negatively affected TW (692.8 kg hl−1) and % G/C (84.9%). Yield data obtained by P9900 and Kapitolis hybrids suggest that they are suitable for early sowing.
