The most important stage in the life cycle of any plant is emergence. Only after that can it be said that it has a chance to reach maturity and produce. A bifactorial experience: factor A – hybrid with 6 graduations: P 8834, P9398, P9889, P9944, P0450, P0710) and factor B – sowing time – with 2 graduations: 27.03.2024 and 16.04.2024, was placed on the chernozem of Caracal, in 2024. The hybrids were grouped in pairs and are part of three FAO groups (300-350, 350-450, and 450-500). The aim of the paper was to establish the influence of the sowing date on the elements of productivity and production.
In 2024, yields were extremely low (maximum 2600 kg/ha) but above the average yields obtained in Oltenia (500-800 kg/ha). While the hybrids of the FAO 300-350 group obtained higher yields by approximately 500 kg/ha in the first period, the hybrids in the following groups obtained lower yields by 500-550 kg/ha, and 230 kg/ha respectively, compared to the second period. Regardless of the hybrid, yields are almost identical at the two sowing dates.
