During the agricultural years 2020-2022 at SCDA Braila, experiments with maize hybrids have been placed in which the growth and development processes as well as the productivity of Felix, Iezer and F423 maize hybrids have been followed. In the climatic context of 2020, the growing cycle was staggered over a period of 159 days (10.04.2020-16.09.2020), during which time precipitation totalled 162.4 mm, accumulating a useful temperature of 3254°C. In 2021, the growing cycle was staggered over a period of 147 days (05.05.2021-29.09. 2021), during which period rainfall totalled 335.5 mm, accumulating a useful temperature of 3038.6°C, and under the conditions of this year, 2022, maize sown on 28.04.2022, covered 151 days to reach harvest maturity on 26.09.2022 under the conditions of accumulating a useful temperature required to cover the growth and development phenotypes of 3270°C. Yields recorded in the three crop years for the three hybrids ranged from 7.24 t/ha to 11.66 t/ha for hybrid Felix, from 7.48 t/ha to 9.95 t/ha for hybrid Iezer and from 8.96 t/ha to 11.80 t/ha for hybrid F423.
