- Abstract
Climate change, through continuous rising temperatures and variability in rainfall, is a challenge for agriculture. Adapting some agricultural practices and technologies to the new environmental conditions can be one of the effective methods to reduce the effects of climate change. In this context, during 2020-2022 at Agricultural Research and Development Station Turda an experience with 7 maize hybrids was placed (Turda 248; Turda 165; Turda 201; Turda Star; Turda 332; Turda 344; Turda 335), which were sown in 3 different sowing dates (at 6℃, 8℃ and 10℃ in the soil), following the effect of the time of sowing on the development of the maize crop but also the impact of the environmental conditions on the yield. During the research period, the number of days from sowing to emergence, the emergence of the panicle, respectively the physiological maturity, was higher in the case of the first sowing date. The sum of useful thermal degrees (SUTG) (Σº≥10℃) was inversely proportional to the number of days for each physiological stage. The yield obtained by the 7 hybrids used was higher for the hybrids from the FAO 380 maturity group. The greatest increases in yield were recorded in the third age, but some hybrids performed better in the second sowing season. In the specific conditions of the Transylvanian Plateau, sowing maize earlier, even if it manages to avoid the negative impact of stress factors during the growing season, does not contribute to increasing of yield.
