This study examines the phenology of different pea accessions from VRDS Buzău collection over four years (2020– 2023), focusing on the impact of climatic conditions on key phenophases: emergence, flowering, pod formation, harvest maturity, and physiological maturity. Temperature and precipitation significantly influenced both the duration of the crop cycle and yield potential. In 2020, emergence occurred 14–26 days after sowing, with harvest maturity at 65–96 days. High precipitation delayed harvest and reduced yield. In 2021, slower emergence (18–34 days) and extended physiological maturity (71–116 days) were observed. The 2022 season, characterized by extreme drought and strong winds, led to delayed emergence and lower yields., In contrast, 2023 experienced faster emergence and uniform maturation due to favourable weather condition. These findings highlight the critical role of climate monitoring in optimizing pea production. Understanding the relationship between environmental factors and crop development is essential for improving agricultural efficiency and ensuring yield stability.References
