The dynamic nature of crop cultivation technologies necessitates continuous adaptation to environmental conditions, new varietal characteristics, and logistical advancements to optimize growth and development conditions for pea plants. Modern climate change and fluctuating weather patterns demand high adaptive potential in pea varieties to recover metabolic processes following stressors. Each variety exhibits critical thresholds for biotic and abiotic stress tolerance. In dry years, the pea growing season may shorten by up to 10 days, reducing productivity. The typical growing season for spring peas in the forest-steppe zone ranges from 75 to 105 days, extending to 140 days in very late-ripening varieties. This study aimed to assess the effects of agrotechnical measures on the growing season of peas in the right-bank Forest-Steppe region from 2020 to 2024. Field experiments were conducted using the Hambit and Eso pea varieties. Observations revealed that the growing season ranged from 76 to 88 days, depending on meteorological conditions, seed treatments, and foliar nutrition. Positive impacts on interphase periods and the overall growing season were observed with the application of mycorrhizal preparations and inoculants. When fertilized with Mikofrend in combination with inoculants, the Eso variety exhibited a growing season of 79–84 days, while the Gambit variety ranged from 80–83 days. Foliar applications of microfertilizers further extended the growing season, reaching 82–86 days for Eso and 83–88 days for Hambit. Phenological studies confirmed that seed treatments with mycorrhizal preparations and inoculants extended the growing season by 6–8 days. The use of Nais and Avanhard microfertilizers contributed an additional 2–3 days of growth, depending on the variety. These findings highlight the importance of agrotechnical measures, including mycorrhizal preparations, inoculants, and microfertilizers, in extending the growing season and optimizing pea productivity under changing environmental conditions.
