Peas are a key leguminous crop in Ukraine due to their valuable properties, which are beneficial for both agriculture and ecology. Pea grain is widely used in the food industry, serves as an important component of animal feed, and acts as a natural nitrogen fixer, improving soil fertility. These characteristics ensure its important role in enhancing the productivity of agricultural systems and supporting agroecological stability. Climate change, particularly warming and uneven rainfall distribution, presents challenges for growing traditional crops, including spring peas. As a result, the development of winter pea varieties becomes a promising solution. These varieties better utilize moisture during the late autumn and early spring periods, provide more stable yields, and protect the soil from erosion. This is especially important for regions at risk of soil degradation, such as the southern regions of Ukraine. The article presents the results of numerical calculations of the productivity of winter peas under the agrometeorological conditions that prevailed in 2023, compared to the agroclimatic conditions expected for 2031-2050. The obtained results confirm the potential of growing winter pea varieties as a strategy for adapting Ukrainian agriculture to climate change, as it increases yield, preserves soil, and ensures the stability of agroecosystems.
