This study investigates the effects of nitrogen fertilization on the productivity of soybean crops in Southern and Central Romania under changing climatic conditions. The research focuses on two soybean varieties, Amiata and Orakel, cultivated in the regions of Caracal and Crișcior, which differ in soil characteristics and environmental stressors. Field experiments were conducted using three nitrogen application rates, and key agronomic traits such as plant height, number of pods, grain yield, and seed quality parameters were measured. Although statistical analysis did not reveal significant differences across treatments, strong positive correlations between nitrogen levels and several performance indicators were observed. The findings underscore the importance of adaptive nitrogen management strategies for maintaining soybean productivity and resilience in climate-sensitive agricultural regions.
