Sweet corn is a crop highly sensitive to climatic conditions, which raises scientific interest in its productive indicators under climate change conditions. This study presents a comparative analysis of four promising hybrids for Bulgaria – Zeaton F1, Turbo F1, HMX5389 F1, and HMX59YS832 F1. The experiments were conducted in 2023 and 2024 on the territory of the Agricultural University of Plovdiv. The results show significant differences between the hybrids, with Zeaton F1 exhibiting the best biometric indicators and a maximum plant height. Plant development and especially critical periods coincided with stressful summer conditions. The second year was characterized by more extreme climatic events, but late sowing reduced the negative impact on yield. It was established that growing sweet corn in the dry conditions of Plovdiv is impossible without irrigation, while drip irrigation significantly improved moisture reserve. Hybrids with a shorter growing season showed better growth parameters when sown late. A strong correlation was observed between plant height and the number and length of leaves.
