Abstract

This study analyzes sugar beet root yield, and sucrose content in Eastern Croatian in the period from 2018 to 2023. All agrotechnical measures were carried out properly. The sugar beet was sown in the optimal terms, from mid-March to the beginning of April. The relationship between temperatures, root yield, and plant protection in sugar beet production is critical for optimizing crop outcomes. The highest sugar beet root yield was in 2021 (95.6 t ha⁻¹) with the highest sucrose content (17.6%). In 2023, yields were low (40.8 t ha⁻¹), likely due to high summer temperatures. The average root yield over six years
was 75.0 t ha⁻¹ with an average sucrose content of 15.4%. In general, these research outcomes confirmed that the balance between appropriate sowing times, temperature management, and plant protection measures is crucial for maximizing root yield and sugar content.
