Maize (Zea mays L.) is one of the most produced cereal crops on a global scale. The field experiment was held in the experimental of the selected area in region Razgrad (North-Eastern Bulgaria) during the period 2021-2023. The randomized complete block design with 4 replications and 25 m2 plot size was applied with five maize hybrids - P9415 (FAO 360); P9889 (FAO 420); P9903 (FAO 420); KAPITOLIS (FAO 380) and INTELIGENS (FAO 420). The purpose of the study was to establish the productivity and quality of some maize hybrids, grown in North-Eastern Bulgarian region. The following characteristics were reported: grain yield; cob length; number of rows per cob; number of grains per row; mass of grain per cob; 1000 grains weight; test weight and crude protein. The analysis of the results showed that the highest grain yield was obtained from P9889 hybrid due to the higher values of yield structural elements, while the highest values of the crude protein were reported by the hybrid INTELIGENS. The values of the indicators 1000 grains weight and test weight were highest by the hybrid KAPITOLIS (313 g and 74.2 kg, respectively).
