Abstract
Five maize hybrids with different maturity and FAO-number (350, 380, 420, 490 and 510) were tested at the Látkép Experiment Site of the University of Debrecen. In 2022, an especially drought year, the rainfall deficit (456 mm) was compensated by irrigation. A large number of measurements were taken to record plant height, thousand grain weight, leaf area index, and ear parameters. The highest yield was obtained with the FAO 420 hybrid (H-11), 18.397 t ha-1. The results of the FAO 350 (H-9) and FAO 380 (H-10) hybrids (15.657–15.678 t ha-1) were identical. The yields of the hybrids FAO 490 (H-12) and FAO 510 (H-13) were significantly different (14.973 and 17.395 t ha-1). The obtained research results show that yields are mainly determined by the thousand grain weight.
