Abstract
Three maize hybrids of different ripening periods and FAO numbers (350, 450 and 550) were examined at the Látókép Experiment Site of the University of Debrecen. The precipitation deficit was compensated by irrigation in the extremely drought year of 2022.
When evaluating the yield of the maize hybrids, it was found that the hybrids with higher FAO number produced more yield. Compared to the yield of the FAO 350 hybrid (14.241 t ha-1), the FAO 450 hybrid yielded 12% more and the FAO 550 hybrid 13.3% more significantly.
When grain moisture values were analysed, a similar correlation was found, with higher grain moisture associated with higher yields. It was found that, compared to the grain moisture of the FAO 350 hybrid (15.1%), the FAO 450 hybrid showed significantly higher values by 7% and the FAO 550 hybrid by 29%.
Based on the quality analysis of maize grain, it was found that the protein content, in contrast to yield and grain moisture values, was reliably lower as the FAO numbers increased. Compared to the protein content of the FAO 350 hybrid (7.27%), the FAO 450 hybrid achieved 14% and the FAO 550 hybrid 18% lower values. Oil content did not differ significantly between hybrids with different FAO numbers (3.82; 3.54 and 3.14%). Starch content was 2–3% higher in the higher FAO hybrids, but the difference was not significant.
