In 2024, a bifactorial experiment was set up on the chernozem of Caracal, where A factor was the species: wheat, triticale, barley and B factor was the vegetation period: early, medium, late. The yield and flag leaf area were determined for each combination of factors in 3 repetitions. The highest yield was obtained for wheat – 61.92 q/ha. Compared to the control - yield of wheat species, only barley was significantly lower. There were no differences in yield between the vegetation periods, regardless of the species. The correlation coefficient between yield and flag leaf area recorded a value of 0.331, lower than the P5% limit for 27 studied cases, therefore insignificant. There were both varieties with small flag leaf area but with high yields (such as: medium-early triticale with flag leaf area of 1307.27 cm2 and yield of 68.54 q/ha and late wheat with area of 1840.27 cm2 and yield of 68.25 q/ha) but also varieties with large flag leaf area and high yields (such as: medium-early wheat with flag leaf area of 2951.07 cm2 and yield of 66.08 q/ha).
