Abstract. The aim of the development is (through two-way dispersion analysis - ANOVA) to study the impact of the factors “year characteristics” and“fertilization levels” on the separate biometric indicators for wheat: ear length (cm), ear-bearing stems (cm), number of grains per ear (num.), grain weight perear (g) and mass of 1000 grains (g). Data for the yield and its structural elements were used. They were obtained through a field experiment conducted in theperiod 2009 – 2011, on a meadow-cinnamon soil in the experimental field at Agricultural Institute – Stara Zagora. With high degree of reliability the impact of theexamined factors and their interaction on the following indicators was statistically proven: length of wheat-ear (cm), ear-bearing stems (cm), number of grainsper ear (N), grain weight per ear (g), mass of 1000 grains (g). The strongest impact on the given factors has the factor “fertilization levels” for the indicator “earbearingstems” (96%).
