AB  - Knowledge of mechanical properties of agricultural materials is important for designing and exploitation of agricultural machines and equipment, as well as for successful preservation of biological values of seed during drying, processing and storage. As the shape of soybean seeds is generally round, they can be graded by a simple procedure, using different sieve settings. In this study we assessed the impact of seed grade on the mechanical properties of seed of the soybean varieties which differed in seed size. The initial tangent modulus of elasticity and maximum rupture force were used as indices of mechanical properties of seed, and they were discussed in detail in the paper. The values of the initial tangent modulus of elasticity went down as seed size increased. The lowest value, 9.26 N/mm2, was recorded for grade 6.0 to 6.5 mm in the variety Balkan. The highest value, 18.84 N/mm2, was recorded for grade 4.0 to 4.5 mm in the variety Victoria. Unlike the values of the initial tangent modulus of elasticity, the values of maximum rupture force increased in proportion with increase in seed size. The highest value, 176.18 N, was recorded for grade 5.5 to 6.0 mm in the variety Victoria, and the lowest value, 92.15 N, was recorded for grade 4.0 to 4.5 mm in the variety Balkan. .
AB  - Poznavanje mehaničkih osobina poljoprivrednih materijala je veoma važno prilikom konstruisanja i eksploatacije poljoprivrednih mašina i opreme ali je neophodno i za očuvanje bioloških vrednosti semena prilikom sušenja, skladištenja i procesa dorade. Seme soje na osnovu fizičkih osobina ima okruglast oblik pa je moguće kalibraciju uraditi jednostavnim postupkom pomoću sita raznih dimenzija i otvora. U radu je ispitan uticaj frakcija na mehaničke osobine semena soje za sorte koje se karakterišu različitom krupnoćom zrna. Kao pokazatelji mehaničkih osobina semena korišćeni su početni tangentni modul elastičnosti i maksimalna sila razaranja koji su detaljno prikazani u radu. Vrednosti početnog tangentnog modula elastičnosti su sa povećanjem dimenzije zrna imale manje vrednosti. Tako je najmanja vrednost zabeležena kod sorte Balkan za frakciju 6,0-6,5 mm od 9,26 N/mm2, dok je najveća vrednost zabeležena kod sorte Victoria za frakciju 4,0-4,5 mm od 18,84 N/mm2.Za razliku od početnog tangentnog modula elastičnosti, vrednosti maksimalne sile razaranja su se povećavale sa povećanjem dimenzija semena, tako da je najveća vrednost zabeležena kod sorte Victoria za frakciju 5,5-6,0 mm od 176,18 N dok je najmanja vrednost zabeležena kod sorte Balkan za frakciju 4,0-4,5mm od 92,15 N. .
