Results of stand studies on the vertical and horizontal pressure of triticale grains with different moisture content (u1 = 0.212 and u2 = 0.245 kg kg-1 d.b.) in silos of H/D1 = 15 and H/D2 = 8 slenderness are presented in this study. Duration of each experiment was 10 days. It was found out that an increase of moisture content caused higher pressure both on the sides and bottom of the silo. Slenderness affected pressure values as well. Pressures were higher in a thickset silo than in slim one. Pressures exerted by triticale to the silo bottom were significantly higher than those exerted to the sides. The highest increase of the parameters under study was found during the first five days of triticale storage. Triticale was bridged only in thickset silo (in its upper part) during storage with the grain of moisture content u2 = 0.245 kg kg-1 d.b. between the 6th and the 10th day.
