RESUMO

Chemical composition and dry matter (DM) productivity of 25 genotypes of sorghum were obtained. The experiment was carried out in a randomized block design with 25 treatments and three replications each. The data were submitted to analysis of variance and the means grouped by Scott-Knot Test (5%). The level of DM productivity varied from 6.82 to 14.17ton/hectare, and the higher level was obtained by VOLUMAX genotype (16.09 ton/hectare). The levels of crude protein varied from 5.24 to 7.79%. No differences were detected between the genotypes to neutral detergent fiber levels, which varied from 59.03 to 73.04%. Considering the level of acid detergent fiber, the variation interval was 26.78 to 40.92%. The better genotypes for silage production were ATF54*9929036, CMSXS212*9929048, CMSXS217*9929012, and VOLUMAX.
