ABSTRACT
The experiment was conducted with the purpose of evaluating the production parameters of the plant and the production cost of silage from different sorghum hybrids: AGX-213 and 2002 (forage); AGX-217 and AG-2005E (double-purpose). The AG-2005E hybrid was the most precocious with 130 days between sowing and harvesting, while the AGX-213 was the latest with 158 days. The plants of the forage hybrids AG-2002 were taller and showed higher dry matter production than the forage hybrid AGX-213 and than the double purpose hybrids AGX-217 and AG-2005E. The AG-2005E hybrid plant showed higher panicle percentage (45.6%) and lower percentages of stem (26.2%) and leaves (28.2%), while the forage hybrids AGX-213 and AG-2002 showed higher stem percentage, (48.1% and 49.6%, respectively). The analysis of the composition of plant showed that the panicle had higher dry matter content than the stem and leaves components.
