Four experimental hybrids and two commercial Sorghum bicolor cv bicolor x Sorghum bicolor cv sudanense hybrids were evaluated regarding the following agronomical characteristics: green matter production per hectare, dry matter production, plant height, plant number per hectare, regrowth rate and leaf/stem ratio. Plantings occurred in the dry–rainy transition period. The hybrids were submitted to three successive cuts and two planting periods. A randomized blocks experimental design was used and the means were compared by the SNK test (P0.05) to the commercial hybrids AG2501C (control), with 780.000 plants/ha, and to BRS800, with 749.000 plants/ha, and superior to the other hybrids. The productivity results indicated the potential of utilization of the studied sorghum-Sudan grass hybrids as an alternative for the cut forage production, in the transition period from dry to rainy season.
