BASTIDAS, Luis et al. Perfomance of five sugarcane varieties for forage yield in the Santa Cruz Valley of Bucaral, Falcon state, Venezuela. Zootecnia Trop. [online]. 2010, vol.28, n.3, pp.303-312. ISSN 0798-7269.

Five varieties of sugarcane (Saccharum sp. Hybrid): B80-549, CR74-250, V71-39, B80-408 and PR 61-632 were evaluated for forage yield and leaf/stem ratio in different cutting ages (4, 8, 12 and 16 months) and harvest cycles at the Santa Cruz Valley of Bucaral, Venezuela. The study was conducted using a randomized block experimental design with split plot arrangement. The statistical analysis showed that the largest values of leaf / stem ratio (L / T) were observed in varieties B80-549, CR74-250 and PR61-632. The highest values of green forage ton per hectare (TMVH) were obtained in B80-549, PR61-632 and CR74-250, and the highest yields in TMVH.year-1 were obtained at 12 months, followed by the performance at 8 months. These varieties could be used in sustaining a high amount of animal units per hectare
