Indicadores de la composición química en caña de azúcar según edad de rebrote, cultivar y fracción de la planta.

The goal of this paper was to assess the behavior of chemical composition indicators (dry matter, ash, gross protein, phosphorous, and potassium) of two new sugar cane varieties, based on plant fractions and re-shoot age. Chemical analyses were made to several plant fractions (whole, nodes, stem) at different re-shoot ages (six, eight, and eleven months). Forage variety My5514 was used as control. Multifactorial variance analyses were also made. The results demonstrated that the chemical composition indicators of ash, gross protein, phosphorous, and potassium in sugar cane, depended on the age of re-shoot, variety, and plant fraction. Dry matter also depended on the re-shoot age and plant fraction. [ABSTRACT FROM AUTHOR]
