Abstract

Typha sp. plants are rustic and have accelerated development. However, their real growth and potential to animal nutrition are not so well-known. This study aimed to evaluate the shoot biomass production, growth dynamics and chemical-bromatological composition of Typha sp. plants at different cutting heights, under semiarid conditions. A total of four cutting heights (60 cm, 100 cm, 140 cm and 180 cm) were evaluated in a complete randomized design, with five replicates. Plants presented similar production of leaf biomass and heart of palm up to 140 cm height, with higher leaf accumulation above this value. Its heart of palm grows up to 112.5 cm and, above this height, only leaf elongation occurs. It is not recommended to cut this plant bellow 140 cm height, otherwise that can affect the pseudo-stem formation (heart of palm), which supports the leaf biomass accumulation.
