Abstract

This experiment was conducted at the
Alfredo Volio Mata Dairy Cattle Experiment Station in Costa
Rica, at an altitude of 1542 masl, with an average annual
rainfall of 2050 mm, temperature of 19.5°C and a relative
humidity of 84%. A ramie plantation was split into four
blocks, with a distance of 70 cm between rows and 50 cm
between plants. Each block was divided into four plots given
consecutive pruning treatments every 42nd , 56th, 70th and
84th day. The annual yield of bio-mass of the whole ramie
bush (stems and leaves) was highly influenced (P=0.01) by
the cutting frequency. The stem production and the whole
plant had a non-linear response when the cutting interval
increased between the 42nd to 84th day. The leaf:stem ratio
showed a decrease as the pruning interval increased. The
ability of the plants to re-grow was observed however, in
subsequent prunings there was a low persistence on
production.
