The study took place at the Alfredo Volio</p><p>Mata Experimental Station of the University of Costa Rica.</p><p>The first samples were taken at 91 days and were re-taken</p><p>every 14 days until they were 161 days old. Biomass</p><p>production was measured and the content of dry matter, crude</p><p>protein, ashes, neutral detergent fiber increased as the</p><p>maturity of the plants increased, to a rate of 0.19%/day in</p><p>leaves and 0.26%/day in stems, for a 0.22%/day in the whole</p><p>plant. The yield of green matter reached its maximum at 135</p><p>days, the leaves at 121 days, and the stems at 144 days. The</p><p>maximum production of dry matter, crude protein and neutral</p><p>detergent fiber per hectare was obtained from shoots of 130</p><p>to 135 days old. The best quality was found at 91 days, with</p><p>12% of dry matter and 14% crude protein. From that age on,</p><p>the accumulation of dry matter increased at a rate of 62</p><p>kg/ha/day (a concentration of 2% every 10 days), of which 48</p><p>kg were of neutral detergent fiber and an average of 2 kg of</p><p>lignin. The content of crude protein decreased 1% every 10</p><p>days.</p>}, number={1}, journal={Agronomía Mesoamericana}, author={Boschini-Figueroa, Carlos and Elizondo-Salazar, Jorge Alberto}, year={2005}, month={Apr.}, pages={29–36} }
