- Abstract
The objective of this study was to determine the effect of two plant densities and harvest frequencies on rose of china's forage yield and quality. The experiment was set in a randomized block design in divided plots (n=3), the larger plot corresponded to plant density (50,000 and 120,000 plants ha-1) and the smaller to harvest frequencies (6, 8 and 10 wk). The higher production (P<0.05) was found in the lower plant density and the longer harvest frequency (19.2 t DM ha-1) while the shorter (6 wk) harvest frequency and high plant density yielded 8.7 t DM ha-1. Protein leaf content was similar for all plant densities but showed differences (P<0.05) for harvest frequency, 21.6, 20.0 and 19.1 % for 6, 8 and 10 wk, respectively. Significant differences were found (P<0.05) for NDF in leaves in accordance with harvest frequency and plant density, the lower content (24.7 %) being for the 6 weeks harvest frequency and 50,000 pl ha-1 density and the higher for the 8 weeks harvest frequency and 120,000 pl ha-1 density (40.1 %). The best leaf average percentage (75.4 %) was found in the 6 weeks harvest frequency. As a conclusion, it can be said that the higher forage yield is obtained when harvested at 70 d frequency in a 50,000 plant ha-1 stand, although it's best nutritive quality does not concur with this frequency and plant density.
