Abstract
the annual biomass production of Tithonia diversifolia collection 10. A random block design in factorial arrangement with four repetitions
was applied in each experiment to analyze the following factors: plantation distance (0.5 and 1.0 m) and cutting height (5, 10 and 15 cm) (experiment 1 A); cutting frequency (40, 60 and 80 d) and cutting height (5, 10 and 15 cm) (experiment 2 A). There was interaction for
the factors under study. During the rainy season, there was higher yield (P < 0.001) in the experiment 1 with the lowest plantation distance (5.0 ? 5.5 t/ha DM) and there was no effects in respect to the cutting height. The lowest plantation distance in the dry season had better performance in respect to yield (3.5-4.5 t/ha DM) and there was effect of the cutting height with lower yield (3.5 t/ha DM) at 5 cm (P< 0.01).
In the experiment 2, the best performance (P< 0.001) was at 10-15 cm height and frequency of 80 d during the dry season (0.85-0.90 t/ha
DM). The cutting height of 15 cm had (P< 0.001) the best yields together with the frequency of 60 d for the rainy season (1.7 t/ha DM).
Higher yield was reached at distances of 0.50 m between furrows for both seasons. The plantation should be cut at heights between 10 and
15 cm, with cutting frequency of 60 and 80 d in the rainy and dry season, respectively.
Key words: plantation distance, cutting frequency, cutting height, biomass production.
