Abstract:
The objective was to evaluate an analysis of growth of grass Mulato II (hybrid Urochloa) by varying the intensity and obtaining the optimal cutting moment in the dry and rainy season. The evaluated variables were: forage yield, morphological composition, plant density, plant height and intercepted relationship. The best dry matter yieldwas obtained at 56 days in rain, at an intensity of 15 cm, 1,820 kg DM ha-1andthe lowest at 7 days of regrowth in the dry season, with intensity 10 cm and a yield of 200 kg DM ha-1. The highest plant density was in the dry season and lowest in rain with 9.5 and 8.5 plants m-2, respectively. 95% of intercepted radiation was obtained at 70 cm of plant height, in the rainy season, at 15 cm of cutting intensity and with 42 days of regrowth. The grass Mulato II should be cut between 35 and 42 days after the regrowth, at an intensity of 15 cm, since that is when the best structural characteristics and the highest intercepted radiation are found (95%)
