| الوصف: | This study aimed to evaluate the efficiency of Mombasa grass in a silvopastoral system and submitted to different nitrogen fertilization rates and pasture management strategies. Treatments consisted of four nitrogen fertilizer doses (0.0, 125.0, 187.5, and 250.0 kg N ha-1 year-1) and three cutting heights (70, 90, and 105 cm). Plant agronomic and physiologic efficiencies, as well as nitrogen use and accumulation by plants, forage production, and increments of forage production, were verified for the application of nitrogen fertilizer. Nitrogen fertilization was only efficient for grasses cut at 105 cm, where 75% of the applied nitrogen at a dose of 125 kg ha-1 year-1 was recovered. Yet the grasses cut at 70 and 90 cm presented low results for nitrogen fertilization, showing plants with low physiological and agronomic efficiencies. For Mombasa grass in a silvopastoral system, nitrogen fertilization is more efficient when applied at lower doses and for plants cut at higher heights. |
