| Con el objetivo de cuantificar las diferencias en el rendimiento anual y estacional de forraje y la velocidad de crecimiento de dos gramíneas y una leguminosa en función al manejo estacional de la frecuencia de pastoreo, se realizó el presente estudio en el campo experimental del Colegio de Postgraduados, en Montecillo, Texcoco, Estado de México, en una pradera asociada en su segundo año de establecimiento. Se evalúo el rendimiento de forraje, altura de planta (cm), radiación interceptada (RI, %) y composición botánica del forraje cosechado (% y kg MS), dinámica de rebrote, tasa de aparición, tasa de muerte y tasa de sobrevivencia de tallos (DPT, TAT, TMT, TST). Los tratamientos fueron las asociaciones 100:00:00, 00:100:00, 20:40:40, 00:50:50, 40:20:40,... |

| ABSTRACT This study was carried out to evaluate the effect of nitrogen fertilization on tillering dynamics of Alexandergrass (Urochloa plantaginea (Link) Hitch) grazed by beef heifers in a rotational stocking grazing method. The experiment was conducted in a completely randomized design following a repeated measure arrangement, three levels of nitrogen (Zero, 150 and 300kg ha-1) and two area repetition. The classification of tillers into categories (basal and axillary) showed a greater number of basal tillers, due to their higher appearance rate, in the absence of nitrogen fertilization. Nitrogen fertilization promoted higher axillary tiller density. The use of nitrogen promotes the renewal of axillary tillers of Alexandergrass, without compromising the... |

| ABSTRACT: The silvopastoral system has been suggested as an alternative to recover degraded pastures in tropical regions. However, trees reduce the light available for pastures, which may affect the growth and herbage accumulation. The objective of this study was to evaluate the morphogenesis, canopy structure and herbage accumulation of signalgrass ( Brachiaria decumbens ) subjected to three light regimes (0, 20 and 70% of natural shading) and two fertilization levels (presence or absence of nitrogen, phosphorus and potassium). Leaf and stem elongation rates increased under shading but did not vary with fertilization. The leaf appearance rate was greater under fertilizer treatment but was generally similar among light regimes. The tiller density was... |
