“…Piatã) was grown in monoculture or in association with trees (Eucalyptus sp.) planted at different densities (181 and 718 trees/ha) and managed under rotational grazing, the importance of light as the determining factor of plant growth and responses was corroborated and expanded, since plant morphogenetic and population dynamic responses were strongly influenced by the amount of photosynthetic radiation available [102]. Under those conditions, a wide range of light availability was generated through regrowth interval, tree density, distance from the tree rows, and season of the year (in this case representing the varying solar angle from summer to winter), illustrating the key role played by light availability within the sward in determining plant growth and herbage production.…”

Grazing management has been the focus of the research with forage plants in Brazil for many years. Only in the last two decades, however, significant changes and advances have occurred regarding the understanding of the key factors and processes that determine adequate use of tropical forage plants in pastures. The objective of this review is to provide an historical overview of the research with forage plants and grasslands in Brazil, highlighting advances, trends, and results, as well as to describe the current state of the art and identify future perspectives and challenges. The information is presented in a systematic manner, favoring an integrated view of the different trends and research philosophies. A critical appraisal is given of the need for revision and change of paradigms as a means of improving and consolidating the knowledge on animal production from pastures. Such analysis idealizes efficient, sound and sustainable grazing management practices necessary to realize the existing potential for animal production in the tropics.

“…En algunos estudios se ha evaluado el crecimiento de cultivos forrajeros mediante el análisis del porcentaje de intercepción de luz recibida por el dosel vegetal (Gobbi et al, 2009;Crestani, 2015), además de otras variables que se correlacionan con la producción de forraje y su estructura, como la altura de la pradera y el índice de área foliar (Hammer et al, 2002).…”

La productividad de una especie forrajera puede ser descrita en términos del comportamiento de sus componentes morfológicos y la combinación con el ente en la pradera. El objetivo fue evaluar el comportamiento productivo de trébol pata de pájaro (L. corniculatus), bajo diferentes estrategias de defoliación. El experimento se llevó acabo en el Colegio de Postgraduados de septiembre 2015 a septiembre de 2016, en un diseño de bloques al azar, con tres repeticiones, con la hipótesis, que al cosechar la especie al 95% de luz interceptada (LI) se tiene un mejor comportamiento productivo. Un intervalo de corte fijo (CF), tuvo menor producción en invierno (3 441 kg MS ha-1), verano (5 024 kg MS ha-1) y anual acumulado (20 710 kg MS ha-1), respecto al resto de los tratamientos (26 689 kg MS ha-1, promedio anual). También, manifestó menor altura de planta (21 vs 26 cm, promedio en la LI). No obstante, el CF tuvo mayor relación hoja: tallo, tanto estacional como promedio anual (2.3 vs 1.5 promedio en la LI). Los valores estacionales más altos fueron en otoño e invierno (1.9). En primavera y verano se presentaron las alturas mayores con 29 cm vs invierno con 19 cm. La hoja aportó 51% al rendimiento anual, seguida por el tallo, maleza y material muerto con 32, 10 y 6%, respectivamente. En conclusión, el mejor comportamiento productivo de trébol pata de pájaro, genotipo 260012, se presentó en las estrategias de cosecha de LI respecto al CF.
