AGRONOMIC INDICATORS OF SILVER BLUESTERN (BOTHRIOCHLOA SACCHAROIDES) UNDER SIMULATED SHADE CONDITIONS IN THE MAGDALENA RIVER CALIDO VALLEY, TOLIMA, COLOMBIA

摘要

Silver Bluestern (Bothriochloa saccharoides) grass could be is a good feeding option managed under tropical silvopastoral systems, becausesince it is tolerant to a high degree of tree coverage; however, this grass has not been sufficiently studied. This study aimed to analyze agronomic indicators and other characteristics from of Bothriochloa saccharoides under two levels of simulated shade: 30%; 50% and total exhibition to sun radiation (0% of shade). Production of dry matter of the Bothriochloa saccharoides, duringin the humid season was 3.47, 3.0 and 5.56 ton/ha, and induring the dry season it was 2.33, 2.44 and 2.5 ton/ha, for the simulated coverage of 50%, 30% and control test, respectively. There are not significant differences (p = 0.05) between treatments; it, which suggests a potentiality from use for this grass to use it in pastures with trees. These results demonstrated a similar productive performance under different simulated shade conditions, that which makinges it a tolerant grass to the shade and a good option in silvopastoral systems.
