Performance of three Centrosema spp. and Pueraria phaseoloides in grazed associations with Andropogon gayanus in the Eastern plains of Colombia
Centrosema acutifolium Benth., a native legume of acid-soil savannas, associated effectively with Andropogon gayanus Kunth var. bisquamulatus (Hochst.) Hack. cv. Carimagua 1 en the Eastern Plains (Llanos Orientales) of Colombia. The persistence of C. acutifolium was attributed to its stoloniferous growth habit. This legume exhibited tolerance to grazing and drought and has resistance to pests and diseases. The four legumes evaluated under grazing failed to produce soil seed reserves for recruitment of new plants and this contributed to the general decline in legume contents. Pueraria phaseoloides (Roxb.) Benth. showed poor tolerance to drought and C. macrocarpum Benth. was adversely affected by grazing and low soil fertility. C. arenarium Benth., the least palatable species in the experiment, has proved to be unsuitable for grazing utilization
