Resumen

The study's objective was to evaluate the establishment and production of forage grasses and legumes in acidic and degraded soils of Puerto Bermúdez, Peru. Two treatments were experimented with, consisting of 3 grasses (Brachiaria decumbens, Andropogon gayanus and Brachiaria dictyoneura) and 12 legumes (Stylosanthes guianensis, Desmodium ovalifolium, Centrosema pubescens, Zornia latifolia, Stylosanthes capitata, Centrosema macrocarpum, Centrosema sp., Centrosema brasiliensis, Centrosema arenarium, Zornia glabra, Aeschynomene histrix, and, Pueraria phaseoloides), in monoculture plots, using a Completely Randomized Design, showing statistically significant differences. The grass that had the highest plant height (73 ± 0.01 cm) was Andropogon gayanus, dry matter (4,325 ± 435.88 kg ha-1), and the percentage of cover (100% m-2) was Brachiaria dictyoneura. The legume that stood out in plant height was Stylosanthes capitata (34 ± 0.01 cm), in dry matter, Stylosanthes guianens (2265 ± 294.95 kg ha-1), and, in percentage of cover (100%), Stylosanthes guianens stood out, Desmodium ovalifolium, Zornia latifolium, Pueraria phaseoloides, respectively. The study's findings highlight the significant differences in the performance of certain grasses and legumes in acidic and degraded soils and the need for further research on associated crops, fertilization, and agronomic management to fully exploit their potential.
