GARCIA ROMERO, Ibonne Aydee et al. Agronomic evaluation of natural rubber associated with three natural coverages in the altillanura. Colomb. for. [online]. 2020, vol.23, n.1, pp.94-108. ISSN 0120-0739.  https://doi.org/10.14483/2256201x.14996.

The purpose of this research is evaluating the results of the effect of M. bracteata, Desmodium sp y P. phaseoloides cover crops in growth, and their influence in the phytosanitary conditions of a two years old natural rubber crop in the “Altillanura Colombiana”. We established treatments by cover crop with three repeats and a control crop. The development of the trees was evaluated through the measurement of perimeter and total height. Additionally, inoculations of C. gloesporioides were carried out in the three cover crops under semi-controlled conditions. It was found that the three cover crops generated a slight increase in the organic matter of the soil and have a favorable effect on the development of the trees. Also, that the most frequently isolated fungi corresponded to Cladosporium sp., E. sorgui and Fusarium sp., and that the inoculations showed that the three coverages are susceptible to C. gloesporioides.
