Cultivo asociado de plantas aromáticas con café (Coffea arabica L.) bajo condiciones de invernadero y campo
Resumen
Most of the natural products that cause allelopathy are compounds of secondary metabolism synthesized by plants and microorganisms, and most of those currently identified are present in aromatic plants. The allelopathic and auto-toxic effects of coffee plants are well known due to the production and accumulation of caffeine in a soluble form in soil. Intercropping aromatic plants with coffee provides some advantages such as weed control, the recycling of nutrients, low external-input farming, and extra income for the idle area, but allelopathic interactions must be identified. The results obtained in this study did not show that either the age of crops, or the accumulation of caffeine in the soil, had a negative influence on the yield of aromatic plants. Potential detoxification of caffeine through sage, thyme, and rosemary may diminish toxic accumulation of the allelochemicals in old coffee plantations and therefore increase production. Results demonstrated the high potential of intercropping coffee with spearmint, basil, and oregano to increase yield production as it reduces idle area, and increases profit margins for small coffee producers.
