Shade coffee farms promote genetic diversity of native trees
when caterpillars fed on fruit-bearing pepper plants. Here, although initially feeding on leaves, the beet armyworms soon moved into the maturing fruits (Figure 1C). Our results indicate that visiting honeybees provide plants with a totally unexpected advantage: bees flying around plants inhibit the feeding intensity of herbivorous caterpillars, resulting in a clear reduction of leaf damage. Th...
متن کاملTree biodiversity in farmer cooperatives of a shade coffee landscape in western El Salvador
Conservation of tropical biodiversity in agricultural landscapes has become more important as the area covered by natural ecosystems decreases. We analyzed the effects of local livelihoods, cooperative types, and selected biophysical variables (elevation, slope, percent shade, distance to the forest, coffee density, and coffee age) on tree biodiversity in shade coffee cooperatives of El Salvado...
متن کاملPotentials for Shade Management in Agroforestry Systems for Taro Cropping
This paper discusses the potential benefits from shade management in agroforestry systems for taro cropping. Trial work to evaluate weed growth, taro production, and cultivar responses to shade levels are reviewed. It is concluded that weed growth can be reduced in tree-shaded plots without reducing corm production. Higher crop biomass is obtained when taro is grown under fifty percent shade co...
متن کاملEffect of shade on Arabica coffee berry disease development: Toward an agroforestry system to reduce disease impact.
Coffee berry disease (CBD), caused by Colletotrichum kahawae, is a major constraint for Arabica coffee cultivation in Africa. The disease is specific to green berries and can lead to 60% harvest losses. In Cameroon, mixed cropping systems of coffee with other crops, such as fruit trees, are very widespread agricultural practices. Fruit trees are commonly planted at random on coffee farms, provi...
متن کاملWoody plant diversity and structure of shade-grown-coffee plantations in northern Chiapas, Mexico.
Shade-grown coffee is an agricultural system that contains some forest-like characteristics. However, structure and diversity are poorly known in shade coffee systems. In 61 coffee-growers' plots of Chiapas, Mexico, structural variables of shade vegetation and coffee yields were measured, recording species and their use. Coffee stands had five vegetation strata. Seventy seven woody species most...
