Potentials for Shade Management in Agroforestry Systems for Taro Cropping

Abstract

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 compared to full sunlight. Furthermore, there is a shade/cultivar interaction which indicates the need to select cultivars appropriate to the shade levels found in farmers' fields. Tree shade in agroforestry plots provides a pleasant environment to carry out heavy tasks such as crop planting and weeding, possibly improving productivity from labor.
