A pot culture study was undertaken to assess the allelopathic compatibility of leaves of certain homestead trees, viz. coconut (Cocos nucifera L.), cashew (Anacardium occidentaleL.), jack (Artocarpus heterophyllus Lamk.), mango (Mangifera indicaL.), tamarind (Tamarindus indica L.) and teak (Tectona grandisL.f.), commonly planted in the home gardens of Kerala, when applied as mulch in turmeric (cv. Sobha). At 6 months after planting (MAP), the number of leaves was significantly less in plants mulched with leaves of coconut, mango and teak. Rhizome yield was significantly higher when mulched with cashew (660 g plant-1), jack (557 g plant-1) and teak (565 g plant-1) leaves. However, mulching with mango leaves resulted in significantly lower yield (346.7 g plant-1). These findings will be useful for farmers in selecting suitable tree leaves for mulching in turmeric and also laying out compatible tree-crop combinations in their homesteads.align="justify">Downloads
