Intercropping Tuber Crops with Teak in Gunungkidul Regency, Yogyakarta, Indonesia

The adoption of agroforestry system aims to combine food production enhancement compensate population growth with the improvement agricultural marketable products increase household income. diversification crop requires more effective land use. In Gunungkidul, high-density teak (Tectona grandis) plantation has dominated many private forests. area under tree crown received low light intensity, where only shade-resistant plants can survive. Tuber crops, i.e., arrowroot (Maranta arundinacea), canna (Canna edulis) and yam (Dioscorea esculenta) are shade-tolerant which were planted in understory for supplementary income generation. cultivation stand been overlooked due uncertainty tuber productivity. To address this knowledge gap, effect shade (5- 7-year teak) on yield three crops was examined. results indicated that both trial areas (with RLI 45.13% 38.76%) suitable (LER > 1), while management options recommended enhancing production. LER intercropped three-tuber 5 years’ >1, those 7 teak, reached >1. Canna is preferred option be mixed systems intensity its consistent yields, whether open or shade. Silvicultural management, pruning thinning growing space resource sharing plants. Land optimization forest using tubers will offer medium-term benefits, provided proper silvicultural procedures applied.
