Soil is a plant growing medium that determines the sustainability of plants to grow and produce dry weight of forage. The experiment aims to determine the productivity of Asystasia gangetica (L) subsp. Micrantha was planted in different soil types and levels of shade. The experiment used a completely randomized design (CRD) split plot pattern with 2 factors. The main plot is the soil type, namely: Mediterranean soil (TM), Latosol soil (TL), and Regosol soil (TR) and sub plots are the levels of shade: N1: 20%, N2: 40%, and N3: 60%. Variables observed: plant height, number of leaves, number of branches, dry weight of leaves, dry weight of stems, total dry weight of forage, and leaf area per pot. The results showed that there was no interaction between soil type and different levels of shade on the productivity of Asystasia gangetica (L) subsp. Micrantha. Latosol (TL) soil type can increase the productivity of Asystasia gangetica (L) subsp. Micrantha and levels of shade 40% (N2) give the best results. It was concluded that there was no interaction between soil types and different levels of shade, latosol soil type and levels of shade 40% could increase the productivity of Asystasia gangetica (L) subsp. Micrantha.
