The availability of forage in the rainy season is very abundant, in contrast to shaded areas which have constraints in the form of low light intensity which can reduce the production of dry forage matter. Research to determine the effect of different shade levels on the growth and yield of Asystasia gangetica (L.) subsp. Micrantha. The experiment was carried out for 6 weeks, using a completely randomized design (CRD) with 4 treatments and each treatment was repeated 15 times. Shade level treatment using paranet: N0: 0% (without paranet); N1: 20% (1 layer of paranet); D2: 40% (2 layers of paranet); and D3: 60% (3 layers of paranet). The variables observed were growth variables, yield variables and plant growth characteristics. The results showed that 20% shade treatment was able to increase the growth and yield of Asystasia gangetica (L.) subsp. Micrantha, while treatment with 40% and 60% shade levels reduced the growth and yield of Asystasia gangetica (L.) subsp. Micrantha. It can be concluded that 20% shade level is able to give the best results in increasing the growth and yield of Asystasia gangetica (L.) subsp. Micrantha.
