The location of plant growth can determine the growth and dry weight yield of forage achieved well. A growing place that is suitable for the type of plant planted is able to provide maximum and continuous forage. Research to determine the production and nutrient content of Asystasia gangetica (L.) subsp. Micrantha grown in different locations, using a completely randomized design (CRD) with 4 treatments and 9 replications. Treatment of Asystasia gangetica growing locations were: under banana trees (BP), on the road side (PJ), in the rice fields (PS) and on the coast (PT). The variables observed include: production variables, plant growth characteristic variables, forage nutrient content and soil nutrient content. The results of the research showed that the highest total dry weight production of Asystasia gangetica forage was obtained in the treatment rice fields (PS) growing locations of 21.19 g/m2 with crude protein content (24.19%), crude fiber (15.87%), gross energy (4,260 kcal/kg) and this result is supported by the highest soil nutrient content in the rice fields (PS) treatment. It can be concluded that the growing location of Asystasia gangetica (L.) subsp. Micrantha in the rice fields (PS) can increase the total dry weight production of forage and the nutrient content of forage.
