The Effect of Altitude, Mulch, and Seedling Amount on Growth and Oil Content of Lemongrass

Lemongrass (Cymbopogon citratus) is a plant that can grow in extreme conditions such as lack of nutrient, alkaline soils, and steep slopes. Lemongrass has great potential to be developed extensively because lemongrass has many advantages, one of the example is the oil content of lemongrass can be used as a botanical plant to support organic agriculture. The aim of this research is to find the effect of altitude on growth and oil content of lemongrass, effect of plastic mulch (Black Silver), and the effect of seedling amount on lemongrass growth.
Lemongrass grows at an altitude of 50-2700 m above sea level, and can grow in poor soil nutrient. Therefore it is necessary to find the most suitable planting location so that plants can grow and develop optimally, as well as the ideal location to produce more oil contents. The results showed that the interaction L3M1 (lowland cultivating location by using mulch) produce maximum plant height, while the interaction L3B2 (lowland cultivating location with 2 seedling/planting hole) produce maximum plant height. Planting location affect the yields of dried plants destilation, lowland cultivating (Megati) location was found the highest distillate yield (oil), and high land planting (Bedugul) location give the lowest distillate yield (oil).
