Main Article Content


Java lemongrass is commonly cultivated in Vietnam for the food industry and traditional medicine. To achieve high productivity, the application of fertilizer is one of the most traditional farm practices and necessary. A single factorial experiment was carried out in a random-ized complete block design to investigate the effect of nitrogen fertilizer doses on growth, leaf and essential oil yields of Java lemongrass. Eight treatments were used in this experiment including 0, 15, 30, 45, 60, 75, 90 kg N/ha and applying only 2 tons Komic biofertilizer/ha as control. Fertilizer foundation for treatments 1 - 7 (for 1 ha) included 2 tonnes of Komix biofertilizer, 60 kg P2O5 and 60 kg K2O. The application of 90 kg N/ha significantly improved the growth of Java lemongrass and increased leaf yield (12.02 tons/ha/3 harvest times) as well as resulted in the highest oil yield (138.1 kg/ha/3 harvest times).
