ABSTRACT
Lemongrass (Cymbopogon citratus) also known as tanglad has many uses in the medical, cosmetic, food and other industries because of its essential oils which contain citrate which has antibacterial, anti fungal and antioxidant properties. Thus, this study aimed to identify which lemongrass planted in the different soils we obtained from the four different provinces in Panay would yield the greatest amount of essential oil for a period of 60 days. After harvesting the plants were subjected to steam distillation to acquire the essential oil which was measured in mg/g of plant matter and the soils were measured for their pH, organic matter, potassium and phosphorus content. The results showed that the plants planted on soils from Aklan, Antique, Capiz and Iloilo yielded 24.6, 25.66, 23.2 and 23.86 mg/g plant matter respectively however there was no significant difference among the amounts. Therefore it is not significant to choose which soil the lemongrass will be planted on.
