Effects of two in-organic fertilizers on volatile oil and biomass yields of Cymbopogon citratus (dc) stapf., in ile-ife, Nigeria

Abstract

Cymbopogon citratus (DC) Stapf (Poaceae) was cultivated in a randomized completely block design experiment, (RCBD) in Ile-Ife, Nigeria. Effects of two inorganic fertilizers on the oil yield and biomass production were evaluated. NPK (4.63ml/kg and 3.91ml/kg at 12 and 24 weeks respectively) application leads to higher oil yield than Urea (4.40ml/kg and 4.09ml/kg at 12 and 24 weeks respectively, while. NPK (2.49kg/6.48m2, 8.36kg/6.48m2 at 12 and 24 weeks respectively) application gave a higher biomass than Urea (1.91kg/6.48m2, 5.68kg/6.48m2 at 12 and 24 weeks respectively).
