Effect of nitrogen fertilization on essential oil yield and composition in different species and accessions of Lippia
Some species of Lippia genus have acquired importance due to its potential to yield essential oils with multiple uses and therefore requires research aspects related to the crop managing. In experiments conducted at the Experimental Center of Universidad Nacional de Colombia, Palmira (CEUNP), the effect of two sources of Nitrogen fertilization (hen manure and urea (50 and 100 kg of N/ha), two accesions of Lippia alba (Cítrica and Típica) and three of Lippia origanoides (Patía, Típica and Cítrica) were evaluated. A randomized complete block experimental design with five treatments and three repetitions was used. Yield of fresh and dried biomass, water vapor extraction of the essential oils was assessed and chemical composition of essential oils were made. The highest dry matter yield and essential oils obtained (3.382 kg/ha. and 82,9 l/ha respectively) were for L. origanoides accessions. The highest essential oil concentration (4,0 ml/100g) was obtained from L. origanoides Patía treated with 100 kg of N (urea)/ha. There was not significant differences (p
