      abstract = {The response of thyme (Thymus vulgaris L.) lo sources of  nitrogen (N) fertilizer application was studied in field  experiments conducted in 1992 and 1993. Thyme plants were  grown in plots consisting of 3 rows 2.1 m long with 40 cm  between rows. In 1992, thyme plants were fertilized with N  at a rate of 115 kg. ha4 using N-source treatments of  ammonium nitrate (35% N), ammonium sulfate (21% N), and  urea (45% N). One treatment was applied with cow manure (2%  N) at a rate of 230 kg N. ha '. A control plot (no N) was  included as a treatment. In 1993, the same N fertilizer  sources were used but N was applied at a rate of 100 kg.  ha"' for inorganic fertilizers and 200 kg. ha"' for organic  (cow manure) fertilizer. In both experiments phosphorus (P)  and potassium (K) were applied at a rate similar to the P  and K content of cow manure equivalent to 50 and 190 kg. ha  in 1992 and 44 and 166 kg.ha"' in 1993, respectively. In  1992, results indicated no significant differences in plant  height, plant fresh yield and total dry matter yield among  nitrogen fertilizer sources and the control. Results  obtained in 1993 showed that urea and cow manure were  superior to ammonium nilrate and the control in terms of  total plant fresh yield. Plants fertilized with urea and  cow manure produced total fresh yields of 7.5 and 7.2 t. ha  ', respectively. Lowest plant fresh yield of 5.1 t ha ' was  obtained from plots applied with ammonium nitrate. No  significant differences in plant height were observed  between treatments. It appears that urea and cow manure are  the best sources of N fertilizer for thyme production in  the Virgin Islands.},
