Abstract

This study was conducted to determine the effects of type, concentration and method of application of nitrogen fertilizer on the growth and yield of the medicinal plant, oregano (Coleus amboinicus Lour.). Two types of N fertilizer were used: urea [CH4N2O, 46-0-0] and ammonium sulfate [(NH4)2SO4, 33-0-0]. Each type of N fertilizer was given at the following concentrations: 0, 0.7 and 1.4 g N per plant. For each corresponding type and level of N fertilizer, two methods of application were used: direct incorporation of the powder/granule to the soil and dissolution of the fertilizer in water prior to soil application. The experiment was set-up in randomized complete block design with a total of 9 treatments, three replications, with 4 pots per treatment per replication. One oregano plant was established per plot. Oregano plants treated with N fertilizer were significantly taller, had more leaves and nodes, and had heavier fresh and dry weight of leaves and stems compared with the control plants. Urea and ammonium sulfate were equally effective in promoting the growth and yield of oregano. There was also no significant difference between the application of 0.7 and 1.4 g N per plant for either type of fertilizer. Furthermore, the response of oregano to the two methods N application was statistically similar. Within the limitation of the study, it can be concluded that N application regardless of type level and method of application was found to enhance growth and yield of oregano over the unfertilized plants.
