This study was carried out to determine the effect of poultry manure compost and zeolite (clinoptilolite) on soil properties and yield, morphologic, agronomic and quality properties of lemon balm (Melissa officinalis L.) under the greenhouse conditions.In this research, increasing ratio of composted poultry manure (50, 100, 150, 200 g pot-1) and zeolite (50, 100 g pot-1) have been applied to soil sample with different combinations and the study was conducted randomized plots design with 3 replications in the plastic greenhouse which was located Applied Research Centre for Agriculture of Uludag University.At the end of the research, plant height (cm), canopy width (cm), green herb yield (g plant-1), drog herb yield (g plant-1), drog leaf yield (g plant-1), total nitrogen (N), phosphorus (P) and macro plant nutrients like sodium (Na+), potassium (K+) and calcium (Ca+2), magnesium (Mg+2), micronutrients like iron (Fe+2), zinc (Zn+2), copper (Cu+2), manganese(Mn+2), the ratio of essential oil (%) and the essential oil yield (ml bitki-1) in leaf and the components of essential oil of lemon balm were determined and results are compared statistically.As a result of research the highest values obtained from CMP4 + Z2 + ½ N (liquid) and CMP4 + Z2 + ½ N (urea) treatment, compared with control. The main components of the essential oil of lemon balm (Melissa officinalis L.), geraniol, geranial, citronellal, neral, ß-pinen and linanool were determined.Also, pH, EC, organic matter, total nitrogen, available phosphorus, macro and micro plant nutrients of the experiment soil at the end of the harvest were determined and the results were compared statistically.According to the results that have been obtained from the soil after harvest when the dose rates were increased, the pH value decreased and EC value increased. Also, the total nitrogen, the available phosphorous, the macro and micro plant nutrients were increased.
