This study was conducted to determine the interrelationships among plant properties, some quality properties and elements in lettuce grown by applying vermicompost in different proportions. The experiment was carried out in the non-heated plastic greenhouse in Karabük province during the autumn growing season in 2017 and Maritima variety was used in the study. In this study, 19 properties related to plant and quality and 21 elements were examined. The interrelationships among the examined properties were evaluated by correlation analysis. Minimum and maximum values, means, standard errors, standard deviations and variation coefficients belonging to the examined properties were determined. The plant height, plant wet weight, number of marketable leaves, chlorophyll content, nitrogen content, phosphorus content and potassium content in lettuce used different fertilizer applications ranged from 16.00 to 30.00 cm, 133.80 to 320.90 g, 18 to 36, 13.10 to 29.30 spad, 4.29 to 6.98%, 2211 to 3711 mg kg-1 and 17129 to 25354 mg kg-1, respectively. In the study, it was determined that vermicompost applications have positive effects on plant growth, quality and plant nutrient content in lettuce. As a result of the correlation analysis, significant and quite high positive relationships were determined between leaf length and leaf width (r = 0.827 **), and between dry matter content and water soluble dry matter amount (r = 0.802 *). The significant and positive correlations were also found between plant wet weight which is the most important yield parameter and plant dry weight, leaf length, plant height and leaf width. When the relationships among the elements were examined, the highest positive significant correlation was detected between iron and chromium (r=0.822 **). In addition, significant and quite high positive correlations were determined between iron and manganese, calcium and aluminum; between sodium and magnesium and potassium; between nickel and aluminum; between manganese and calcium. As a result, it can be said that analysis results should be taken into consideration for the selections in lettuce breeding programs.
