This research was done to find out the effect of increasing vermicompost application on yield of lettuce (Lactuca sativa L. var. crispa) plant. For this purpose Lactuca sativa L. var. crispa cv. Bellafiesta lettuce kind and Riverm Company vermicompost were used in this research. Four vermicompost doses (0 kg/ha, 4000 kg/ha, 8000 kg/ha and 12000 kg/ha) were applied to lettuce plant. According to the results, important increases of fresh weight, plant size, number of leaf, length and width of leaf for each plant and dry matter yield of plants were determined with increasing vermicompost applications. But the effects of Vermicopmost applications on some macro element (N, P, K, Ca and Mg) contents of plant were not found significant statistically.
