In this study, the effects of Gytjja on some yield criteria of lettuce (Lactuca sativa) grown in Ni contaminated two different soils (Inceptisol and Entisol) were investigated. This study was conducted with the application of three levels of gytjja (0, 5 and 10%) in two different soils (Inceptisol and Entisol) contaminated with three levels of Ni (0, 40 and 80 mg kg(-1)) in a factorial experimental design with three replications. As a basic fertilization, 300 mg kg(-1) N and 90 mg kg(-1) P2O5 were applied into each pot. At the end of the study, the highest value for plant length (20.50 cm), leaf number (16.3) and plant fresh weight (10.67 g) were obtained in the 10% gytjja without Ni application in Inceptisol soil. The plant growth parameters were higher in the Inceptisol soil than in the Entisol soil. According to the results, gytjja doses had the positive effects on plant growth criteria of lettuce in Ni contaminated soils. Ni applications decreased the mean values of plant growth criteria.
