摘　　要：Pot experiments were conducted in a glasshouse to determine the growth pattern of lettuce, true potato seedlings （TPS） and single node cuttings of TPS in response to biochar. The treatments were arranged in a randomized complete block design with 5 treatments （0, 10, 30, 50 and 100 t ha^-1） ofbiochar from greenwaste with 5 replications in lettuce, 10 in TPS and 5 in single node cuttings of TPS. The observations recorded on growth parameters showed that biochar had significant effect on growth of lettuce but no consistent effect on growth of TPS and single node cuttings. Among the biochar rates, 30 t ha^-1 had the greatest influence on overall growth of lettuce. The pH and electrical conductivity increased as the biochar rates increased in all experiments. These results provide an avenue for soil management system by using biochar as an amendment in horticultural crops. However, their verification in the field is important for specific recommendations.Pot experiments were conducted in a glasshouse to determine the growth pattern of lettuce, true potato seedlings （TPS） and single node cuttings of TPS in response to biochar.
