The experiment was carried out in the Horticulture Department and Landscaping, College of Agriculture, Tikrit University, during the Agricultural season 2021-2022 to study the response of Chinese carnation to biochar and growth regular carried out with two factors Add biochar at two levels without adding and adding 10 g under the seedlings, the second factor was spraying with gibberellin and cytokinin growth regulators at four levels (no spray, spraying-1 with gibberellin at a concentration of 100 mg L-1 Cytokine spray at a concentration of 100 mg. Liter-1 and spraying with a mixture of gibberellin and cytokine). The experiment was in a randomized complete block design RCBD, and three replicates, results show that superiority of the treatment of adding charcoal and it gave the highest plant height of 77.26 cm and the highest branches numbers and dry weight 25.24 branches plant-1 and 76.15 g, Spraying with a mixture of gibberellins and cytokinin superior in the rest studied traits which were dry weight 16.02 g and NPK 1.60%, 0.26% and 1.75%, and flowers numbers 49.38 plant flowers-1, and flower diameter 3.36 cm.
