Abstract :Forage kochia, a subshrub forage plant, grows naturally in the pastures of dry areas in Turkey. Their seeds grow slowly in nature, and being short duration of seed viability could be caused by limitations on the cultivation of forage kochia in Turkey. Forage kochia seedlings can be produced serially quickly with cutting propagation as vegetation propagation method. Therefore, forage kochia cuttings were exposed to 12 different IBA concentrations (250, 500, 1000, 1500, 2000, 2500, 3000, 4000, 5000, 6000, 10000, and 15000 mg kg-1) at four holding times (5, 30, 180, and 900 s) in this research carried out Completely Randomized Design in the greenhouse. We investigated the percentage of rooting, the number of the root, shoot and root length, shoot and root weight, dry root weight, and leave yellowing of these cutting. The best developments in the percentage of rooting (100%), number of roots (> 7), shoot length (> 20 cm), root length (>10 cm), root weight (>0.60 g), dry root weight (>0.1 g) and leave yellowing (score >1.60) were obtained from 500 mg kg-1 IBA at 900 s, 5000 mg kg-1 IBA at 180 s, and 10000 mg kg-1 IBA at 5 s interactions. As a result, we advised 500 mg kg-1 IBA at 900 s, 5000 mg kg-1 IBA at 180 s and 10000 mg kg-1 IBA at 5 s for the quick and economically cutting propagation of forage kochia.
