Effect of IBA and NAA and their combination on the shooting of stem cuttings of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda

Abstract

The experiment was carried out in completely randomized design with three replications and the cuttings were planted on protray and placed at mist chamber and consist of three different concentrations of IBA (100, 200 and 300 ppm), NAA (100, 200 and 300ppm) and IBA+NAA (100+100, 200+200 and 300+300 ppm) along with control were treated for shooting in stem cuttings of marigold under Chhattisgarh plain region. The result revealed that growth regulators IBA and NAA had significantly effect on shooting performance of African marigold. The number of sprouts per cutting (7.55), average length of shoot (8.00 cm), number of leaves per cutting (163.44), fresh weight (1140.55 mg) and dry weight of shoot (159.00 mg) were recorded maximum in NAA 200 ppm at 35 days after planting of cuttings.
