Abstract:

The present investigation entitled “Effect of IBA and NAA and their combination on rooting in stem cuttings of African Marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda” was conducted in the Horticultural Research cum Instructional Farm at Department of Floriculture and Landscape Architecture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalya, Raipur (C. G.), season 2017. The experiment consisted 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 which were treated for root initiation in stem cutting of marigold under Chhattisgarh plain region. The experiment was laid out in a Completely Randomized Design with three replications and the cuttings were planted on protray and placed in mist chamber.

The result revealed that growth regulators IBA and NAA had significantly effect on rooting and shooting performance of marigold. The maximum survival percentage (88.33%) of rooted cuttings were recorded under 200 ppm IBA and 300 ppm IBA at 35 days after planting of cuttings. While 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 and the number of roots (93.44), fresh weight (404 mg) and dry weight of root (34.11 mg) were recorded maximum under 300 ppm IBA whereas, average length of roots (12.23 cm) were observed maximum under IBA 100 ppm.
