Abstract:
An experiment to assess two plant growth regulators IBA and NAA at three different concentrations 1000 ppm, 1500 ppm and 2000 ppm treated in combination with two concentrations of coconut water 50 ml and 100 ml and control (treated alone with coconut water) on semi hardwood cuttings of Bougainvillea (Bougainvillea spectabilis L) was conducted at College of Horticulture, Mojerla during 2017-18. The experiment was laid out in Factorial Completely Randomized Design with three replications. Cuttings were obtained from healthy, vigorous growing shrubs which were 15-20 cm long and 2-3 nodes. Leaves were removed from the cuttings and were treated with IBA and NAA in combination with coconut water, then planted in plastic bags filled with mixture of Red soil, sand and Compost with the ratio of 1:2:1. Data were collected on survival percentage and economics. The results showed that the treatment of cuttings with IBA 2000 ppm was significantly better than the control and all the other treatments with respect to survival percentage and economics (B:C ratio).
