Effect of IBA and types of cuttings on rooting of Ixora

Abstract

The study was conducted to find out "Effect of Indole butyric acid (IBA) on cutting on rooting of Ixora" at farm of Horticulture Section, College of Agriculture, Nagpur in 2019-2020. The experiment was laid out in Factorial Completely Randomized Design with fifteen treatments and three replications. The treatments comprised three types of cuttings i.e. Softwood cuttings, Semi hardwood cuttings and Hardwood cuttings and five concentrations of IBA, 0 ppm, 1000 ppm, 2000 ppm, 3000 ppm, 4000 ppm. The result obtained from the present investigation in respect of root parameters, it was observed that, minimum days to rooting was observed in treatment T13 (hardwood cuttings treated with IBA 2000 ppm). However, maximum number of roots cutting-1 , length of main root, survival percentage of rooted cuttings, root volume, fresh weight of roots cutting-1 and dry weight of roots cutting-1 was noticed in hardwood cuttings with 2000 ppm IBA.
