Response of marigold cuttings to IBA and media for rooting and growth performance

An experiment was conducted to study the response of IBA and rooting media on rooting of cutting in African marigold cv. African Double Orange during the kharif season 2017-18 at Horticulture Section, College of Agriculture, Nagpur. The experiment was laid out in Factorial Completely Randomized Design with main factors viz.,50 ppm IBA, 100 ppm IBA, 150 ppm IBA and control and sub-factors, Sand 100%,Cocopeat + Perlite (3:1), Sand + FYM (1:1), Soil + FYM (2:1). Results of the investigation revealed that among different concentrations, IBA 100 ppm recorded significantly early sprouting of cuttings, maximum number of leaves, fresh and dry weight of shoot, final success percentage of rooted cuttings, length of roots and number of roots. Similarly, rooting media- Soil: FYM (2:1) found to be superior in respect of shoot and root parameters in rooted cuttings. However, minimum days to rooting of cuttings were observed in the treatment combination IBA 50 ppm with rooting media cocopeat: perlite (3:1).
