Influence of rooting hormone and rooting substrate on growth of apical shoot cuttings of mulberry (Morus indica l.) Using mini clonal technology at nursery level

An experiment was conducted at Department of Sericulture, Forest College and Research Institute, Mettupalayam to analyse the effect of rooting hormone and their concentrations, rooting medium on apical shoot cuttings of mulberry. Auxin with various concentrations namely IBA and NAA (1000, 2000, 3000, 4000 and 5000 ppm) and rooting mediums such as Soil, Soil: Sand: FYM (1:1:1), Soil: Coir pith (1:1), Soil: Sand: Vermicompost (1:1:1) and Soil: Coir pith: FYM (1:1:1) were used for this study. Mulberry apical cuttings were treated with different hormonal concentrations and placed in different rooting medium under shade house condition. After planting survival per cent, sprouting per cent, rooting per cent and shoot length of the plants were examined. Among the various interaction effect, IBA at 3000 ppm treated plants placed in Soil: Coir pith: FYM medium performed well in all parameters.
