Abstract


An experiment was conducted at the Department of Horticulture. University of Agricultural Sciences. Dharwad to study the effect of vesicular arbuscuiar mycorrhizae (VAM). types of cutting and intermittent mist on rooting and sprouting percentage and period taken for sprouting. Among three VAM fungi tried, maximum percentage of rooting (69.93%) and sprouting (42.43%) was observed in cuttings inoculated with Acaulospora laevis. Orthotropic cuttings showed higher rooting percentage on inoculation with VAM The period required for producing first sprout was less in cuttings inoculated with A laevis (21.5 days). The percentage root colonization and spore count were also maximum with the inoculation of A. laevis. Intermittent mist enhanced the rooting and sprouting of the cuttings. Both in misthouse and open condition. runner cuttings showed higher sprouting percentage and earlier sprouts. The present study clearly indicates that VAM fungi can be effectively utilised to get higher number of rooted and sprouted cuttings in pepper.
