Effect of bioinoculants on growth parameters of black pepper (Piper nigrum L.) at nursery stage

An experiment was conducted to study the effect of bioinoculants on growth parameters of black pepper at nursery stage at College of Horticulture, Sirsi from 2013 to 2015. The data recorded for three years clearly indicated that black pepper cuttings responded well to the inoculation with various microbial inoculants under nursery stage. The plant parameters viz., root length, root dry weight and number of leaves were found to be significantly highest in cuttings inoculated with T₅, T₆ and T₇ as compared to rest of the treatment combinations and uninoculated control. A matching trend was recorded with respect to beneficial rhizosphere microflora, per cent root colonization, spore counts and shoot P concentrations in black pepper cuttings.
