An experiment was carried out to assess the effect of potting media on seed germination and seedling growth for obtaining the vigorous rootstock for softwood grafting in jackfruit (Artocarpus heterophyllus Lam.). Healthy seeds of more than 3 g weight were thoroughly washed and treated with Carbendazim (50% WP @ 2 g L-1) for 5 minutes and sown in polybags having size 15 × 20 cm containing five different growing media viz., M1 - soil + FYM (3:1), M2 - soil + vermicompost + rice husk (2:1:1), M3 - soil + vermicompost + sawdust (2:1:1), M4 - soil + vermicompost + cocopeat (2:1:1) and M5 - soil + vermicompost + rice husk + cocopeat (1:1:1:1). The potting mixture containing soil, vermicompost, cocopeat and rice husk in 1:1:1:1 proportion was found to be best for obtaining the highest germination percentage (93.0 %), 11.88 days for initiation of germination, 22.88 days for 50% germination and 24.25 days for total germination. The inclusion of sawdust in media showed an inhibitory effect for all the aspects under study.
