An investigation was carried out to see the effect of GA3 and growing media on seed germination, survivability and physiological parameters of Custard apple (Annona squamosa L.) from December 2014 to April 2015 at Fruit Research Station, Imalia Farm, Department of Horticulture, College of Agriculture, JNKVV, Jabalpur (M.P.) Amongst different growing media, percent of germination, survivability percentage, Leaf Area Index (LAI), Leaf Area Duration (LAD), Light transmission ratio (LTR), Energy Interception (Ei), Seedling vigour index I (cm) and Seedling vigour index II (g) were found significantly superior under M5 growing media comprising soil + vermicompost + AZO + PSB followed by M2 (soil + vermicompost), M4 (soil + FYM + AZO + PSB), M1 (soil + FYM), M3 (soil + AZO + PSB) and M0 (only soil). Survival of seedling and germination percentage was highest in media M5 which was at par with M4. As regards the interactions, germination percentage, survivability, Seedling vigour index I (cm) and Seedling vigour index II (g) were found not significant. However, G2M5 treatment combination [seed soaked in 400 ppm GA and sown in soil + vermicompost + AZO + PSB] recorded superior and G0M0 combination (control) was found inferior in respect to survival and most of growth parameters. In some physiological parameters like Leaf Area Index (LAI), Leaf Area Duration (LAD), Light transmission ratio (LTR) and Energy Interception (Ei), interaction was found significant. In respect to germination, G3M5 treatment combination [Seeds soaked in 600 ppm GA concentration and sown in soil + vermicompost + AZO + PSB] showed superiority over rest of the treatment combinations whereas minimum was observed in control (G0M0).
