Abstract: An investigation was carried out to see the effect of GA3 and growing media on seed germination and growth of Custard apple (Annona squamosa L.)†at Fruit Research Station, Imalia Farm, Department of Horticulture, College of Agriculture, JNKVV, Jabalpur (M.P.) Amongst different growing media, all germination parameters like days taken to start germination, days taken to 50% germination, percent of germination in each treatment at 60 DAS and almost growth parameters like height of shoots, number of leaves per seedling, height of seedling, root length, number of roots/seedling, fresh weight of shoots, dry weight of shoots, fresh weight of roots, dry weight of roots 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), M0 (only soil) at 60, 90, 120 and 150 days after sowing, respectively. But mean value of girth of stem was observed slightly better in the treatments having FYM and bio-fertilizers (M4) closely followed by M1 (soil + FYM) and M5 (Soil + Vermicompost + Azotobacter + PSB. The concentration of 600 ppm (G3) was observed superior in germination point of view like days taken to start germination, days taken to 50% germination, percent of germination in each treatment and found statistically at par with other concentration of GA3 except G0 (water soaked seed). As regards the interactions, all germination parameters and almost growth parameters like height of shoots, number of leaves per seedling, girth of stem, height of seedling, root length, number of roots/seedling, fresh weight of shoots, dry weight of shoots, fresh weight of roots, dry weight of roots 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. 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 with respect to germination whereas minimum was observed in control (G0M0).
