RESPONSE OF JAMUN (SYZYGIUM CUMINI SKEELS.) TO GLOMUS FASCICULATUM AND BIOFORMULATIONS FOR GERMINATION, GRAFT TAKE AND GRAFT SURVIVAL

An investigation was carried out at the Horticulture Research Station, Bijapur (Tidagundi) to know the combined influence of Glomus fasciculatum and bioformulations on germination, graft take and graft survival of jamun. The experiment consisting of 10 treatment combinations with two main plots (M_1- with Glomus fasciculatum, M_2- Uninoculated) and five subplots (S_1- Amrit pani, S_2- Microbial consortia, S_3- Panchagavya, S_4- Inorganic fertilizer (60:30:90 g N:P:K per plant per year), S_5- Control) was laid out in split plot design with three replications. The non-descriptive uniform size jamun seeds obtained from a single tree in the farmer field of Soundatti were sown in polybags of 8×12 cm size containing a potting mixture of soil, sand and FYM in the ratio of 2:1:2. AM fungi inoculation was done by spreading 5 g of inoculum uniformly at 5 cm depth after putting a thin layer of soil on the inoculum. Jamun seeds were placed and covered with soil (2-3 cm). The polybags of respective treatments were labeled and kept apart enough from each other to avoid AM fungal cross contamination. The bioformulations were applied as soil application at 3% at monthly interval and watered daily. The results indicated that seeds inoculated with Glomus fasciculatum recorded the highest germination (83.60%), graft take (46.56%) and graft survival (89.10%) as compared to uninoculated seeds wherein germination was 76.40%, graft take 44.17% and graft survival 82.5%. Among different bioformulations, seeds inoculated with microbial consortia registered the highest germination (88.00%) graft take (49.68%) and graft survival (90.94%) as compared to uninoculated control wherein seed germination was 76.00%, graft success 41.42% and graft survival 77.05%
