Abstract
Mulberry (Morus indica) is the sole food crop to silkworm (Bombyx mori). The growth and development of mulberry indirectly influences the growth and development of silkworms. Considering this factor, the research study is carried out to recognize the effect of growth promoting bacterial endophytes on the growth parameters of mulberry. The isolated and identified promising isolates were applied to mulberry under nursery, to evaluate their impact in plants under in-vivo conditions. Out of isolated 30 isolates, 4 isolates attained as promising isolates through growth promotion tests and they were applied to mulberry cuttings in 15 different combinations. Through nursery studies, two isolates showed sound effect by promoting the growth of plants. These two isolates obtained from V1 and G4 varieties of mulberry and identified as Enterobacter cloacae using 16srRNA sequencing method.
