Studies were carried out to evaluate mass multiplication, shelf-life and Plant growth promoting characteristic with the formulation of Pseudomonas sp. stored at 25±20C over a storage period of seven days in a natural source (Coconut water). Coconut fruit a natural formulation was made and found that the population of Pseudomonas sp. was increased significantly, maximum population of Pseudomonas sp. was recorded when 3 ml suspension of Pseudomonas sp. was injected into intact coconut fruit (2.98 x 1010 cfu/ml). In shelf-life study, the population of Pseudomonas sp. was increase on first day (2.22 x 1010 cfu/ml) of inoculation and reached it's highest. Then after, it was observed to decrease upto 7th days (2.2 x 108 cfu/ml). Thus the prepared natural formulation can be stored for 7 days. The proposed protocol of coconut water formulation suggested is absolutely cost effective and easy to prepared at small scale level. In PGPR activity of finger millet, maximum germination (93.67 %), root (8.60 cm) and shoot (5.50 cm) length and root bacterization (5.33 x 104 cfu/g) was recorded in intact coconut water formulation Pseudomonas sp. There was significantly lower leaf blast intensity was recorded in coconut water intact formulation of Pseudomonas sp. (6.79 PDI).
