Enhanced Agroproductivity by Phosphate Solubilising Bacteria

The demand in agricultural field can be fulfilled by providing supplements in the form of biofertilizers and biopesticides. Biofertilizers are a consortium of microorganisms that helps for the growth of plants by providing necessary nutrients either by fixing atmospheric nitrogen or by solubilising the phosphorous present in the soil. In this present study, Bacillus coagulans acts as phosphate solubiliser in degrading rock phosphate by providing suitable carrier material. Bacillus coagulans was grown in Nutrient Medium and bioprocess conditions for maximum growth of the organism was optimized. It was found that Bacillus coagulans showed maximum cell concentration at pH 7.5, temperature 37°C and incubation period of 24 hrs. The culture is then mixed with suitable powder and liquid carriers. Powder carrier such as water hyacinth and groundnut shell are mixed with bio inoculum. Liquid carriers such as herbal mixture solution, archaea bacterial solution and treated waste water are mixed with culture at equal proportion. Life span of the organism along with the carrier material was scrutinized for a period of 120 days. The field response of the formulated biofertilizer was checked by applying on shallots. Among the powder carriers, water hyacinth showed highest cell count of 74×109 cfu/ml. Comparitively, among the liquid carriers archaea bacterial solution showed highest cell count of 77×109 cfu/ml. In order to determine the efficiency, morphological characters of the shallots were examined..
