PSB isolates in rhizosphere soil

Phosphate is the key macronutrient required for the growth of plants. The soluble forms of phosphorus when applied to soil are rendered insoluble by undergoing chemical fixation. The soil collected from organic farm, SKUAST- Jammu was investigated for screening the phosphate solubilizing bacteria. In the present study, soil samples were collected from rice rhizosphere of sixteen varieties grown in OFRC, SKUAST- Jammu. This study revealed the existence of Phosphate Solublizing bacteria in the rhizosphere soils of rice.

Microbial biodiversity in the soil plays a significant role in metabolism of complex molecules and help in plant nutrition. Phosphate solubilizing Bacteria (PSB) increases availability of phosphorus, therefore reducing the application of chemical fertilizers. The present study was aimed to isolate and characterize the selected phosphorus solubilizing bacteria from Rhizospheric regions of Walnut (Juglans regia).

Phosphorous is one of the important macronutrient along with nitrogen which limit the growth, development, and yield of the plant. The soluble forms of phosphorus when applied to soil become insoluble through chemical fixation. The Phosphate solublizing bacteria (PSB) plays a very vital role in making soluble phosphorous available to the plants. A study was undertaken in rice growing area of Jammu district, J&K, to screen the phosphate solubilizing microorganisms from the rhizosphere soil. The soil samples were collected from two rice growing blocks, R. S.

The use of phosphate solubilizing bacteria (PSB) as biofertilizers has concurrently increased phosphate uptake in plants and improved crop yield in several crops. A laboratory study was conducted to isolate, identify, and characterize the phosphate solubilizing bacteria from different crop soils. The population of PSB was higher in the rhizosphere soil of maize. Preliminary selections as PSB were done on the basis of formation of transparent zone around the colony on Pikovaskaya’s agar medium. The isolated PSB were identified by their morphological and biochemical properties.

Rice crop harbours diverse beneficial plant growth promoting diazotrophs which mostly plays a significant role in supplementing not only N fertilizer but also gives indirect benefit to the crops by improving their productivity and immunity. Considering all the benefits from PGP diazotrophs, rice rhizospheric soil samples were collected randomly from 20 different locations of Jorhat district, Assam. Altogether, 53 rhizobacterial cultures were isolated in non-selective TSA media.
