In the present study collected twenty (20) direct sown paddy rhizosphere soil samples from four districts of Andhra Pradesh and recorded their geographical position of collected soil samples. From that thirty two (32) Zinc Solubilizing Bacteria (ZnSB) isolated by using zinc phosphate [Zn3(PO4)2] as a insoluble source of zinc in the trismineral salts media. Zinc solubilizing isolates coded based on their soil sample collected geographical position, recorded the morphological, cultural characteristics of ZnSB.

Fluorescent Pseudomonas species are the diverse group of soil microorganisms that are involved in plant growth enhancement through various direct or indirect mechanisms. The present study was conducted to investigate the phytohormone production and other plant growth promoting traits of indigenous fluorescent Pseudomonas sp. isolated from apple rhizosphere.

Three species of Aspergillus (A. niger, A. flavus, A. terreus) were found to be effective in phosphorous solubilization in order to utilize these species for large scale production of bioformulation, the basic studies on effect of various carbon and nitrogen sources on growth and sporulation was done. Richard’s broth was used as basal medium to study the influence of various carbon and nitrogen sources.

Phosphorous is one of the most abundant metallic element found in the earth’s crust and present in soils in both organic and inorganic forms. Though it is present in high concentration, only 0.1% of the total P is available to plant because of poor solubility and its fixation in soil with other metallic elements in the soil such as Ca, Al, Fe to form calcium phosphate, aluminum phosphate and ferrous phosphate and thus becomes unavailable to plants.

Use of nitrogen fixing and phosphate solubilizing microorganisms (biofertilizers) has become an important aspect of pulse crops production technology. The efficiency of these microorganisms differs widely in accruing the benefits of their application in crops. Ten Mesorhizobium isolates having various plant growth promoting (PGP) traits including phosphate solubilization were screened for their symbiotic efficiency in terms of root nodulation, plant dry matter production, nitrogen and phosphorus content and nitrogen fixation by chickpea plant in a field experiment during 2015-16.

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 role of Zn as micronutrient in healthy growth of plants is very important. The microorganisms present in phyllospheric environment have capability to increase micronutrient availability to plants. Total forty eight isolates were obtained from five different crops (wheat, mustard, cotton, pearl millet and moong). All isolates were characterized for different plant growth promoting attributes i.e., production of ammonia, IAA, and solubilization of Zinc, Phosphate. Among all isolates total 87.5 % showed IAA and Ammonia production in different range. Total 72.91 % Zn solubalization and 60.

Plants acquire phosphorus from soil solution as phosphate anion. It is the least mobile element in plant and soil contrary to other macronutrients. In the present study phosphate solubilizing bacteria were isolated from rhizosphere of four different crops on Pikovskaya’s agar medium. The potential isolate was selected on the basis of reduction in pH of media and formation of halo zone. Its biochemical study was conducted which conclude that the isolate belong to Bacillus sp.

Biological control of soilborne plant pathogens is a possible alternative to the use of chemical pesticides, which are harmful to the environment. Under greenhouse and field conditions several isolated strains of the fungus Trichoderma have been found to be effective biocontrol agents of various soilborne plant pathogenic fungi.
