Phosphate Solubilizing

Nine isolates of Trichoderma spp. were investigated for their ability to solubilize insoluble phosphate in Pikovskaya's broth and were compared with an efficient phosphate-solubilizing bacterium Bacillus megaterium subsp. phospaticum PB that was used as the reference strain. All 9 Trichoderma isolates were found to solubilize insoluble tricalcium phosphate to various extents. Trichoderma viride (TV 97) (9.03 µg·mL–1), Trichoderma virens (PDBCTVs 12) (9.0 µg·mL–1), and Trichoderma virens (PDBCTVs 13) (8.83 µg·mL–1) solubilized 70% of that solubilzed by the reference strain Bacillus megaterium (12.43 µg·mL–1). Pot culture and field evaluations with Trichoderma harzianum (PDBCTH 10), Trichoderma viride (TV 97), and Trichoderma virens (PDBCTVs 12) using chickpea (Cicer arietinum L.) 'Annegeri-1' as the test plant and rock phosphate as the phosphorus source showed significantly increased P uptake in plants treated with Trichoderma harzianum (PDBCTH 10) followed by Trichoderma virens (PDBCTVs 12) and Trichoderma viride (TV 97). Inoculation of Trichoderma spp. also showed increased growth and yield parameters of chickpea compared with the uninoculated controls under both glasshouse and field conditions.Key words: Cicer arietinum, nutrient uptake, phosphate solubilization, plant yield, Trichoderma spp.

The Impact

Objective: The inoculants, mainly nitrogen fixers and phosphate solubilizing microbes, have an influence on plant growth attributes. The current study was conducted to assess the fertilizing activity of A. chroocaccum and B. megaterium strains on growth, yield parameters and nutrient uptake of Sorghum bicolor. Methods: The isolation and identification of the nitrogen-fixing bacterium- A. chroocaccum and phosphate solubilizing microbe- B. megaterium and the growth and yield parameters of Sorghum bicolor as well as NPK uptake levels were studied. Results: A. chroocaccum and B. megaterium exhibited the proliferation of microbial population in soil by synergistic interaction with plants, and the application increased the availability of NPK in the soil after harvest of the crop. These beneficial inoculants are also known to help in the uptake of some other nutrients. The maximum beneficial aspects of the plant were noticed in the plants inoculated with 100% Recommended Dose of Fertilizer (RDF)+ A. chroocaccum+ B. megaterium, and the least was noticed in the control plants at all growth stages and at the time of harvest. Conclusion: From this study, it can be concluded that the beneficial effect of A. chroocaccum and B. megaterium is observed in sorghum crop with improved yield and nutrient uptake. Therefore, this species can be used extensively for future inoculation of the sorghum crop for better growth and development and for good returns in an ecological way.
