Phosphate solubilising inoculants on (Jumpstart) growth parameters of rice (Oryza sativa L.)

Author(s): M Geethalakshmi and Dr. P Sangameshwari

Abstract: Phosphorus (P) plays an important role in several physiological and biochemical activities in plants. P in soils is incapacitate due to formation of impenetrable complexes such as iron and aluminium hydrous oxides and calcium carbonate. Phosphate-solubilizing microorganisms (PSM) play a contributor in insoluble phosphates into soluble forms involves processes of acidulation, ion chelation and exchange reactions. In this experiment was carried out to study the Growth parameters of phosphate solubilising inoculants (JumpStart) on rice variety CO 47 in rice crop. The present study revealed that the treatment P3S3 (100% P + JumpStart 10E5) was recorded increased Seedling Growth will be increase in P3S3 treatment. The Plant Height will be increased at grain filling (111.67 cm), Root/Shoot ratio (0.494 mg g-1) and Root Volume will be increased at Active tillering and 50% flowering stage. The uptake of P by plants was found higher in P3S3 treatment observed at all stages of crop growth. At 50% flowering stage, phosphorus (69.26 kg ha-1), uptake were observed higher in P3S3 treatment than control. This might be due to the significant increment of major Growth Parameters such as Root and Shoot ratio by the application of 100% recommended P with seed treatment of 10E5 JumpStart.
