Abstract:

The green revolution bought amazing consequences in food grain production but with insufficient concern for agriculture sustainability. Biofertilizers are gaining importance in sustaining agriculture. Various complementing combinations of microbial inoculants for management of major nutrients are necessary for agriculture sustainability. The present investigation was conducted to optimize the effect of hydrogel for their ability to support growth, shelf life stability and bio-efficacy of hydrogel based bioinoculants (Azotobacter chroococcum, Pseudomonas fluorescence and Trichoderma viride). Hydrogel products constitute a group of polymeric materials, the hydrophilic structure of which renders them capable of holding large amounts of water in their three-dimensional networks. Extensive employment of these products in a number of industrial and environmental areas of application is considered to be of prime importance. Shelf life studies of bio-inoculants formulations with three different carriers viz: lignite, liquid and hydrogel shelf after 90 days incubation at room temperature, exhibited population of nitrogen fixer Azotobacter chroococcum 1.2×107, 1.4×108 and 3.5×109 CFU mL-1, phosphate solubilizer Pseudomonas fluorescence 2.2×107, 2.4×108 and 4.5×109 CFU mL-1 and phyto-stimulator Trichoderma viride 1.4×106, 2.8×107 and 2.5×108 CFU mL-1 respectively. Wheat seeds treated with hydrogel based bioinoculants and the consortium enhanced plant growth positively by a multiplicity of synergistic mechanism compared to liquid and lignite based microbial consortia.
