Effect of bioformulations of Phosphate Solubilizing Bacteria (PSB) on the Growth and Biochemical Characters of the Gossypium Hirsutum and Zea Mays

Biofertilizers offer a new technology to Indian agriculture holding a promise to balance many of the short comings of the conventional chemical based technology. They are usually prepared as carrier based inoculants containing effective microorganisms. The present study was aimed at to study the nursery performance of different formulations of PSB in maize and cotton plants. The selected PSB was mass multiplied in the laboratory and incorporated into the nursery soil through different carrier material such as coirpith, vermicompost, organic manure, lignite and vermiculite. The effect of bioinoculants on the growth and biochemical characters were studied from the control and treated seedling of Gossypium hirsutum and Zea mays. The significant difference was observed in the growth and biochemical characters in both Gossypium hirsutum and Zea mays. The effect was differed with reference to the nature of carrier materials used for the preparation of bioformulations. The results indicated that the bioformulation prepared by composted coirpith had superior in plant growth and development.
