Phosphate Soluble Bacteria, Growth, Mustard


Phosphate solubilizing bacteria enhanced the plant performance and benefits the plant by various mechanisms. Phosphate solubilizing bacteria is environmental friendly bio fertilizer. In present study influence of Phosphate Solubilizing Bacteria was investigated on growth of Brassica compestris under drought stress. Drought was given at three different stages, with and without Phosphate Solubilizing Bacteria. The PSB was applied to seeds surfaces before sowing in the pots. Drought duration remained for 14 to 21 days. Mean data reveals that drought stress inhibited Plant growth; shoot length, leaves number, number of branches per plant, Length & width of leaf. PSB inoculation increased the growth parameters i.e. the plant height, root & shoot length, number of leaves and branches. Drought duration also has the adverse effects on the growth of the plants. PSB inoculation effectively increased the plant growth under the drought stress. Under drought stress, plant growth was inhibited as compare to those having PSB inoculation at drought stages which clearly reflects that the PSB has improved the yield and other enhanced other parameters of the plants so it is concluded that PSB should be applied to the seed for better production of brassica.
