Abstract:

Soils contain substantial reserves of total phosphorus but majority is present in the form of insoluble phosphates and hence cannot be utilized by the plants. To overcome this P deficiency in soils, P fertilizers are applied. However, after application, a considerable amount of P is rapidly transformed into less available forms by forming a complex with Al or Fe in acid soils or Ca in calcareous soils before plant roots had a chance to absorb it. Thus the fixation and precipitation of P cause P deficiency, and in turn, restrict the growth of crops severely. Phosphate solubilizing bacteria (PSB) are ubiquitous in soils and capable of hydrolyzing organic and inorganic phosphorus from insoluble compounds and converting to the soluble forms. Use of PSB as inoculants increases P uptake by plants and thus play a role in plant phosphorus nutrition by enhancing its availability to plants and improving their growth and yield. In the present study, tomato plants were inoculated with culture isolate Bacillus PSB 24 and various morphological growth characters were analyzed at different time intervals. The culture inoculum of Bacillus PSB24 caused an increase in growth parameters over control and showed better growth in shoot as well as root and an enhancement in both root and shoot dry and fresh weight in tomato plants.


Keywords: Phosphate solubilising bacteria, PSB inoculants, morphological growth parameters, fresh weight, dry weight.
