Response of Phosphate Solubilizing Microorganism on Quality of Wheat(Triticum Aestivum L.) Plant Grown Conventionally in Temperate Climate

Shruti Agrawal and RK Pathak

The present study was conducted to assess the effect of inoculation on wheat (Triticum Aestivum L.) with the bacterium Pseudomonas fluorescens sp. SSC in Doon valley by conventional method. Treatments involved SSC inoculation with phosphorus fertilization. The results revealed that application of phosphate solubilising bacteria in combination with half dose (50%) of superphosphate significantly increases the yield (36%) as well as P status in soil and plant over control. It significantly increases the total uptake of P content in plant by 33%. The conventional treatment without bacterial inoculation has resulted in very low P uptake in plants. Thus, it is suggested that application of phosphate solubilizer SSC is able to mobilize more P to the plants and improves plant yield. Thus, results of the study indicate that inoculation of wheat with P. fluorescens SSC alone improves yield and quality parameters allowing input of reduced dosage of phosphorus fertilizer.
