Abstract:
In the present study, attempts were made to Analyze the effect of 3 Phosphate solubilizing bacteria (PSB) recovered from forest ecosystem of Pantnagar, India on wheat plant vigor. For this, a pot trial in a Completely Randomized Design (CRD) with a superior wheat genotype (CBW 38) was carried out in glass house conditions. The response was measured in terms of two soil enzyme activities e.g. fluorescein di acetate (FDA) hydrolysis and alkaline phosphatase (AP). Plant health was measured in form of plant vigor parameters (shoot length, root length, shoot fresh weight, root fresh weight and grain yield). All three PSB strains showed positive for phosphorous and zinc solubilization activity as well as FDA and AP enzyme activities. During pot trial it was also observed that PSB strains promoted development of wheat plant thereby enhancing the crop yield. Among the three PSB strain, Pseudomonas putida-P3 was found to be most effective and show maximum phosphate (3.4 cm); zinc (3.0 cm) and inorganic phosphate (72.48 µgmL-1) solubilisation index with a drop of pH to 4.6 along with maximum FDA (78.6) and AP (62.6) µgmL-1h-1 activity. All these parameters lead to increase in crop yield from. 24 Kgha-1(under uninoculated conditions) to 2.4 Kgha-1 in P3 inoculated crop. Therefore Pseudomonas putida-P3 could be developed as potential bioinoculant.
