Abstract
Bacteria were isolated and characterized from the root nodules of Akashmoni (Acacia nilotica) to study their effects on growth parameters, nodulation and N uptake by sapling of Akashmoni. Five isolates were obtained from Akashmoni and were identified them as Bradyrhizobium on the basis of their colony, morphological and biochemical characteristics. A pot experiments were conducted by using 6 treatments, comprising 5 isolates of Bradyrhizobium and an uninoculated control to evaluate the performance of the isolates. The experiment was laid out in a Completely Randomized Design (CRD) with 3 replications. Statistically higher values for all the parameters were obtained from Bradyrhizobium inoculation over uninoculated control (T1) except leaf number plant-1 at 30 DAS. The highest value of plant height (cm plant-1) and leaf number plant-1 at 60 DAS were recorded as 30.33 cm plant-1 and 12.67 plant-1, respectively due to the treatment T3 (AN-R-2). The highest nodule numbers plant-1 and dry weight of nodule (mg plant-1) were also noted as 134.7 plant-1 and 76.6 mg plant-1 for the same treatment. The highest root, shoot and total dry matter yields of Akashmoni were also found for the same treatment T3 (AN-R-2). The total dry matter yield of Akashmoni was increased by 149, 198, 144, 55 and 82 % over control due to T2 (AN-R-1), T3 (AN-R-2), T4 (AN-R-3), T5 (AN-R-4) and T6 (AN-R-5), respectively. The total N in shoot showed a similar pattern and corresponding increase in N uptake by shoots were 191, 396, 285, 80 and 242 %, respectively. Considering all the parameters the isolate T3 (AN-R-2) showed the best performance.
