The Effect of Plant Growth Promoting Rhizobacteria (PGPR) on Biochemical Parameters of Coriander (Coriandrum sativum L.) Seedling

Many, microorganisms playing an important role in plant growth are used in agriculture system, especially that group of microorganisms called plant growth promoting rhizobacteria (PGPR), which can increase the growth of plant directly and indirectly; acting as biofertilizers, phytostimulators and biocontrol agent. A pot experiment was conducted to evaluate the effect of inoculation of three plant growth promoting rhizobacteira (Azatobacer, PSB, Pseudomonas) either singly or in combination on biochemical parameters of coriander seedling. There were four different seedling stages 5 DAG, 10 DAG, 15 DAG, and 20 DAG. Seeds were inoculated with single and combined solution of 108 CFU/ml of rhizobacteria. Seeds were not inoculated for the control variant. The combinations of given three PGPR had significantly increased biochemical parameters such as moisture content, total phenol, true protein, Indole-3-acetia acid (IAA), total soluble sugar, and reducing sugar in comparison to the individual and control treatment. Our study suggests that PGPR are environmental friendly and offer sustainable approach to increase production of crop and heath. So PGPR will restrict the use of chemical fertilizer in agriculture area.
