Title : Plant growth promoting rhizobacteria in agriculture
Abstract:
The use of chemical fertilizers in agriculture for the plant growth is very harmful and causes water and soil pollution. The biological approach is very eco-friendly, easy and economical. The plant growth promoting rhizobacteria are beneficial bacteria that are useful in agriculture. They have plant growth promoting traits viz., production of iron chelating compounds called siderophores; plant hormones Indole Acetic Acid (IAA), Gibberellins and Cytokinins; solubilization of phosphorus and potassium; production of enzymes, etc. The plant growth promoting rhizobacteria can be useful in agriculture to increase the crop yield. The plant growth promoting rhizobacteria include Burkholderia, Acetobacter, Herbaspirillum, Serratia, Bacillus sp., etc. The biological approach to increase the plant growth will also be sustainable. The pot experiments have shown these plant growth promoting rhizobacteria are found to improve seed germination, root and shoot length, vigour index, etc. This will be ultimately helpful to the farmers in agriculture.a
