Abstract:

Plant growth promoting bacteria (PGPB) are plant associated micro-organisms known to induce plant defences and confer beneficial effects such as increased plant growth and low susceptibility to diseases caused by pathogens. Plant growth promoting bacteria are capable of significantly altering the growth phenotype of inoculated plants. Plants inoculated with PGPBs are capable to assimilate minerals and synthesize plant hormones. A total of 46 bacteria isolates were obtained from phyllosphere of different crops (Wheat, Pearl millet, Cotton, Mungbean and Potato). All the bacterial isolates were characterized for various plant growth promoting traits i.e., NH3 excretion, IAA production, P- solublization and Nitrate reductase. Seven isolates (POK-3, WHN-2, WHN-1, PMK-3, WHK-2, COJ-4, and MUK-1) were applied as foliar spray in different treatments. The plants inoculated with the phyllospheric bacterial isolates recorded an improved plant growth in terms of plant height and potato yield. Therefore, it can be concluded that application of PGPB has immense potential to be used as agricultural crop inoculants as they promote plant growth as well as improve the health and yield of the plants.
